Oxygen outstanding performance: (1) the resistance of modified polyvinyl alcohol (PVA) coating composite membrane for oxygen, nitrogen, hydrogen and carbon dioxide has excellent barrier property of the oxygen resistance performance is better than that of PVDC (polyvinylidene chloride) thin film, coating is better than that of EVOH (ethylene - vinyl alcohol copolymer) five layers co-extrusion film. Its oxygen resistance performance is the best of the various kinds of resin film, with aluminum foil, glass, with aluminum oxide film and silicon oxide film plating. SHRINK BARRIER BAGS


(2) low cost: the polyvinyl alcohol (PVA) coating composite film production cost is much lower than paper lu: su composite, lu: su composite packaging materials production cost, far lower than
