Is there a difference in the thickness of the blister sheet?
Jan 19,2021

The usage of pet blister sheets  in life can be said to be very wide. It is very necessary to choose and use blister sheet reasonably. The use of blister sheet is a good choice for industry processing and production. In fact, the thickness of the blister sheet itself is required when it is used.


1. The thickness of ordinary thin blister is 0.08~2.0mm, mainly using PVC sheet, PP sheet, PS (HIPS) sheet, PET (including APET and PETG) sheet, PE sheet, BOPS sheet and recyclable Paper trays and other non-thermoformed blister products of various materials and effects such as folding, half folding, three folding, cylinder, folding box, heaven and earth box, high frequency, etc., are widely used in food, medicine, electronics, toys, computers, daily necessities, Cosmetics and mechanical hardware industries.                      

2. The thickness of special thick blister is 2~8.0mm, mainly using PVC sheet, PP sheet, PS (HIPS) sheet, PET (including APET and PETG) sheet, ABS sheet, PC sheet, PE Sheets and PMMA sheets and other injection-molded blister products of various materials and effects. The main products are refrigerator liners, advertising light boxes, commodity display stands, pet cage chassis, rear projection TV back shells and various mechanical panels, etc. Instead of injection molding products, it has the advantages of low mold cost (only 1/20 of injection mold), short production cycle, and short mold development time (usually only 3 to 5 days).

    There are some differences between the materials used in ordinary thin blister and special thick blister, but PVC sheet, PET sheet, PP sheet and PS sheet all occupy a place in these two types of blister products, which can be called blister products. The "four kings" of the sheet family!

    PVC sheet has moderate toughness and is not easy to burn. It will produce chlorine when burned, which will affect the environment. PVC is easy to heat and can be sealed with a sealing machine and high-frequency machine. It is the main raw material for producing transparent plastic products.

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

    plastic PET sheet has good toughness, high transparency, easy to burn, and does not produce harmful gas when burned. It is an environmentally friendly material, but the price is high, and it is suitable for high-end blister products. The blister blister in European and American countries generally requires PET hard film, but It is not easy to heat seal, which brings great difficulties to packaging. In order to solve this problem, people compound a layer of PVC film on the surface of PET, which is named PETG rigid sheet.
