Polyethylene (PE), as the synthetic plastic with the largest global production, is composed of long-chain hydrocarbons formed by the polymerization of ethylene monomers. The high tunability of its molecular structure—ranging from linearly arranged High-Density Polyethylene (HDPE) to branched Low-Den

Technical Definition and Core ValuePVC heat shrink film is a functional packaging material primarily made from polyvinyl chloride (PVC) resin, produced through extrusion blowing and(oriented stretching) processes. Its core value lies in the "memory effect" of thermally activated molecular chains: wh

The Essence of the Technology: From Uniform Coating to Micron-level Control Gravure coating technology is a process that achieves precise transfer of coatings through the micro-cavity structure on the surface of a gravure roller. Its core lies in using a metal roller engraved with regular geometric

Technical Essence: The Molecular Revolution of Elasticity and Environmental ProtectionTPU (Thermoplastic Polyurethane) film is a high-performance material realized through molecular design of polyester/polyether segments and isocyanates. Its core value lies in integrating the elasticity of rubber wi

Industry Background: From Traditional Manufacturing to Sustainable InnovationAs the "invisible skeleton" of modern industry, rubber products, with their high elasticity, wear - resistance and sealing properties, have penetrated into core fields such as automotive, medical, aerospace and construction
