Difference between PVC blister packaging and pet blister packaging

时间:2022-03-31 浏览次数:

1. Material difference:

PVC blister packaging is a commonly used blister packaging material with soft quality, strong toughness and good plasticity. It can be made into transparent and various colors. It is commonly used to make blister packaging of electronic blister packaging, cosmetic blister packaging, toy gift blister packaging and other products. It is a very common blister packaging material. Pet blister packaging has the advantages of hard quality, good toughness, high strength, bright surface and can not be ignited. The environmental protection of pet blister packaging can reach food grade. Pet blister packaging has transparent and multi-color sheets.

2. The main differences in the nature of use are as follows:

Pet is more environmentally friendly than PVC, especially in food. For example, coke bottles are blow molded by PET. Because PVC contains halogen, it produces hydrogen sulfide toxic gas during combustion, which is not environmentally friendly. Secondly, pet has much better transparency and scratch resistance than PVC. In fact, pet for making boxes is APET or PETG, both of which are modified PET, but the ingredients are slightly different. PVC is blue, APET has some rainbow phenomenon, and APET is on the high side in terms of price.
