Abstract

The invention relates to a high-oxygen resistant steaming-resistant polyvinylidene chloride coating film and a manufacturing method thereof. The high-oxygen resistant steaming-resistant polyvinylidene chloride coating film comprises a base, a coating layer on the surface of the base, and a base glue layer between the coating layer and the base. The coating layer is a coating obtained by coating modified high-oxygen resistant steaming-resistant polyvinylidene chloride latex. The modified high-oxygen resistant steaming-resistant polyvinylidene chloride latex comprises: by weight, 30 to 38% of a high-oxygen resistant steaming-resistant polyvinylidene chloride blended emulsion, 1.5 to 6% of a nano-material filler, 1 to 8% of a slip agent, 0.1 to 5% of an abherent and 5 to 60% of softened water. The high-oxygen resistant steaming-resistant polyvinylidene chloride blended emulsion comprises: by weight, 40 to 94% of a vinylidene chloride monomer, 1.5 to 10% of an acrylate, 1 to 6% of one or more of acrylic acid and acrylonitrile, 0.5 to 2% of an initiator, 0.1 to 0.8% of an emulsifier, 0.5 to 1% of a stabilizer and 0 to 55% of soft water.

Description

Technical field [0001] The invention relates to a polyvinylidene chloride coating film with high oxygen resistance and cooking resistance and a manufacturing method thereof, belonging to the field of new polymer materials. Background technique [0002] Glass bottles and metal filling have been the main way of food storage for a long time in the past. In 1958, the soft can packaging developed by the United States successfully replaced tinplate cans, and commercialized large-scale production began. Since 1968, Japan began to use high-temperature cooking For bag-packed curry food, rice, meatballs, etc., high-temperature cooking and sterilization has become a common method to extend the shelf life of food. Problems such as bag swelling, bag breaking, odor, delamination, surface wrinkling, curling, air leakage, and pinholes have caused quality disputes. At present, in the selection of high-temperature retort bag materials, in addition to solving the above problems, safety and en...
