Yiwu famous packaging materials plant Tips: Yiwu famous factory specializing in the production of packaging materials POF shrink film / heat shrinkable bags, PVC shrink film / heat shrinkable bags, a variety of customized flat bags, round bags, plastic bags. PVC shrink film is a contraction rate of more than 40% of shrink film, roll color pale blue, opened transparent for product packaging, played the role of dust and moisture. Compared to other materials shrink film, PVC shrink film for its high transparency, hair dryer blowing and shrinkage characteristics highly welcomed by the market. POF5 layer coextruded shrink packaging film is based on PE and PP as main raw materials by coextrusion blow molding processing and production of a multilayer heat shrinkable packaging material nontoxic. Early 1990s from Italy, the main features of the product are: 1, high transparency, good gloss, can clearly show appearance, improve sales results reflect higher commodity grade plus. 2, flexible, easy to use. Because of this flexibility of the packaged goods can be buffered when subjected to an external impact, but also for the packaging containers to prevent brittle crushing containers scattering. 3, a large shrinkage. Highest shrinkage rate of 75%, using the force of contraction flap its high shrinkage produced a set of items to be packaged can bind tightly, play a good role in bundling, ideal for packaging multiple items in the collection, especially for special-shaped packaged goods very good effect. And after a contraction of POF-C5 film special process controllable, to meet the different requirements of commodities on the contractile force. 4, good weld sealing performance, high strength, suitable for manual, semi-automatic and high speed automatic packaging. 5, cold, and can maintain flexibility at -50 degrees Celsius and not stiff brittle, suitable packing material stored in a cold environment and transport. 6, environmentally friendly non-toxic. POF-C5 main raw material include a heat-shrinkable packaging film LLPET, PP, PPC and the necessary functional additives, such as slip agents, antiblocking agents, antistatic agents are non-toxic materials. PDA meets U.S. standards, packaged food. 7, good barrier properties, excellent moisture and dust properties. 8, lower packaging costs, better than cartons and other packaging materials. Shrink film uses: (1) major in lactic acid bacteria drinks, jelly, pudding, noodles and other food bowl skin packaging (2) drugs, health products, telecommunications equipment (MP3, DVD, batteries, meters, switches, telephones, fax machines, etc.); (3) Daily stationery - books, brush, toys and other packaging or collection of packaging, crafts - Frame - Glass packaging; (4) daily - pesticides, cosmetics, video products and other packaging.
