Stone heat sealable paper bags are ideal for food packaging, items such as spices, cheese slices, and thick pastes such as ketchup and mayonnaise. These bags provide moisture, oxygen and UV protection, have been tested to quality standards, and are made entirely of heat-sealable materials.
Custom stone heat sealable paper bags for food
Packaging in the food packaging industry requires custom printing of its sealed bags, as it is often necessary to provide consumers with specific instructions on how to enjoy food properly. In many countries/regions, especially on edible foods, the product description, ingredient weight, manufacturing, and expiration date are printed on each pouch, which is also required by law. Companies can print their sealed bags in the most attractive way by customizing all legal information required by law and the company’s name and logo.
Types of stone heat sealable paper bags
Standard flat heat-sealed bags: These are one of the most common types of bags used for food packaging. One or both sides of these bags are transparent, so you can put the contents in front of everyone to display.
Laminated heavy products: Made of stronger materials than standard materials, they are crimped and sealed on the bottom, with a central weld on the back.
Metalized flat bags: These are good choices for coffee powder, powdered spices, food supplements and other products. These bags protect against ultraviolet rays, moisture, and oxygen, and have ripping options at both ends of the bag.
For your company, the most feasible packaging bag depends on the type of product you plan to produce and package. Before finalizing the choice, three things need to be determined:
Bag type: How strong do you need to be? Do you only need packaging options or do you have to consider moisture resistance? You can choose transparent, laminated, transparent front solid back, metallized or composite stable bag.
Printing type: It depends to a large extent on your budget. You can perform monochrome, multicolor, full CMYK, matt, metal or holographic printing.
Seal type and shape: can include a tear at one of the two ends of the bag, a child-resistant sealed bag, a DOY bag, germination and hanging holes or handles.
Waterproof stone paper is particularly prominent in environmental protection. Compared with the traditional papermaking process, the production process does not produce waste water, waste gas, waste residue, and is a pollution-free green environmental protection project. In terms of water use, traditional papermaking consumes 100 tons of fresh water per ton of production, while the stone paper production process requires no water for the entire production.
In terms of raw materials, the main raw material of traditional papermaking is forest resources, while the main raw material of stone paper production process is coal gangue, slag and other stones, which do not consume forest resources. Traditional fiber paper can be recycled into recycled paper after use up to realize resource reuse. Thermoformed stone paper can also be recycled and reused. After recycling, it can produce dark-colored packaging paper, can also be made into various signs, flower pots, etc., and the used stone paper is recycled or treated as garbage.
When incinerated, only non-toxic resin can be burned. Stone powder can promote the contact between resin and air, accelerate the complete combustion, and avoid black smoke caused by suffocation due to lack of oxygen. There is no toxic exhaust gas after combustion. Helps mitigate and improve global warming caused by carbon dioxide.
Even if discarded outdoors, the stone paper will automatically embrittle into a broken eggshell shape after being exposed to sunlight for about 6 months, reducing the earth and returning to nature; it can be degraded into a powder (inorganic mineral powder) after being buried in the ground for 1 year. Will cause environmental pollution. It can replace a part of traditional wood papermaking.
In general paper, it may use a lot of water in the process of making it, but thermoforming stone paper hardly uses water, and the process does not bleach. So the biggest difference between us and ordinary paper is that the original color of stone powder will affect the color of paper. For example, coal gangue paper will be slightly black, depending on the purpose of the paper.
This project is dedicated to the development and research of functional thermoformed stone paper packaging materials. Applying the idea of integrated innovation, using stone paper as the raw material, combining the excellent properties of stone paper with the mechanical properties of honeycomb paperboard and corrugated paperboard, the development of stone paper composite corrugated paperboard and stone paper honeycomb paperboard with various functions and its Related production processes, and creatively introducing foaming technology into the production of stone paper, reducing the proportion and cost of stone paper materials.
Through the research and development of stone paper production technology and the exploration of performance characteristics, the application of stone paper materials in the packaging field is promoted. The core layer of the stone paper honeycomb paperboard is formed by a chain compression molding process, that is, the core layer is pressed by the core paperboard through a chain molding device with a protruding honeycomb hexagonal prism structure, and then the prepared core layer and the stone paper are pressed. Tissue paper is melt-bonded at an instant high temperature.
