Release time: 2016年01月18日

A high toughness PVC sheets, not combustion, combustion will produce chlorine, some impact on the environment, PVC heat easily, can sealing machine and high frequency edge, it is the main raw material for the production of transparent plastic products. PVC sheet is a versatile and popular material, PVC film can be divided into two kinds of green environmental protection and are not, can be made transparent, colored, anti-static, gold-plated, flocking, and other kinds of plastic packaging products, which The main features of high transparency, surface gloss, less grain, small waterlines, versatile, high impact resistance, and easy to shape, products widely used in toys, food, electronics, pharmaceuticals, electrical appliances, gifts, cosmetics, stationery, etc. product packaging.

Two, PS hard piece of low density, poor toughness, easy combustion, will produce styrene gas (which is harmful gases) when burned, it is generally used in the production of a variety of industrial plastic tray. PS sheet in recent years developed a new type of environmentally friendly packaging material, with its excellent thermoforming performance, good environmental performance and health performance, widely used in medicine, food, toys, electronics.

Three, PET rigid sheet toughness, in recent years developed a new type of material. With its excellent toughness, high strength, high transparency, as well as the use of recyclable, easy to burn, does not produce harmful gases when burned, are environmentally friendly materials and gradually ban PVC, but the price is high. Suitable for high-end plastic products, blister European countries generally require the use of PET material, but its high melt point, has caused great difficulties to the high-frequency package, in order to solve this problem, people on the surface of the composite a PET layer PVC film, named PETG, but the price is higher. Mainly used in electronics, food, toys, box window, collar care, footwear and packaging. Its advantages are as follows: 1. having excellent transparency and smoothness, good display effect. 2. Surface decorative performance, may be surface-treated printing, easy to suppress pattern, easy metal processing (vacuum metallization layer) 3. good mechanical strength. 4. good barrier properties to oxygen and water vapor. 5. good chemical resistance, can withstand the erosion of a variety of chemical substances. 6. Non-toxic, health performance reliable, available to food, drugs and medical equipment packaging, and can be packaged their Y-ray sterilization items. 7. Good environmental adaptability, can be economically and easily recycled; its waste incineration, does not produce harmful substances harm the environment. PET sheet is considered to be in line with (ROSH) environmental requirements of an ideal packaging material.
