PET-If the pallet needs to be transparent
High transparency + food grade safety
Medium heat resistance + impact resistance (such as electronic product lining)
Need recyclable environmental certification (such as export to the EU market)
PET materials dominate the application of transparent vacuum forming trays, mainly due to the following advantages: clarity close to glass, can perfectly display the goods inside, high surface gloss, improve the product display grade, temperature resistance -20℃~70℃: suitable for room temperature packaging (some high temperature resistant PET can withstand 100℃ for a short time), belongs to Class 1 recyclable plastic (♳ logo), meets the EU SUP plastic ban replacement requirements.
PVC-Need low cost and not food and medical use
Antistatic PVC: used for electronic component packaging
Flame retardant PVC: used for special products such as batteries
Weather-resistant PVC: add stabilizers to extend outdoor service life
Application scenarios:
Precision electronic component trays
Hazardous goods packaging
Outdoor storage packaging
PP- Need environmental protection, food safety grade
PP frv0 battery cover meets UL94 flame retardant standards
PP food grade packing tray
Typical application areas of HDPE blister
Dominant applications of industrial packaging, heavy parts trays, automobile engine parts transport trays, industrial valve blister lining (outstanding oil resistance)
Industry innovation application cases, automotive battery trays: passed UL94 V-0 flame retardant certification, 40% weight reduction to replace metal trays.
ABS single-sided TPU and ABS double-sided TPU
Trays are suitable for packaging aluminum parts, aluminum auto parts, need protection, turnover in turnover boxes, very strong strength, and relatively high cost.
This article compares the transparency, temperature resistance, environmental protection and price of PET, PVC, HDPE, and PS blister materials in detail to help you choose the most suitable blister packaging solution that meets FDA and EU environmental standards