Compared with the traditional corrugated cardboard of the same specification, the stone paper composite corrugated cardboard with a thickness of 4.50mm has a break resistance of at least 2.5 times and a puncture strength of 1.7 times. The core layer of the stone paper corrugated cardboard adopts the extrusion flow calendering molding process, that is, the stone paper is directly extruded and cooled in a molten state through a corrugated die to obtain a core layer. Each bonding surface is pre-heated and bonded by instantaneous high-temperature hot-melt bonding. Compared with the conventional honeycomb paperboard of the same specification, the prepared honeycomb paperboard with a basis weight of 202g / m2 has a flattening strength of 2.6 times that of the traditional honeycomb paperboard, and the burst resistance is at least 2.5 times that.
Lightweight stone paper, which is a light weight multi-layer stone paper composed of foamed stone paper and non-foamed stone paper. Foaming and hot-melt compounding are the key technologies. Multi-channel extrusion is used. Machine, followed by hot press foaming. During the production process of lightweight stone paper, AC foaming agent with a weight percentage of 0.1 ~ 0.7% is selected for the foaming process, and the temperature of the multi-layer runner of the extruder is 160 ~ 170 degrees Celsius, and the hot-pressing foaming temperature is 180- 200 degrees Celsius

3.Environmental protection stone paper products.
It is mainly used to replace some traditional cultural paper, packaging paper and special paper. This type of product changes the traditional papermaking process technology, does not use wood pulp, does not need to cut trees, does not emit strong acids and alkalis and other chemical substances, and does not discharge wastewater
Believe many people may not have discovered that stone paper has begun to enter our lives. It is possible that the handbags, lunch boxes, and packaging bags we use are made of stone paper, so how did the stone become soft? What about paper?
Stone heat seal paper is paper made from stone, which is called synthetic paper in the industry. The main material of the stone is calcium carbonate, which is processed by a special process using calcium carbonate as a raw material, polymer materials and various inorganic substances as auxiliary materials. The whole process requires no pulping, no water addition, no strong alkali, strong acid, bleaching agent, no waste water, waste gas, waste residue, especially energy saving and environmental protection. This is the embodiment of new paper technology with modern technical characteristics.
To make stone paper, the first step is to pulverize and grind the stone that is going to be used for papermaking with professional mill equipment, and mix 80% stone powder with 15% polyethylene and 5% additives. Using the principle of polymer interface chemistry and the characteristics of filling modification, the mixed materials are processed by mixing, extrusion, coating and other processes.
Stone powder, polyethylene and additives are made together with a principle similar to what we usually do at home and dough. Stone powder is equivalent to flour, polyethylene acts as water, and additives are equivalent to yeast. By using a granulator, the three mixed materials are pressed into dough and produced according to different needs. If a thin paper is needed, the material is blown into a thin paper. If the demand is thick paper, a die is used. Pressed into thick paper.
Stone heat seal paper cannot completely replace the traditional wood pulp and straw paper, but it can be partially replaced, about 60%. Stone papermaking can not only solve the environmental pollution caused by traditional papermaking, but also white pollution caused by a large number of plastic packaging materials. Therefore, this papermaking technology has great economic value and social significance.
Features: simple production process; large investment, high output, low energy consumption; no plant fiber, no tree felling, can save a lot of wood, protect natural ecology; no need to add chemical materials such as strong acid, strong alkali, bleaching agent; no discharge of waste water, waste residue and toxic and harmful gases are green products.
The stone heat seal paper has good mechanical properties, waterproof, moisture-proof, moth-proof, fold-resistant, tear-resistant, oil-resistant, non-toxic, odorless, non-polluting, stable geometric size, high printing clarity, good effect, and can be naturally degraded into powder after disposal Features such as nature.

Thermoformed large wrapping paper, also known as thermoformed calcium carbonate cardboard, is mainly composed of calcium carbonate.
In the production process of stone board, calcium carbonate is mainly used as the main raw material. The entire production process does not need to add a drop of water or consume wood, which saves precious water resources and forest resources.
Using stone to make products, the current technical problem to be solved is how to provide a low-cost, high-performance stone cardboard. In order to solve this technical problem, the technical solution adopted is to produce a three-layer composite structure of stone cardboard, including an upper surface layer, a lower layer and an intermediate layer. The so-called upper surface layer, lower surface layer and middle layer are all large wrapping paper layers.
