The raw materials of blister products are only plastic sheets, and the film thickness is generally not more than 1.5mm. Commonly used sheets include PVC, PET, PP, PS, PE, etc.
PVC: The most commonly used blister material has soft quality, strong toughness and good plasticity, which can be made into transparent and various colors. Generally, 0.9mm (90 Silk) is his relative limit thickness!
PET(A-PET): hard, good toughness, high strength, bright surface, environmentally friendly and non-toxic, transparent and multi-color sheets. The disadvantage is that PET high frequency heat sealing is difficult, and the price is much more expensive than PVC. This material is often required to replace the general 1.5mm (150 silk) is his relative limit thickness!
PS: low density (light weight), environmental protection and non-toxic, very good plasticity, poor toughness and easy to be brittle, can not be made into transparent materials, so it can only be made into base support blister or flocking blister general 2.5mm (250 Silk) is his relative limit thickness!
PP: The material is particularly soft, with good toughness, environmental protection, non-toxic and high temperature resistance. It is often packaged as catering utensils or other high temperature resistant products; However, its plasticity is poor, processing is difficult, and its surface gloss is poor, and the color will become lighter during processing.
PET-G: the physical property is similar to that of A- PET, but it can be heated at high frequency, and its price is 80% higher than that of A- PET.
