The raw materials of blister products only need plastic sheets, and the thickness of the film generally does not exceed 1.5MM. Commonly used sheets are: PVC, PET, PP, PS and the flocking sheet, gold-plated sheet and anti-static sheet on the base. material.


　　PVC


　　 The most commonly used blister material, soft, strong endurance, good plasticity, can be made into transparent and various colors, commonly used


　　 transparent PVC packaging products such as electronics, cosmetics, toys and gifts.


　　PET (A-PET)


　　 Hard quality, good durability, high strength, bright appearance, environmental protection, non-toxic, transparent and multi-colored 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. This material is often used by users who require advanced products and environmental protection to replace PVC.

PS


　　 low density (light weight), environmentally friendly, non-toxic, very good plasticity, poor resistance and brittleness, 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 endurance, environmentally friendly, non-toxic, and high temperature resistant. It is often made into packaging for dining utensils or other high temperature resistant products; but its plasticity is poor, processing is difficult, the surface gloss is poor, and the color becomes lighter during processing.


　　PET-G


　　 The physical properties are similar to A-PET, but it can be heat-sealed at a high frequency, and its price is 80% more expensive than A-PET.
