Comparison of blister packaging sheets

The sheet used for blister packaging is called rigid sheet or film, and commonly used are: PET rigid sheet, PVC rigid sheet, PS rigid sheet.

PS hard sheet has low density, poor toughness, easy to burn, and produces styrene gas (a harmful gas) when burning, so it is generally used to produce various industrial blister packaging trays.

Difference between PVC blister packaging and PET blister packaging

1. PET is more environmentally friendly than PVC, especially in food. For example, Coke bottles are PET blow-molded. Because PVC contains halogen, it produces toxic gas of hydrogen hydride when burned, which is not environmentally friendly.

2. PET has much better transparency and scratch resistance than PVC. In fact, the PET used to make the box is APET or PETG, both of which are modified PET, but the ingredients added are slightly different. PVC is blue, APET has some rainbow phenomenon, and APET is high in price.

3. The PVC blister packaging material is slightly softer than the PET blister packaging material.

4. When the PVC blister packaging is folded in half, there will be a white line on the folding line.

5. PET blister packaging will make a relatively clear sound when flicking with your fingers, but PVC blister packaging will not.
