First, PVC sheet has high toughness, is not easy to burn, will generate chlorine gas when burning, and has certain impact on the environment. PVC is easy to heat, can be sealed by sealing machine and high frequency sealing, and 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 environmental protection and non-environmental protection. It can be made into transparent, colored, gold-plated, flocked and Other blister packaging products. High, good surface gloss, less crystal point, small water grain, wide application, strong impact resistance, and easy to shape. The products are widely used in toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery and other products. .
Second, PS hard film has low density, poor toughness, easy to burn, and produces styrene gas (hazardous gas) when burned, so it is generally used to produce various industrial plastic trays. PS sheet is a new type of environmentally-friendly packaging material developed in recent years. It is widely used in medicine, food and electronics due to its excellent thermoforming properties, good environmental performance and hygienic performance.
Third, the PET hard sheet has good toughness and is a new type of material developed in recent years. With its excellent toughness, high transparency, and recyclable recycling, it is easy to burn, does not produce harmful gases when burned, and is an environmentally friendly material that gradually bans PVC, but at a high price. Suitable for high-grade plastic products, blister blister in Europe and the United States generally requires PET materials, but its high thermal melting point, which brings great difficulties to high-frequency packaging, in order to solve this problem, people on the PET surface compound The layer of PVC film, named PETG, but the price is higher. Mainly used in electronics, food, toys, color box windows, footwear packaging, etc.
