Now developed countries require plastic packaging products in line with the EU ROHS environmental protection requirements, use or contain cadmium (Cd), lead (Pb), mercury (Hg), hexavalent chromium (Cr6 +), the four heavy metals and polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE) flame retardants in electrical and electronic products will not be allowed to enter the EU market, blister packaging is no exception as electronic products packaging accessories, plastic products raw materials, the only plastic sheet, film thicknessgenerally not more than 1.5MM, Top sheet: PVC, PET, PP, PS, and on this basis the flocking sheet, gold-plated sheet, and anti-static sheet.
    PVC: The most commonly used plastic material, soft, toughness, good plasticity, can be made transparent and a variety of colors, used transparent PVC packaging electronics, cosmetics, toys, gifts and other products.
    PET (A-PET): hard, good toughness, high strength, surface brightness, environmental non-toxic, transparent sheet and a variety of colors. Frequency heat sealing of PET is difficult, the price is much more expensive than PVC, this material often requires high-end products and environmentally friendly user the replace PVCPS: density (light weight), environmental non-toxic plastic is very good, poor toughness brittle, not made of brightly lit material, and therefore can only be made ​​bottom bracket class Blister, its easy to crack, such plastic recycling should not be
    PP: special soft material, good toughness, environmental non-toxic, high temperature, often made ​​dining utensils, or other high-temperature products packaging; its plasticity and difficult process, surface gloss, and processing color will become.
