Abstract

The invention provides a drink packaging material and a preparation method thereof. The drink packaging material is prepared from the following raw materials in parts by weight: 20-45 parts of polyvinylidene chloride, 10-50 parts of PA66, 15-30 parts of polyvinyl alcohol, 10-25 parts of polyethylene glycol, 5-15 parts of polyglycolic acid, 5-12 parts of corn starch, 3-15 parts of anti-oxidant, 4-10 parts of sea-foam stone powder, 5-9 parts of sodium aliphatate, 4-7 parts of calcium carbonate, 2-5 parts of graphene and 1-2 parts of diatomite. Compared with the prior art, the drink packaging material has the advantages that the plastic performance and the mechanical property are excellent, the preparation method is simple and feasible, and the drink packaging material is suitable for large-scale industrial production; and the drink packaging material is effectively bio-degradable, has the degradation rate of 80% or above, is free from environmental pollution and can be applied to the drink food field.

Description

technical field [0001] The invention belongs to the technical field of plastic products, and in particular relates to a packaging material for drinks and a preparation method thereof. Background technique [0002] Beverages need to be packaged for sale, and packaging materials are divided into glass products, metal products, and plastic products. According to different types of beverages, corresponding packaging materials can be selected. At present, plastic packaging materials are widely used. Polyethylene plastic packaging products in plastic materials are disposable packaging products with low prices and are widely used in daily life. Because there is basically no recycling value, the recovery rate is extremely low. Because of its light weight and non-degradable characteristics, it drifts with the wind, pollutes the land and water, and accounts for the main part of the white garbage that has formed in our country. At present, my country has explicitly banned the produc...
