<p>A polyvinyl alcohol alloy is provided, which consists essentially of about 5wt% ~ about 94.99wt% of polyvinyl alcohol homopolymer, about 75wt% ~ about 5wt% of polyamide, 0.01wt% ~ about 20wt% of heatstable inhibitor and 0 ~ about 20wt% of conventional additives chosen from plasticizer, light stabilizer and/or antioxidant. The polyvinyl alcohol alloy is suitable in the manufacture of high barrier product, such as multilayer co-extruded high barrier films or sheets, and the film has an air permeability in 24 hours of less than about 20 cm3/m2·24h·0.1MPa as measured by differential pressure measurement according to GB/T1038-2000.</p> |
