PET sheet and its products
PET sheet is a new type of material developed in recent years. With its excellent toughness, high strength, high transparency, and recyclable recycling, it can burn and not produce harmful gas. It is an environmentally friendly material and gradually bans PVC. Great consumers and producers; but the price is high. Suitable for high-grade plastic products, blister blister in Europe and the United States generally requires PET materials, but its high thermal melting point, which brings great difficulties to high-frequency packaging, in order to solve this problem, people on the PET surface compound The layer of PVC film, named PETG, but the price is higher. Mainly used in electronics, food, toys, color box window, collar, footwear packaging.
PET hard sheet has good toughness, high transparency, easy to burn, no harmful gas when burning, and is an environmentally friendly material, but the price is high, suitable for high-grade plastic products. The blister bulbs in Europe and the United States generally require PET hard sheets, but It is not easy to heat seal, which brings great difficulty to the package. In order to solve this problem, people put a layer of PVC film on the PET surface, named PETG hard film, but the price is higher.
main feature:
1. It has excellent transparency and smoothness, and the display effect is good.
2, the surface decoration performance is excellent, can be printed without surface treatment, easy to press the pattern, easy metal processing (vacuum metallization)
3. Has good mechanical strength.
4. Good barrier performance against oxygen and water vapor.
5, good chemical resistance, can withstand the erosion of a variety of chemicals.
6, non-toxic, reliable hygienic performance, can be used for food, medicine and medical equipment packaging, and can be used to disinfect the packaged items with Y-ray.
7. It has good adaptability to environmental protection and can be recycled economically and conveniently; when it is burned, it does not produce harmful substances. It is considered to be an ideal packaging material for compliance with (ROSH) environmental protection requirements.
8. Good thermoforming performance, comparable to ordinary PVC sheet, vacuum forming can be used to produce PET thermoformed products with excellent performance;