The thickness of the above-mentioned stone cardboard is 0.3 to 2.5 mm, and the thickness ratio of the surface layer to the intermediate layer is 1: 2.5 to 1: 4.5. The upper and lower layers are stone paper layers with low stone powder content, and the middle layer is stone paper layers with high stone powder content.
Folders / file boxes currently on the market, including their skins, are also made of stone cardboard. This new type of stone cardboard has a three-layer composite structure, with an upper surface layer, a lower surface layer and an intermediate layer of the stone cardboard. Each layer can use stone paper layers with different stone powder content, and the middle layer can use stone paper layers with high stone powder content to reduce the cost of cardboard; the upper and lower layers can use stone paper layers with medium or low stone powder content. In order to improve the strength, toughness and surface finish of the product, the three-layer composite structure of stone cardboard can realize the unification of high performance and low cost of the product.

The so-called stone papermaking is to grind calcium carbonate, the main component of the stone, into ultra-fine particles, and then blow the paper with polyethylene and glue. In the context of global calls for energy conservation and emission reduction, this non-new stone paper has been labeled with the "fashion" label of low-carbon emission reduction and environmental protection, and has entered the public's vision.
However, as a paper-making product, stone paper has its unique functionality, but its technology needs to be improved, and there are still problems in recycling. Therefore, we should look at stone paper dialectically.
Stone paper is just a product of the paper industry and has been around for more than 40 years. It is nothing new. Stone paper uses calcium carbonate, the main ingredient of stone, as the main raw material, so people call it stone paper.
Stone paper is a synthetic paper in the paper industry and a plastic film in the plastics industry. As early as the 1970s, the Chinese paper industry had been conducting research and development on synthetic paper. Because synthetic paper has a plastic component, it is not easy to tear, so synthetic paper is commonly known as "tear-proof."
In the 1960s, synthetic paper, the predecessor of stone paper, appeared in Japan. Over the years, the annual output of synthetic paper in western countries has increased at a rate of 10%. In the early stage of China, stone paper was mainly imported from abroad. In the later period, a few companies also started to develop synthetic paper. Stone energy is one of them.
Problems still need to be resolved
In the production process, no wood is consumed, no "three wastes" are emitted, no drop of water is used, and the cost is low because the raw material is limestone. Stone paper was described by the media as a low-carbon environmental protection star product. Despite this, experts still questioned stone paper.
1. Adaptability problem
Stone paper currently on the market is thicker and heavier than ordinary paper. Stone paper of A4 size weighs 1.3 grams, while plain paper of the same specification weighs 0.7 grams. In addition, stone paper has better ink absorption than plastic, but much worse than vegetable fiber paper.
2. Raw material problems
Stone paper uses plastic components such as polyethylene. Plastic is derived from petroleum, but China's petroleum is currently relatively scarce. Some companies claim that the output of stone paper will reach more than 5 million tons in the future, which will inevitably consume a lot of oil, so there may be a shortage of raw materials. "
3. Recycling issues
"Stone paper will embrittle and crack for a long time, but the plastic macromolecules in it cannot be degraded without using special equipment." If the stone paper and fiber paper are recycled together, the stone paper will become fused and sticky once it is melted On the inside wall of the equipment, it can cause harm to the equipment.
The appearance of stone paper(stone notepad paper) is gradually being valued at home and abroad. Unlike traditional papermaking, the raw material of stone paper is mainly stone, a small amount of resin and some additives, which are made by a series of physical methods.
Characteristics of stone paper:
• Simple production process; large investment, high output and low energy consumption.
• By not using plant fiber or cutting trees, a large amount of wood can be saved and natural ecology can be protected.
• It does not need to add chemical materials such as strong acid, strong alkali, bleach, and does not discharge waste water, waste residue and toxic and harmful gases.
• The product has the characteristics of good mechanical properties, waterproof, moisture-proof, moth-proof, folding-resistant, tear-resistant, odorless, pollution-free, stable geometric dimensions, high printing clarity, and can be naturally degraded into powder and returned to nature after being discarded.
Classification of stone paper(stone notepad paper):
The first category: a series of degradable environmentally friendly packaging materials.
