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

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

Industry Background and Technological EvolutionAs core equipment for polymer material processing, plastic sheet extrusion machines convert raw materials such as polypropylene (PP), polyethylene (PE), and polystyrene (PS) into sheets through processes like extrusion, calendering, and casting. These s

Industry Background and Technical PositioningAs a functional polymer material, CPE (Chlorinated Polyethylene) breathable film is produced through the chlorination modification of polyethylene. It integrates high breathability, water resistance, and environmental protection, making it a core material
