Problems solved by technology

[0002] Paper manufacturing needs to consume a lot of wood, which puts a lot of pressure on the ecological environment. The consumption of food packaging paper is also quite huge, and now food packaging paper is basically made of common paper, and there is no obvious classification of food packaging special paper. , but these papers generally contain chemical additives commonly used in papermaking such as brighteners, sizing agents, waterproofing agents, etc., and microbial pollution is also relatively serious, which does not meet the requirements of health, sanitation, environmental protection and conservation

Embodiment 1

[0023] A preparation method of environment-friendly food packaging paper, comprising the following steps:

[0024] A. Grind 100kg of dry rice straw into 20-40 mesh coarse powder with a tooth cutter;

[0025] B, get 20kg sterile water and the dry rice straw powder that step A gains is ground into can pass through 40 purpose rice straw pulp with refiner together, then steam 20min with steam 125 ℃;

[0026] C. Mix 20kg of sterile water with 4kg of pullulan, 1kg of coagulated polysaccharide and 0.18kg of glucomannan to form a colloidal slurry, then mix it with the straw pulp obtained in step B, and then grind it with a colloidal mill Once, make the slurry mix more fully;

[0027] D. The film obtained in step C is formed into a film by the film-forming equipment, and the film is immediately heated and solidified in a box full of steam. The heating time is 4 minutes, and then sent to the drying tunnel furnace for drying, cutting, packaging, and production. An environment-friendly ...
