1. PVC sheet has high toughness and is not easy to burn. It will produce chlorine gas when burning, which will cause certain impact on the environment. PVC is easy to heat seal. Sealing machine and high frequency edge banding can be used. It is the main raw material for producing transparent plastic products.

2. PS hard film has low density, poor toughness, easy to burn, and styrene gas (belonging to harmful gas) will be generated during burning, so it is generally used to produce plastic trays for various industries.

3. PET hard sheet has good toughness and is a new material developed in recent years. With its excellent toughness, high strength, high transparency, and recyclability, it is easy to burn and does not produce harmful gases during combustion. It is an environmentally friendly material and gradually bans PVC, but the price is high.

Four PETG material is to solve the problem of high thermal melting point of PET material. People compound a layer of PVC film on the surface of PET, named PETG, but the price is higher. Mainly used in electronics, food, toys, color box windows, collar holders, shoe packaging, etc.
