Modified PVA coated composite film

The modified polyvinyl alcohol coated composite film is colorless and has good transparency. It has excellent oil resistance and organic solvent resistance. It has good antistatic properties. It can be used for microwave heating and metal detection of packaged food. It has excellent aroma preservation performance, which can maintain the original flavor of the food in the bag for a long time, and at the same time effectively prevent the odor outside the packaging material from entering the packaging bag.   It has excellent barrier properties for oxygen, nitrogen, hydrogen and carbon dioxide. Its oxygen barrier performance is better than that of PVDC coated film and EVOH five-layer co-extruded film. Its oxygen barrier performance is the best among various resin films, comparable to aluminum foil, glass, aluminum oxide-plated film and silicon oxide-plated film.   The production cost of PVA coated composite film is much lower than that of paper-aluminum-plastic composite and aluminum-plastic composite packaging materials, much lower than that of EVOH five-layer co-extruded film, and lower than that of composite film with PVDC coating.   Satisfactory results can be achieved by using the existing dry laminating machines, coating machines, wet laminating machines, extrusion laminating machines and other equipment of various flexible packaging manufacturers. The modified PVA glue does not form a skin, and the viscosity does not increase significantly during normal use. The coating layer is very thin, but the thickness uniformity of the coating remains excellent.   The structural components of polyvinyl alcohol (PVA) high barrier water-based coating liquid are carbon, oxygen, hydrogen and silicon. It is degradable and recyclable. When burned, it only produces carbon dioxide and water without producing other substances harmful to the environment and human health. It is pollution-free and is an ideal environmentally friendly high barrier packaging material.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.
