The environment-friendly freshness protection bag is composed of a breathable protective layer and a freshness protection membrane. An observation window is arranged on the breathable protective layer. The freshness protection membrane comprises, by weight, 35% to 60 % of polyethylene resin, 2% to 8% of light calcium carbonate, 0.1% to 1.5% of sodium alga acid, 0.5% to 3% of chitosan, 5% to 25% of casein, 15% to 35% of Arabic gum, 0.05% to 1% of an anion antibacterial agent, 0.1% to 15% of epoxidized soybean oil, and the balance beeswax. The environment-friendly freshness protection bag has the advantages that the breathable protective layer is made of environment-friendly materials, repeated use can be achieved, degradation can be achieved after the freshness protection bag is used and scraped, environment is free of pollution, the freshness protection membrane on the inner wall of the breathable protective layer is good in breathability and long in freshness protection time, and after food in the freshness protection bag for a long time is taken out, the food is not harmful to a person who eats the food.
Description
Technical fieldThe present invention relates to a kind of environmental protection freshness protection package, belong to fresh-keeping apparatus technical field.
Background technologyFreshness protection package is the plastic packing product of the class fresh-keeping foodstuff commonly used of people, in people's daily life now, a lot of places all be unable to do without it, mainly refer to the sack that is mainly used in other foods such as preservation vegetables, fruit, cereal, prepared food with the food fresh keeping film production, use in daily life very extensive.From physical angle, freshness protection package has oxygen permeability and the moisture permeability of appropriateness, regulates by oxygen content and moisture around fresh-keeping product, intercepts koniology, thereby extends the freshness date of food.Freshness protection package is divided into the kinds such as polyethylene (PE), polyvinylchloride (PVC), polyvinylidene chloride (PVDC) by making material.PE, PVDC freshness protection package are relatively safe, and PE is mainly used in the packing of fruit, vegetables etc., and PVDC is mainly used in the packing of some prepared food, ham etc.Although and the PVC freshness protection package is widely used in the external packing of food, vegetables etc., and human body is had certain potential hazard.Its harm is mainly derived from two aspects: the one, and vinyl chloride monomer residual quantity in product (vinyl chloride is less than 1mg/kg to the threshold limit values standard of human body), the 2nd, the contamination of the processing aid that uses in the course of processing.Two kinds of carcinogenic possibilities of material tool are arranged, the one, VCM(vinyl chloride monomer in PVC), the one, DEHA(plasticizer), if the composition of VCM 1PPM(1,000,000/) scope in be nontoxic, if exceed standard, carcinogenic possibility is just arranged; , and plasticizer at high temperature can discharge and harmful.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide a kind of good permeability, fresh keeping time length and harmless environmental protection freshness protection package.
For achieving the above object; the technology used in the present invention solution is: a kind of environmental protection freshness protection package; it is characterized in that: formed by ventilative protective cover and preservative film; be provided with an observation window on ventilative protective cover; each constituent mass ratio of described preservative film is: poly-vinyl resin, 35%-60%; precipitated calcium carbonate, 2%-8%; sodium alginate, 0.1%-1.5%; shitosan, 0.5%-3%; casein, 5%-25%, Arabic gum, 15%-35%, anion antiseptic, 0.05%-1%; epoxidized soybean oil, 0.1%-15%, surplus is beeswax.
Described ventilative protective cover is to be made by environment-friendly materials.
A kind of environmental protection freshness protection package, its beneficial effect is: ventilative protective cover is to be made by environment-friendly materials, can Reusability, use and can degrade after scrapping, environmentally safe; Edible after preservative film ventilation performance on ventilative protective cover inwall is good, fresh keeping time long and long-time fresh-keeping food takes out in this freshness protection package the people is safe from harm.
