Classification Logic: Dual Dimensions of Material and ProcessThe classification system of plastic films centers on polymer materials, forming a multi-level technical map by combining molding processes and functional characteristics. The current mainstream classification covers eight major substrate

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
