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. It cannot replace the synthetic polymer plastic film. The main reason is that the mechanical properties of the film are poor. The natural edible polymer material itself is hydrophilic, and its moisture resistance is limited. waiting for solution

Description

technical field [0001] The invention relates to a natural antiseptic edible food packaging 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 plasticizer are...
