1. PVC sheet has high toughness, is not easy to burn, generates chlorine gas when burning, and has certain influence on the environment. PVC is easy to heat, can be sealed by sealing machine and high frequency sealing, and is the main raw material for producing transparent plastic products. PVC sheet is a widely used and popular material. PVC film can be divided into environmental protection and non-environmental protection. It can be made into transparent, colored, anti-static, gold-plated, flocked and other blister packaging products. Features: high transparency, good surface gloss, less crystal point, small water grain, wide application, strong impact resistance, and easy to shape. The products are widely used in toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery, etc. Product packaging.
2, Dayu food blister packaging PS hard film density is low, poor toughness, easy to burn, will produce styrene gas (hazardous gas) when burning, so it is generally used to produce a variety of industrial blister trays. PS sheet is a new type of environmentally friendly packaging material developed in the past few years. It is widely used in medicine, food, toys and electronics due to its excellent thermoforming performance, good environmental performance and hygienic performance.
3, PET hard film has good toughness, is a new type of material developed in the past few years. With its excellent toughness, high strength, high transparency, and recyclable recycling, it is easy to burn, does not produce harmful gases when burned, and is an environmentally friendly material that gradually bans PVC, but at a high price. It is suitable for high-grade plastic products. The blister bulbs in Europe and the United States generally require PET materials, but their high thermal melting point brings great difficulties to high-frequency packaging.
4, Dayu food blister packaging PETG material is to solve the problem of high thermal melting point of PET materials, people put a layer of PVC film on the PET surface, named PETG, but the price is higher. Mainly used in electronics, food, toys, color box window, collar, footwear packaging.
5, PP sheet with polypropylene resin as the main raw material, adding various process color masterbatch, toughening agent and brightener, after mixing, plasticizing extrusion, three-roll calendering, cooling, traction and winding process production. PP sheet has the characteristics of non-toxic, odorless, hygienic, high mechanical strength and good barrier properties, and can be used for packaging in industries such as industry, agriculture and fruit. The surface of the tray made of PP anti-slip sheet is smooth and beautiful, and is well received by users. PP sheet is also suitable for the packaging of high-resistant cold foods, such as ice cream boxes, dumpling boxes, dumpling boxes, etc.
