Different Types of Paper and Their Applications

Sorry for the confusion.

Essentially there are 4 types of paper RP, RB, SP, and ST. The recycled versions of each of those types are coming up in the future.

  • RPD is the paper type.
  • RBD is the board type.
  • SPN stands for Safe Paper (food grade), ideal for food wrapping such as burger wraps
  • ST stands for Stone Paper Thermoforming Board, good for moldable applications such as disposable dishes or food containers.

For SPN you have to consider Corona treatment if you want to have them printable. If you just want to use them as a replacement layer for OPP material application, then you don't need this type of treatment.

SP products are delivered in roll format and you can find a variety of applications to be made as plastic alternative material.
