1. The PVC sheet has high toughness and is not easy to burn. It will produce chlorine gas when burning. It has a certain effect on the environment. PVC is easy to heat in. It can be sealed by a sealing machine and high wave edge. It is the main raw material for producing transparent plastic products. PVC sheet is a widely used and popular material, PVC film can be divided into two kinds of environmental protection and non environmental protection, can be made into transparent, color, anti static, gold plating, flocking and other plastic packaging products, its main features are high transparency, good surface gloss, little crystal point, small water lines, wide use, strong impact resistance, and It is easy to shape, and is widely used in products such as toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery and so on.




2. PS hard chip density is low, poor toughness, easy to burn, when burning will produce styrene gas (a harmful gas), so it is generally used to produce a variety of industrial plastic tray. PS sheet is a new type of environmental protection packaging material developed in recent years. It is widely used in medicine, food, toys and electronics with its excellent thermal forming performance, good environmental protection performance and health performance.



3. PET hard film toughness is good, is now several years of development of new materials. With its excellent toughness, high strength, high transparency, and recycling and recycling, it is easy to burn, and does not produce harmful gas in combustion. It belongs to environmental protection material and gradually outlaws PVC, but the price is high. It is suitable for high grade plastic products. The blister shell in European and American countries usually requires PET material, but its hot melting point is high, which brings great difficulties to high wave package.



4.PETG material is to solve the problem that the hot melting point of PET material is high. People compound a layer of PVC film on the PET surface, which is named PETG, but the price is higher. It is mainly used in electronics, food, toys, color box windows, collar, footwear packaging, etc.
