PVC sheet high toughness, not easy to burn, combustion will produce chlorine gas, a certain impact on the environment, PVC is easy to heat sealing, can be used to sealing machine and high-frequency sealing, is the main raw material for the production of transparent blister products. PVC sheet is a widely used and popular material, PVC film can be divided into environmentally friendly and environmentally friendly two, can be made into transparent, color, anti-static, gold plating, flocking and other kinds of blister packaging products, which are characterized by high transparency, good surface luster, less crystal points, water lines, wide range of uses, impact resistance, and easy to form, the product is widely used in toys, food, electronic products, medicine, Electrical appliances, gifts, cosmetics, stationery and other products packaging.PS hard sheet low density, poor toughness, easy to burn, combustion will produce styrene gas (is a harmful gas), so it is generally used for the production of a variety of industrial blister trays.PS sheet is a new type of environmentally friendly packaging materials developed in the past few years, by virtue of its excellent thermoforming properties, good environmental protection and hygiene performance, widely used in medicine, food, toys, electronics. PS sheet is a new type of environmentally friendly packaging material developed in the past few years.
PET hard sheet with good toughness is a new material developed in recent years. With its excellent toughness, high strength, high transparency, as well as recyclable, easy to burn, burning does not produce harmful gases, is an environmentally friendly materials and gradually outlawed PVC, but the price is high. Suitable for high-grade blister products, Europe and the United States, the general requirements of the blister PET material, but its high melting point, to the high-frequency encapsulation has brought great difficulties. PETG material is in order to solve the problem of high melting point of PET material, people in the surface of the PET composite on a layer of PVC film, named PETG, but the price is a little higher. It is mainly used in electronics, food, toys, color box window, collar tray, footwear packaging and so on. The advantages are as follows: excellent transparency and finish, good display effect. Excellent surface decorative properties, can be printed without surface treatment, easy to press patterns, easy metal processing (vacuum plating metal layer) with good mechanical strength. Good barrier performance to oxygen and water vapor. Good chemical resistance, can withstand the erosion of a variety of chemical substances. Non-toxic, reliable hygiene performance, can be used for food, drugs and medical equipment packaging, and can be Y-ray sterilization of the items it packaged. Good adaptability to environmental protection, can be economically and conveniently recycled; incineration of its waste does not produce environmentally hazardous substances. This type of sheet is considered to be in line with (ROSH) environmental protection requirements of an ideal packaging materials.
