PET sheet is a new type of material developed in recent years. With its excellent toughness, high strength, high transparency, and recyclable recycling, the excellent environmental performance of the combustion does not produce harmful gases. It is an environmentally friendly material and gradually bans PVC. Consumers and producers have great bargains; but prices are high. It is suitable for high-grade plastic products. The blister blister of European countries and the United States generally requires the use of PET materials, but its high thermal melting point makes it difficult to package high-frequency packages. In order to solve this problem, people have a complex on the PET surface. Layer PVC film, named PETG, but the price is higher. Mainly used for electronics, food, toys, box window, collar care, footwear packaging.
PET hard film has good toughness, high transparency, easy to burn, does not produce harmful gases when burning, and belongs to environmental protection materials, but its price is high, and it is suitable for high-grade plastic products. Generally, PET plastic film is required for plastic blister in European and American countries, but It is not easy to heat, and it brings great difficulties to the package. To solve this problem, people laminate a layer of PVC film on the surface of the PET, which is named PETG hard film, but the price is higher.
main feature:
1, has excellent transparency and finish, showing good results.
2, excellent surface decoration performance, can be printed without surface treatment, easy to suppress the pattern, easy metal processing (vacuum plating metal layer)
3, has a good mechanical strength.
4. Good barrier properties against oxygen and water vapor.
5, good chemical resistance, can withstand the erosion of a variety of chemical substances.
6, non-toxic, reliable health performance, can be used to food, medicine and medical equipment packaging, and can use Y-ray to sterilize the packaged items.
7. The adaptability to environmental protection is good, and it can be recycled economically and conveniently; when it is burned, no harmful substances harmful to the environment are produced. It is considered as an ideal packaging material that meets (ROSH) environmental protection requirements.
8, thermoforming performance is good, and ordinary PVC sheet is equivalent, you can use vacuum forming excellent performance of PET thermoforming products;
