Environmentally friendly thermal insulation type composite thermal insulation packing material

Abstract

The invention discloses environmentally friendly thermal insulation type composite thermal insulation packing material. The material comprises 10 to 22 percent of cellulose, 5 to 8 percent of protein cellulose, 25 to 35 percent of casting polypropylene, 5 to 10 percent of starch, 10 to 15 percent of chitose, 8 to 15 percent of xylan, 5 to 15 percent of mannan, 1 to 3.5 percent of a coupling agent, 2 to 5 percent of an antioxidant, 10 to 20 percent of a surface active agent, and 2 to 5 percent of a solubilizer; a heat insulation layer is made of a medium temperature heat insulation material layer; a biological degradation layer and the heat insulation layer are formed through hot compression. By adopting the mode, the material adopts the combination of the degradable layer and the heat insulation layer, improves the heat insulation performance and the biodegradability, meanwhile improves the tenacity of products as various of assistant is added, has high tensile property, and can be applied to packing of various products with high requirements on thermal insulation performance.

Description

technical field

[0001] The invention relates to packaging materials, in particular to an environment-friendly and heat-insulating composite thermal insulation packaging material. Background technique

[0002] Packaging materials are indispensable materials in industry, agriculture and household, and plastic packaging is one of the four major materials in the packaging industry: paper and cardboard account for 30%, plastics account for 25%, metal accounts for 25%, and glass accounts for 15%. The above two 25% fully illustrate the importance of the plastic packaging industry. Although the plastic packaging industry is the second packaging material, its practicality is not as good as that of paper and cardboard packaging. But the plastic packaging industry is growing at a rate of 5% per year, and it's safe to say, even in the countries where plastic packaging gets the most blame. Plastics will continue to develop at a much faster rate than other packaging materials, because m...
