Abstract

The invention relates to an antimicrobial plastic wrap, which is made by the following raw materials in parts by weight: 80-100 parts of low density polyethylene resin, 7-15 parts of linear low density polyethylene resin, 1-4 parts of nano titanium dioxide, 8-15 parts of calcium carbonate superfine powder, 2-6 parts of epoxy soybean oil, 0.1-0.5 parts of an antioxidant, 3-7 parts of polyethylene glycol, 4-10 parts of medical stone, and 2-4 parts of sodium silicate. The polyethylene resin is used as the base material, and the nano titanium dioxide as antimicrobial agent is added, so that the antimicrobial plastic wrap is suitable for such as vegetables and fruits with high antimicrobial requirements. The antimicrobial plastic wrap contains the calcium carbonate superfine powder, and easily degrades, and has little pollution on environment, so that the plastic wrap is green and environmentally friendly.

Description

A kind of antimicrobial preservative film
Technical field
The present invention relates to fresh-keeping apparatus technical field, specifically a kind of antimicrobial preservative film.
Background technology
Preservative film preservative film is the plastic packing product of the class fresh-keeping foodstuff commonly used of people, and people are daily now
In life, a lot of places all be unable to do without it, such as: food in microwave oven heating can be used, and in refrigerator, storing food can be used equally.Most preservative films of selling are in the market all to take ethene masterbatch as starting material, according to the different sorts of ethene masterbatch, preservative film can be divided into three major types: the first is polyethylene, be called for short PE, this material is mainly used in the packing of food, this film that the fruit that we buy usually, vegetables are used, be included in supermarket purchase the work in-process of returning all use be this material; The second is polyvinyl chloride, is called for short PVC, and this material also can be for food product pack, but it has a certain impact to the security of human body, because production technique needs, PVC fresh-preserving film is in making processes, can add a large amount of softening agent, the fluidizer of namely often saying.Softening agent is insoluble to cold water, but more than 60 degree Celsius, or will dissolved in grease out; The third is polyvinylidene dichloride, is called for short PVDC, is mainly used in the packing of the products such as some prepared food, ham.From physical angle, preservative film has appropriate oxygen-permeable and Water Vapour Permeability, regulates by fresh-keeping product oxygen content and moisture content around, intercepts koniology, thereby extends the freshness date of food.
Summary of the invention
The object of the present invention is to provide a kind of antimicrobial preservative film.
Object of the present invention can be achieved through the following technical solutions:
A kind of antimicrobial preservative film, it is characterized in that, it is comprised of the component of following weight part: ldpe resin 80-100 weight part, type low density polyethylene resin 7-15 weight part, nano titanium oxide 1-4 weight part, calcium carbonate superfine powder 8-15 weight part, epoxy soybean oil 2-6 weight part, oxidation inhibitor 0.1-0.5 weight part, polyoxyethylene glycol 3-7 weight part, medical stone 4-10 weight part, water glass 2-4 weight part.
It is comprised of the component of following weight part: ldpe resin 90 weight parts, type low density polyethylene resin 11 weight parts, nano titanium oxide 3 weight parts, calcium carbonate superfine powder 12 weight parts, epoxy soybean oil 4 weight parts, oxidation inhibitor 0.3 weight part, polyoxyethylene glycol 5 weight parts, medical stone 7 weight parts, water glass 3 weight parts.
The particle diameter of described calcium carbonate superfine powder is 5-15 μ m.
