Problems solved by technology

[0004] At present, there are degradable food packaging films made of natural biological materials such as soybean protein for oily food packaging, but edible packaging is not widely used commercially and cannot replace synthetic polymer plastic films. Poor mechanical properties, natural edible polymer materials are hydrophilic, and their moisture resistance is limited. At the same time, problems such as packaging heat sealability and printability have yet to be resolved

Abstract

The invention provides a natural moistureproof degradable food packaging paper, which includes a fiber layer, a protein film layer, and a moistureproof liquid layer arranged between the fiber layer and the protein film layer. The invention also provides a preparation method of the natural moistureproof degradable food packaging paper. The natural moistureproof degradable food packaging paper is completely a green and safe food packaging supply, and has the characteristics of easily available raw materials, simple operation, low cost, economical efficiency and environmental protection, fully solves the contradiction between food packaging wastes and environmental protection and other problems, and has the advantages of high paper strength, good flexibility, difficult breaking and wide range of application.

Description

technical field [0001] The invention relates to a natural moisture-proof degradable food wrapping paper and a preparation method thereof, belonging to the technical field of the food industry. Background technique [0002] With the development of the food industry, there are more and more types of food packaging paper. The more common ones are cake paper, candy paper, vermicelli paper box, bread paper, biscuit paper box, ice cream outer packaging paper, among which waterproof and oil-proof food packaging Paper is very popular, but most of them use polymer compounds such as polystyrene, polyvinyl chloride, and polypropylene as coating materials. At the same time, these materials are not easy to degrade, difficult to recycle, produce toxic gases when burned, and endanger the ecological environment. features. In addition, in the production process, chemicals such as anti-seepage agent, sizing agent, bleaching agent, dyeing agent, stabilizer, ultraviolet absorber and plasticize...