This product is mainly used to replace traditional plastic packaging products. There are two major series of industrial packaging materials and living packaging materials. Among them, industrial packaging materials include: dust covers and protective covers for electronics, home appliances and industrial equipment. Living packaging materials include various packaging bags, shopping bags, garbage bags and roll bags used in daily life.
The second category: environmentally friendly thermoformed stone cardboard products.
Due to advantages in raw materials, production technology, and technological processes, thermoformed stone cardboard products are the only boards in the world that are close to zero benzene and zero formaldehyde. The products have no harmful substances such as heavy metals, no odor, moisture resistance, and flame retardant. And antibacterial functions. The environmental indicators of its products have not only passed the testing and certification of relevant national testing agencies, but also reached the European Union's testing standards, and have made major breakthroughs in health and environmental protection!
The third category: environmental protection stone paper sheet products.
It is mainly used to replace some traditional use plates, packaging plates and special plates. This type of product changes the traditional board making technology, does not use wood pulp, does not need to cut down trees, does not emit strong acids, strong alkalis and other chemical substances, and does not discharge wastewater.
The appearance of stone paper is gradually being valued at home and abroad. Unlike traditional papermaking, the raw material of stone paper is mainly stone, a small amount of resin and some additives, which are made by a series of physical methods. Compared with the traditional paper manufacturing process, it is more energy efficient and environmentally friendly.
So, can stone paper replace traditional paper?
The whole process of stone paper does not require water beating and papermaking, and does not need to add a large amount of chemical agents, so it does not cause the problem of difficult wastewater discharge treatment, which is more environmentally friendly than traditional papermaking. The paper made from stone has a certain degree of whiteness, which is characterized by high tensile strength, good resistance to folding and tearing, tear resistance, water resistance, oil resistance, chemical resistance, and low temperature and humidity resistance.
In addition, the surface of the stone paper is smooth, it is not easy to grow mold, and it is not afraid of insects. Stone paper is suitable for printing, because its ink absorption is very good, and the ink printing has high definition and accuracy. At the same time, stone paper is naturally degradable, which is more environmentally friendly than traditional paper.
Of course, stone paper has its shortcomings. Under normal circumstances, the life of stone paper is about 20-30 years. However, stone paper will be powdered in less than 6 months under direct sunlight. Therefore, the storage time of stone paper is shorter than that of traditional paper. Due to such characteristics, stone paper cannot be used for storage of important documents.
In addition to storage time, stone paper is heavier than traditional paper, which is not convenient for binding and transportation. The scope of application is not as extensive as traditional paper. At present, stone paper is mainly used for printing books, newspapers, notebooks, product manuals, advertising lists, desk calendars, playing cards, and can also be made into various decorative packaging bags, shopping bags, and packaging boxes.
The main raw materials of stone paper are limestone and petroleum. The polyethylene, cement, etc. used in stone paper come from petroleum. Petroleum is a limited and non-renewable resource worldwide. Therefore, the sustainability of the development of the stone paper industry is facing severe challenges.
Traditional paper mainly uses forestry, plants and other raw materials with strong regeneration ability. As long as the country's reasonable planning forms a virtuous cycle of planting, conservation, felling, and replanting, it can meet the requirements of sustainable regeneration.
Stone paper has huge differences from traditional papermaking in terms of raw materials and production technology, which is a technological breakthrough; however, due to the narrow application range and non-renewable raw materials, it can only be used as a supplement to ordinary paper and cannot be completely replaced.
The rise of stone paper, a new material between paper and plastic, has caused controversy as a new thing.
While receiving praise, some experts also believe that although the production process of stone paper is low-carbon and energy-saving, whether it is an emerging thing or not is really worthy of discussion.
First, the raw materials of thermoformed stone paper are mainly calcium carbonate and high-molecular polymers based on petroleum. It is obviously a waste of resources for China's current consumption of nearly 90 million tons of paper products.
In addition, scientific experiments have proven that it takes at least two or three hundred years for general plastics to degrade into environmentally friendly, less harmful fragments.
Therefore, stone paper cannot be truly completely recycled and degraded. However, for renewable plant resources such as wood, reed and more than 60% of plant fiber paper made from waste paper, it is easy to recycle and degrade.
Secondly, in terms of product performance, thermoformed stone paper needs to be added with polyethylene to make a composite paper, similar to an ultra-thin "plastic paper". In comparison, traditional plant fiber paper has many excellent features such as good absorbency, air permeability, and printability. It can be converted into pulp after blistering, and easily degraded under natural conditions. These characteristics are exactly what airtight stone paper does not have.
