The only raw materials of plastic products are plastic sheets, and the ftilm thickness generally does not exceed 1.5mm. Commonly used sheets include: PVC, PET, PP, PS, and some sheets based thereon, like flocked sheets, gold-plated sheets, and antistatic sheets.
The most commonly used plastic materials, soft, tough, good plasticity, can be made into transparent and a variety of colors, commonly used transparent PVC packaging electronics, cosmetics, toys, gifts and other products.
Hard, good toughness, high strength, bright surface, environmental protection, non-toxic, transparent and a variety of colors of the sheet. The disadvantages are PET high-frequency heat sealing is more difficult and the price is much more expensive than PVC. This material is often used to replace PVC, if some users who has demand of high-grade and environmentally friendly.
Small density (light weight), environmental protection, non-toxic, very good plasticity, poor toughness, brittleness, can not be made into bright materials, it can only be made into bottom tray type plastic. And because it's easy to crack, this type of plastic is not suitable to be recycled.
The material is particularly soft, good toughness, environmental protection, non-toxic, high temperature, often made of food utensils or other high-temperature resistant product packaging, but its poor plasticity, processing is very difficult, the surface gloss is poor, in addition, the color will get lighter when processing.
Its physical properties are similar to A-PET, but it can be high-frequency heat-sealed and its price is 80% more expensive than A-PET.
