Blister sheet is a kind of plastic processing technology material. The main principle is to heat the flat plastic hard sheet to soften it, then use vacuum to absorb it on the surface of the mold, and then shape it after cooling. It is widely used in food packaging, electronic packaging, billboards, decoration and other industries.

Commonly used blister plastic sheets include: PVC, PET, PP, PS, and flocking sheets, gold-plated sheets and anti-static sheets on this basis.

PVC: The most commonly used blister material, soft, strong, and malleable. It can be made into transparent and various colors. Transparent PVC is commonly used for packaging electronics, cosmetics, toys, gifts and other products.

APET: hard, good toughness, high strength, bright surface, environmentally friendly and non-toxic, transparent and multi-color sheets. The disadvantage is that it is more difficult to heat PET with high frequency, and the price is much higher than that of PVC.

PETG: The physical properties are similar to A-PET, but it can be heat-sealed at a high frequency, and its price is more expensive than A-PET.

PS: Low density (light weight), environmentally friendly, non-toxic, very good plasticity, poor toughness and brittleness, and can not be made into transparent materials, so it can only be made into base blister, because it is easy to crack, this kind of blister is not suitable for recycling;

PP: The material is particularly soft, good toughness, environmentally friendly, non-toxic, and high temperature resistant. It is often used as packaging for dining utensils or other high temperature resistant products; but its plasticity is poor, processing is difficult, surface gloss is poor, and the color changes during processing shallow.
