Iodine in salt can only be biologically active in the human body when it is transformed into iodide ions, and iodide is extremely unstable, easy to decompose, volatilize and lose efficacy
In addition, edible salt is easy to absorb moisture, so it has higher requirements for packaging bags.

Abstract
The invention discloses inner film of an edible salt packaging bag, and relates to the technical field of plastic film. The inner film is prepared from, by weight, 40-50 parts of low-density polyethylene, 10-15 parts of ultralow-density polyethylene, 10-15 parts of kieselguhr, 8-12 parts of polyoxyethylene, 6-10 parts of carbomer resin, 5-8 parts of maltodextrin, 4-6 parts of gelatin, 4-6 parts of a toughening agent, 3-5 parts of glycerin monostearate, 3-5 parts of epoxy rice bran oleic acid butyl ester, 2-3 parts of beewax, 2-3 parts of polyoxypropylene glycerol ether, 1-2 parts of calcium sulphate dihydrate and 1-2 parts of nano-zinc oxide. The inner film is not only significant mechanical property but also good in stability, on one hand, the inner film does not generate any reaction with ingredients in edible salt, on the other hand, the inner film has the excellent sodium chloride permeation resistance and sealing property to prevent the edible salt from being deteriorated due to the fact that the edible salt makes contact with air, and therefore the eating quality and the eating safety are guaranteed.
Description
Technical field: [0001] The invention relates to the technical field of plastic films, in particular to an inner film of an edible salt packaging bag. Background technique: [0002] Edible salt is iodized salt made by adding a certain amount of iodine to refined salt, crushed washing salt, and solar salt. Iodine in salt can only be biologically active in the human body when it is transformed into iodide ions, and iodide is extremely unstable and easy to decompose, volatilize and become ineffective. In addition, edible salt is very easy to absorb moisture, so it has higher requirements for packaging bags. At present, the packaging of edible salt is generally made of paper bags, but a layer of film must be attached inside the paper bag. On the one hand, it is to improve the toughness of the packaging bag and avoid the easy breakage of the simple paper bag packaging; on the other hand, it is to enhance the sealing. To make up for the limitation of paper bag sealing. Inventi...
