Welcome to exchange and study together.

PE shrink film is mainly prepared from the following formula: ethylene vinyl acetate copolymer, poly-3-hydroxybutyrate, high density polyethylene, linear low density polyethylene, antioxidant, heat stabilizer, flame retardant, lubricant, opening agent and plasticizer. The utility model is characterized in that the thickness of the resin film is 0.04 ~ 0.25mm and the width is 100 ~ 3000mm; The longitudinal shrinkage rate is 50 ~ 85%, and the transverse shrinkage rate is 5 ~ 60%; The transverse contraction force is 0.2 ~ 0.8n/cm and the longitudinal contraction force is 0.5 ~ 2.0n/cm; Each of the three resin films contains a variety of different components and mass percentages, such as pe33 00~100.00,EVA0. 00~11.00,PP0. 00 to 50, anti-aging masterbatch 0 to 12, antistatic masterbatch 0 to 14. The anti-aging masterbatch is made up of 60 LLDPE of quality, 30 parts of LDPE, 0.08 parts of quality antioxidant 1010, 10 parts of titanium white powder and 10% quality polyethylene wax. Through the cooperation between these raw materials, the surface has good gloss, easy degradation, will not pollute the environment, the preparation method is simple and easy to operate, and can realize large-scale production. The surface has good gloss, easy degradation, no pollution to the environment, simple preparation method and easy operation, and can realize large-scale production

expand data:
1. Primary protection. Primary protection provides the surface protection of the product, forming a very light and protective appearance around the product, so as to achieve dust-proof, oil-proof, moisture-proof, waterproof and primary protection, and provide the surface protection of the product
2. Cost saving. The use of winding film for product packaging can effectively reduce the use cost. The use of winding film is only about 15% of the original box packaging. The use of winding film for product packaging of 35% of heat shrinkable film can effectively reduce the use cost
3. Compression fixation. With the help of the retraction force after the stretching of the winding film, the products are wound and packaged to form a compact unit without occupying space, so that the pallets of the products are tightly wrapped together, which can effectively prevent the mutual dislocation and movement of the products during transportation. At the same time, the adjustable stretching force can make the hard products close to each other and tighten the soft products, Especially in the tobacco industry and textile industry, it has a unique packaging effect
4. PE heat shrinkable film is a kind of surface protective film. It can be used to wind goods and reduce the wet damage caused by rain to the packaging of goods to a certain extent. As an environmentally friendly packaging material with low cost, high production efficiency, excellent appearance and efficient logistics, PE heat shrinkable film has been widely used in the field of beverage and beer in developed countries, and has been increasingly widely used in China’s beverage and beer industry

the common raw material is LDPE heavy packing, and the melting index is 0.3; If you want to add linear material, you can use the of melt finger 1; Domestic materials include 2100 in Qilu, 1810D in Yangba and Maoming, 2420d in CNOOC and shell, etc; Foreign materials: 0300 of South Korea; 3003 in Qatar, etc
welcome friends who produce PE heat shrinkable film to come in and discuss
welcome friends who need PE heat shrinkable film production process to come in and ask questions.


domestic material Qilu 2100

I want to make the horizontal ratio into the vertical ratio. How should I match the vertical ratio into the horizontal ratio?

the number of LDPE, LLDPE and melt index
