PP synthetic paper is made by mixing and compressing main raw materials such as polypropylene resin, polyethylene resin and natural stone powder. PEPA pearl paper is pressed by polyolefin resin which is cracked by petroleum and then polymerized. The characteristics of both products are made of plastic material imitation paper, without using the slightest forest resources, to replace the new products of natural paper with functionality. Synthetic paper and pearl paper not only have the waterproof, durable, and tear-free plastic properties that natural paper can't reach, but also have excellent printing processing adaptability of natural paper. It can be widely used in letterpress, lithographic, gravure, screen, etc. Post-processing areas such as printing and bronzing, embossing, cutting, drilling, origami
　　 PP paper has a kind of photo-adhesive, which is “back-adhesive PP synthetic paper”. It can be used for printing, etc., and it can be used for printing.
　　 PVC is actually a vinyl polymer material whose material is a non-crystalline material. PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives in actual use. It has non-flammability, high strength, weather resistance and excellent geometric stability. PVC is highly resistant to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid, concentrated nitric acid, and is also not suitable for contact with aromatic hydrocarbons or chlorinated hydrocarbons. In addition, the term "person vs computer" in the game, abbreviated as PVC, and PVC human form are often referred to as PVC, etc.
