The raw materials of blister packaging boxes are: PVC, PS, PP, PET, PETG and flocking, antistatic, conductive and other materials. A general term for a plastic product produced by a blister process for packaging, and the product is packaged with corresponding equipment. After the plastic packaging box sheet is heated at a high temperature, it is vacuum-sucked and cooled to form a plastic box shape.

The raw materials of blister products are only plastic sheets, and the thickness of the film generally does not exceed 1.5MM. The commonly used sheets are: PVC, PET, PP, PS, and flocking sheets, gold-plated sheets, and antistatic sheets based on this. .

PVC: The most commonly used blister material, which is soft, tough, and malleable, and can be made into transparent and various colors. Transparent PVC is often used to package electronics, cosmetics, toys and gifts.

PET (A-PET): hard, good toughness, high strength, bright surface, environmentally friendly, non-toxic, transparent and multi-colored sheet. 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 replaced by users who require high-end and environmentally friendly products.

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

PP: The material is particularly soft, tough, environmentally friendly, non-toxic, and resistant to high temperatures. It is often made into packaging for catering appliances or other high-temperature products; but its plasticity is poor, the processing is difficult, the surface gloss is poor, and the color changes during processing. shallow.

PET-G: Physical properties are similar to A-PET, but can be heat-sealed at high frequency. Its price is 80% more expensive than A-PET.
