Blister packaging manufacturer The raw material of blister products is only plastic sheet, and the film thickness is generally not more than 1.5 mm. The commonly used sheet materials are PVC, PET, PP, PS, as well as flocking sheet, gold-plated sheet and anti-static sheet on this basis.

Common PVC Blister packaging The material is soft, strong in toughness and good in plasticity. It can be made into transparent and various colors. Transparent PVC is often used to package products such as electronics, cosmetics, toys and gifts.

PET (A-PET) is hard, good toughness, high strength, bright surface, environmentally friendly, non-toxic, transparent and multi color sheet. The disadvantage is that PET high cycle heat sealing is difficult, and the price is much more expensive than PVC. This material is often replaced by users who require high grade products and environmental protection.

PS has small density (light weight), environmental protection, non-toxic, very good plasticity, poor toughness and brittleness, and cannot be made into transparent materials, so it can only be made into bottom support type blister. Because it is easy to crack, this type of blister should not be recycled.

PP material is particularly soft, good toughness, environmentally friendly, non-toxic, high temperature resistant, and is often used as packaging for catering appliances or other high temperature resistant products; But its plasticity is poor, processing is difficult, surface gloss is poor, and the color will become lighter when processing.

The physical properties of PET - G are similar to those of A-PET, but it can be heat sealed with high cycle, and its price is 80% more expensive than A-PET.