In terms of technology, China has accumulated rich experience in papermaking for thousands of years. Modern technology has made the production process less and less polluting the environment, and large-scale enterprises have reached environmental protection standards.
The use of calcium carbonate as a filler in the paper industry has a long history. At present, paper products have been used up to nearly 20%. Therefore, the use of calcium carbonate as an ingredient in paper is no longer an innovation.

Stone paper sheet is made of marble, limestone, coal gangue, and even slag, using polymer materials and a variety of inorganic materials as auxiliary materials, using the principle of polymer interface chemistry and the characteristics of filling and modification. , Blow molding processing to produce a new type of paper that can be recycled and has modern technical characteristics.
Protect resources and save energy
The stone notepad paper board comes from the mine and does not need to cut vegetation, which is a great protection for the forest. The stone paper production process mainly uses calcium carbonate as the main raw material. The entire production process does not need to add a drop of water, which saves valuable water resources.
At the same time, the energy consumption is lower than that of traditional wood pulp and paper, which helps to improve global warming caused by carbon dioxide.
Reduce pollution emissions
The production of stone notepad paper plates does not require water washing at all, nor does it require strong acids, alkalis and bleaching agents, so there is no problem of wastewater discharge and no pollution of water resources.
Recycling and degradation
Stone heat seal paper plates can be recycled through plastic products after use. After being collected, they can be crushed and extruded to produce colored plastic bags, flower pots, and plastic buckets.
If it is treated as garbage and sent to the incinerator for combustion, no toxic gas will be generated. Because the stone paper sheet contains a large amount of stone powder and a small amount of non-toxic resin, when the resin is burned, the stone powder will be pulverized, which promotes the resin to contact with the air and accelerates the complete combustion of the resin, so black smoke will not be generated due to lack of oxygen and smoldering during combustion . After the non-toxic resin burns, there is no toxic exhaust gas, and the amount of carbon dioxide emission is small.
The thermoformed stone paper hotel products have passed the US Food and Drug Administration (FDA) test, including three types of RP \ RB \ ST stone paper series, which indicates that the stone paper products are non-toxic and harmless and can be directly contacted with food.
Legend has it that fine stones can sing, can stones make paper? The answer is yes, the waste of coal gangue can make paper is no longer a fantasy. The box made of coal gangue has a plastic feeling when touched by hand, but its toughness is very strong, and it will not tear when pulled hard. Take it in your hand, it is softer than ordinary fiber paper products. Their raw materials are not traditional pulp, but stone.
The limestone, which is made of coal gangue and tailings slag, is crushed, screened and ground to form ultrafine modified ore powder. After calcination into quicklime with a calcium content of 57% or more, it is ground into nanometer ultrafine whitening powder and added. 20% of specific PE, PP and other additives are processed by special processes such as casting and stretching, three-layer co-extrusion, blow molding, and stone paper goods.
The paper's scientific name is 'environmental synthetic paper', and its raw material is limestone. The stone content of each paper is about 70% to 80%. The characteristics of the stone wrapping paper material give it special properties. The stone carton made of this paper has a particularly high compressive strength, folding resistance, waterproofness and integral molding. According to statistical analysis of the data, the synthetic calcium polymer board has a burst strength of up to 264 KPa and a double side pressure strength compared with ordinary corrugated board. Even in the environment of minus 40 degrees Celsius to minus 80 degrees Celsius, the stone carton will not be deformed and damaged, especially suitable for the transshipment packaging of fruits, vegetables, frozen seafood and so on.
The biggest feature of large wrapping paper is environmental protection. Since the entire production process is a physical change, complete zero emissions are achieved. In terms of water use, traditional papermaking consumes 100 tons of fresh water per ton of paper produced, while the entire production process of the stone paper goods process does not require water. In the raw materials, the main raw material of traditional papermaking is forest and grass resources, and the main raw materials of the stone paper production process are coal gangue, slag and other stone materials. The amount of stone wrapping paper produced by one ton of stone is equivalent to 20 trees. The most important thing is that the product can be recycled indefinitely. After the used carton is recycled, it can be directly crushed and processed without causing secondary pollution. Stone paper is not only non-flammable, but the only product produced after combustion is white calcium carbonate powder, which can be used as a raw material.
