Embodiment Construction

[0016] A food packaging paper, made of the following components by weight, 6 parts of glycerin, 30 parts of goosegrass, 30 parts of bermudagrass, 25 parts of knotweed, 30 parts of waxy cornstarch, 4 parts of citric acid ester; It is made with the following crafting steps:

[0017] 1) Wash goosegrass, bermudagrass and knotgrass, soak in 10% sodium carbonate solution for 1-2 days, filter and wash, then add 150-200 parts of water and 6 parts of carbonic acid Sodium hydrogen, after stirring evenly, decoct for 1-1.5 hours, stop the fire, and cool to room temperature;

[0018] 2) Add 0.1 parts of enzymolysis solution to 1), and stir evenly for 3-4 hours. The enzymolysis solution contains 0.2% alkaline protease and 0.1% carboxypeptidase B, and the protein in the mixture is hydrolyzed, and the remaining Part of it can improve the flocculation ability of pulp and enhance the toughness of paper;

[0019] 3) Add 60 parts of water, 1 part of sodium hydroxide and 5 parts of sodium chlori...

Abstract

The invention discloses food packaging paper. The food packaging paper is characterized in that the food packaging paper is prepared from glycerin, eleusine indica, cynodon dactylon, equisetum ramosissimum, waxy corn starch and citrate. The food packaging paper has the advantages that raw material sources are wide, reaction is mild, the food packaging paper is free of toxin and environmentally friendly, and the food packaging paper accords with the 'green chemistry' concept of a modern requirement. The food packaging paper is environment-friendly and safe food packaging paper. The raw materials are easy to obtain, operation is easy, cost is low, and the food packaging paper is economical and environmentally friendly. By means of paper pulp raw materials made by processing eleusine indica, cynodon dactylon, equisetum ramosissimum and waxy corn starch, paper forming strength is high, flexibility is good, the paper is not prone to breakage, the application range is wide, the smoothness and the printing adaptability are high, inking of the packaging paper can be more uniform, the food packaging paper is suitable for printing of various surfaces and can be completely degraded, and the packaging paper is good in moisture resistance.

Description

technical field [0001] The invention relates to the field of paper production, in particular to a food wrapping paper. 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 added to the pulp. The migration of harmful components of some chem...
