PVC sheet is a widely used and popular material. PVC Film can be divided into food grade and industrial grade, and it can be made into transparent, colorful, anti-static, gold-plated, flocking, etc. For vacuum forming, its main characteristics are high transparency, good surface gloss, less crystal points, small water lines, wide use, strong impact resistance, and easy molding. The finished product meets the US FDA and Japanese PL food hygiene standards. It is widely used in the outer packaging of toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery and other products.

1. If classified according to the thickness of the material, it can be divided into
A. The thickness of ordinary thin blister is 0.14~5.0mm-mainly made of various materials and effects such as PVC, PP, PS (HIPS), PET (including APET and PETG), PE, BOPS and recyclable paper trays Folding, half-folding, three-folding, cylinder, Folding Box, heaven and earth box, high frequency and other non-thermoformed blister products are widely used in food, medicine, electronics, toys, computers, daily necessities, cosmetics, machinery hardware and other industries.
B. The thickness of the special thick blister is 0.14~5.0mm-mainly the plastic injection products with various materials and effects such as PVC, PP, PS (HIPS), PET), ABS, PC, PE, etc.
The reason for not classifying the types of materials is mainly considering that there are some differences between the materials used in ordinary thin blister and special thick blister, but PVC, PP, PS and PET are all in these two types of blister products. To have a role to play!
PVC hard film has moderate toughness and is not easy to burn. It will produce chlorine when burned, which will affect the environment. PVC is easy to heat and can be sealed with a sealing machine and high-frequency machine. It is the main raw material for producing transparent plastic products.
PS hard film has low density, poor toughness, easy to burn, and will produce styrene gas (a harmful gas) when burned, so it is generally used to produce various industrial blister trays.
PET hard film has good toughness, high transparency, easy to burn, and does not produce harmful gas when burned. It is an environmentally friendly material, but the price is high, and it is suitable for high-end blister products. The blister blister in European and American countries generally requires PET hard film, but It is not easy to heat seal, which brings great difficulties to packaging. In order to solve this problem, people compound a layer of PVC film on the surface of PET, named PETG rigid sheet, but the price is higher.
