[0002] A composite film refers to a film with a multi-layer structure formed by combining various plastics with paper, metal or other materials through processes such as lamination extrusion laminating and co-extrusion molding. The materials of the composite film include any possible material combinations, such as covering a ceramic film on a metal oxide or covering an aromatic polyamide film on a polysulfone microporous membrane. Its flat film or spiral wound membrane needs to be reinforced with a non-woven fabric to support the pressure resistance of the microporous membrane, while the hollow fiber membrane does not.
