The processing technology of laminated bags mainly includes blow molding, extrusion lamination, and coating. Blow molding is suitable for producing high-strength films, extrusion lamination can tightly bond films of different materials, and coating is used to add functional coatings to the film surface, such as antioxidant coatings or heat-stabilizing coatings.
Laminated bags are widely used in food packaging (such as snacks and frozen foods), pharmaceutical packaging (such as pharmaceuticals and medical devices), and industrial packaging (such as electronic products and chemical products). Their excellent barrier and protective properties make them the preferred material for high-end packaging.
