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

A kind of edible salt packaging bag inner membrance
Technical field:
The present invention relates to plastic sheeting technical field, be specifically related to a kind of edible salt packaging bag inner membrance.
Background technology:
Edible salt be purified salt, pulverize washing salt, evaporate brine day in add certain iodine preparation and make add iodine Salt.Iodine in salt is only transformed into iodide ion could play biological activity in human body, and iodide character Extremely unstable, easily decomposes, volatilizees and lost efficacy.It addition, edible salt easily moisture absorption, therefore it is to packaging Bag requires higher.At present, the packaging of edible salt typically uses paper bag, but can must enclose inside paper bag Thin film, partly in order to improve the toughness of packaging bag, it is to avoid simple use paper bag packing exists Cracky phenomenon；On the other hand it is to strengthen sealing, makes up the finiteness that paper bag seals.
Summary of the invention:
The technical problem to be solved is to provide a kind of safe to use, good airproof performance and can The edible salt packaging bag inner membrance of degraded.
The technical problem to be solved uses following technical scheme to realize:
A kind of edible salt packaging bag inner membrance, is made up of the raw material of following parts by weight:
Low Density Polyethylene 40-50 part, ultra-low density polyethylene 10-15 part, kieselguhr 10-15 part, poly- Ethylene oxide 8-12 part, carbomer 6-10 part, maltodextrin 5-8 part, gelatin 4-6 part, toughener 4-6 Part, glyceryl monostearate 3-5 part, epoxyfuoic-oleic 3-5 part, Cera Flava 2-3 part, polyoxypropylene Glycerin ether 2-3 part, calcium sulphate dihydrate 1-2 part, nano zine oxide 1-2 part；
Its preparation method is as follows:
(1) Low Density Polyethylene, ultra-low density polyethylene and gelatin are sufficiently mixed, in microwave frequency 2450 Microwave treatment 10min under MHz, power 800W, adds polyethylene glycol oxide and Cera Flava, after mix homogeneously Continue microwave treatment 5min, obtain material I；
(2) in kieselguhr, add carbomer, be heated to 60-65 DEG C of insulation mixing 10min, add increasing Tough dose, epoxyfuoic-oleic and nano zine oxide, continue to be heated to 80-85 DEG C of insulation mixing 10min, Obtain material II；
(3) material I and material II is sufficiently mixed, at 0-5 DEG C, then stands 30min, add Fructus Hordei Germinatus and stick with paste Essence, glyceryl monostearate, polypropylene glycerol aether and calcium sulphate dihydrate, by mixture after mix homogeneously Material adds banbury, proceeds in extruder again, melt extrude at 190-210 DEG C after banburying 10-15min, Through naturally cooling to room temperature after.
Described toughener is made up of the raw material of following parts by weight: PEG400 10-15 part, terpenes tree Fat 10-15 part, chlorosulfonated polyethylene 8-11 part, silica white 5-9 part, Petiolus Trachycarpi oil 4-7 part, polyethylene pyrrole Pyrrolidone 3-6 part, carboxymethyl chitosan 3-6 part, guar gum 2-4 part, disproportionated rosin 2-4 part, tristearin Acid calcium 1-2 part, its preparation method is: add PEG400 and chlorosulfonated polyethylene in terpene resin, First it is heated to 100-110 DEG C of insulation mixing 10min after being sufficiently mixed, adds guar gum and disproportionated rosin, Continue to be heated to 130-140 DEG C of insulation mixing 10min, after then naturally cooling to 50-60 DEG C, add silica white And polyvinylpyrrolidone, stand after 30min supersound process 15 under supersonic frequency 40kHz, power 50W Min, is eventually adding Petiolus Trachycarpi oil, carboxymethyl chitosan and calcium stearate, is sufficiently mixed uniformly.
The invention has the beneficial effects as follows: institute of the present invention made membrane is exclusively used in edible salt packaging bag inner membrance, not only Mechanical performance is notable, and good stability, do not occur with the composition in edible salt any reaction, On the other hand there is the permeability of resistance to sodium chloride and the sealing of excellence, prevent edible salt from sending out because of ingress of air Change matter, thus ensures edible quality and edible safety.