A seemingly simple stone board production line is supported by a number of production technology invention patents and new equipment patents. The solid waste such as coal gangue and tailings slag is consumed cleanly, and all are made into recyclable “green”stone paper goods.

The difference between stone paper and ordinary paper
The appearance of stone paper will save a lot of trees. Producing a ton of stone paper help reduce the cutting of 20 trees. In the manufacturing process, there is no need of water, agents such as bleach, strong acid, strong alkali. It does not discharge waste water, waste gas and does not produce waste. Notebooks made of stone paper cost a little more than ordinary ones, ranging from 8 to 10 yuan each.
From the perspective of environmental protection, China's waste recycling system is in a leading position in the world. For example, when you buy a car, you need to add 5000 yuan to the commission. After the car is scrapped and sent to the recycling center, you can take back 5,000 yuan. The plastic fiber clothes produced in China are made from waste mineral water bottles. This product has the vast majority of the global market share. In the field of agricultural science and technology, we hope that through the rapid development of enterprises, we can share our environmental and creative ideas and scientific and technological achievements with the world.

Stone paper disposal goods is mainly composed of stone powder (calcium carbonate), resin, etc. At present, many domestic enterprises or research institutions claim to have mastered this technology. From the information that has been published, the technologies of each enterprise are similar. The proportions are close. It's basically 80% stone powder with 20% additives. The specific addition composition, proportion and operation process are different.
It is reported, there are 3 kinds of the process of green paper such as stone paper mainly.
The first is calendering by batching, mixing, modification, extrusion materials, calendering. The shortcomings of calendering process is that it is complex, and it is generally used to produce more than 0.1mm of environmentally friendly paper products. The product proportion is big, and the equipment price is expensive, but the product surface is smooth. It is suitable for printing products like the advanced sample and the book cover.
The second is the flow method. Instead of calender, we can produce green paper of different thickness. However, the distribution of molecular chain in environmental paper is unidirectional, so the vertical, horizontal and physical properties of environmental paper products are quite different. This is a major shortcoming of environmentally friendly paper.
The third is the bidirectional stretch method. In the bidirectional stretching process, there will be some small gaps between the substrate plastic and the filling material, thus reducing the proportion and cost of environmental protection paper. Due to the refraction of light by these small gaps, the environmental protection paper produced by it has a good appearance and has been widely used in fields such as packaging, printing, advertising.

From the perspective of replacing the traditional part of plastic packaging, it can save a lot of strategic resources, oil, for the country. But some experts question whether it can be degraded. As a new thing, the stone paper moves on in the controversy.
What is stone paper?
Stone paper is also called stone material paper. Limestone mineral resources with large reserves and wide distribution (calcium carbonate content up to 70~80% is the main source and the high polymer is the auxiliary material (the content is 20-30%). It makes use of the chemical principle of Polymer interface and the feature of polymer modification. After special processing, it adpots polymer extrusion, blowing molding process. It is a kind of processed paper. Stone paper has the same writing performance and printing effect as plant fiber paper, and has the core performance of plastic packaging.
How does it contribute to environmental protection?
Resource conservation and energy conservation. Stone paper comes from mines. The trees do not need to be cut down. It is a great protection for the forest. Calcium carbonate is the main raw material, so no water need to adding in the process. It saves precious water resources. At the same time, the energy consumption is lower than the traditional wood pulp paper. It will help solve problems such as global warming caused by carbon dioxide.

It is said that stone paper is widely used in garbage bags, shopping bags, food bags, etc. It can also be used in cultural paper, such as printing paper, writing paper, etc. It can also be used in fields such as building materials decoration, industrial packaging. It can even be used for special paper, such as field work paper, military special paper, etc. It is widely used.
The economic benefits and social significance of stone paper are enormous
Traditional papermaking technology needs to cut down a lot of wood and use a lot of water. It discharges sewage and toxic and harmful substances in the production process, causing serious harm to the environment and human health. Throughout the production process, stone paper does not need water, strong acid, strong alkali, bleach powder and many organic chlorides. Compared with the traditional papermaking process, it saves several important pollution links such as cooking, washing and bleaching, and fundamentally eliminates the pollution problem caused by "three wastes" in papermaking process.
