The raw materials of plastic products are only plastic sheets. The thickness of film is generally less than 1.5MM. Commonly used sheets are: PVC, PET, PP, PS, and flocked sheets, gold-plated sheets and anti-static sheets on this basis. .
PVC commonly used plastic materials, soft, strong toughness, good plasticity, can be made into transparent and various colors, commonly used transparent PVC packaging electronics, cosmetics, toys and other products.
PET (A-PET) is hard, tough, high-strength, bright, environmentally friendly, non-toxic, transparent and multi-colored sheets. The disadvantage is that PET high-frequency heat sealing is more difficult, and the price is much more expensive than PVC. This material is often required to replace PVC with high-grade and environmentally friendly users.
PS density is small (light weight), environmentally friendly and non-toxic, plasticity is very good, toughness is brittle, can not be made into transparent materials, so it can only be made into the bottom type of plastic, because it is easy to crack, such plastic is not suitable for recycling
PP material is particularly soft, good toughness, environmentally friendly, non-toxic, high temperature resistant, often used as packaging for catering equipment or other high temperature resistant products; but its plasticity is poor, processing is difficult, surface gloss is poor, and the color will be lighter during processing. .
PET-G has the same physical properties as A-PET, but it can be heat sealed with high frequency, and its price is 80% more expensive than A-PET.
