Abstract
The invention discloses a kind of antibacterial fresh-keeping packaging bag, in parts by weight, it is made up of 90 100 parts of ldpe resin, 7 15 parts of type low density polyethylene resin, 14 parts of nano titanium oxide, 25 parts of citric acid, 26 parts of zeins, 8 15 parts of methyl methacrylate, 0.1 0.5 parts of antioxidant, 37 parts of polyethylene glycol, 4 10 parts of glass fibre, 14 parts of rosin resin.Invention additionally discloses the preparation method of above-mentioned antibacterial fresh-keeping packaging bag.Because present invention uses ldpe resin, good with other materials compatibilities, the antibacterial fresh-keeping packaging bag of gained has intensity height, while has the performance of insect prevention and antibacterial, without worrying the infringement of bacterium and insect to material inside antibacterial fresh-keeping packaging bag, closer to the life of people.
Description
Technical field
The present invention relates to plastic packaging bag manufacture field, and in particular to a kind of antibacterial fresh-keeping packaging bag and preparation method thereof.
Background technology
Fresh-keeping packaging bag is the plastic packing product for a kind of fresh-keeping foodstuff that people commonly use, now with many families all from not
Open them.Food in microwave oven heating can use, and food is deposited in refrigerator can equally use, and people are mainly using freshness protection package
Prevent the erosion of dust and bacterium to food.The most fresh-keeping packaging bags and conventional polybag sold in the market
Equally, all it is using ethene masterbatch as raw material, according to the variety classes of ethene masterbatch, fresh-keeping packaging bag can be divided into three major types：The
One kind is polyethylene, abbreviation PE, and this material is mainly used in the packaging of food, the water fruits and vegetables bought usually this
Fresh-keeping packaging bag, be included in supermarket buying return semi-finished product all be this material；Second is polyvinyl chloride, referred to as
PVC, this material can be used for packaging for foodstuff, but its security to human body has a certain impact；The third is poly- inclined two
Vinyl chloride, abbreviation PVDC, it is mainly used in the packagings of the products such as some prepared food, ham.In these three freshness protection packages, PE and PVDC this two
The fresh-keeping packaging bag of kind of material be to human body it is safe, can be with safe to use, and PVC fresh-keeping packaging bags contain carcinogen, it is right
Human body harm is larger.From physical angle, fresh-keeping packaging bag has appropriate oxygen permeability and moisture permeability, adjusts by fresh-keeping product week
The oxygen recipe ingredient and moisture recipe ingredient enclosed, the dust in air is obstructed, so as to extend the freshness date of food.Prior art
Some defects be present in middle antibacterial fresh-keeping packaging bag：1st, some antibacterial fresh-keeping packaging bag insufficient strengths, easily cause tearing for packaging bag
Split, just do not have the effect of packaging；2nd, the antibacterial fresh-keeping packaging bag also having can not meet the requirement of antibacterial.
The content of the invention
It is an object of the invention to provide a kind of high, the of good preservation effect antibacterial fresh-keeping packaging bag of intensity and its preparation side
Method.
Above-mentioned purpose is achieved through the following technical solutions：
A kind of antibacterial fresh-keeping packaging bag of the present invention, in parts by weight, is made up of following raw materials according：Ldpe resin
90-100 parts, type low density polyethylene resin 7-15 parts, nano titanium oxide 1-4 parts, citric acid 2-5 parts, the molten egg of corn alcohol
White 2-6 parts, methyl methacrylate 8-15 parts, antioxidant 0.1-0.5 parts, polyethylene glycol 3-7 parts, glass fibre 4-10 parts, pine
Botany bar gum 1-4 parts.
The preparation method of above-mentioned antibacterial fresh-keeping packaging bag, its preparation method are：Low density polyethylene (LDPE) is taken using said ratio
It is resin, type low density polyethylene resin, nano titanium oxide, citric acid, zeins, methyl methacrylate, anti-
Oxygen agent, polyethylene glycol, glass fibre, rosin resin, melted, be kneaded by extrusion or extrusion blow moulding technique, being extruded, be cold
But, dry, after pelletizing, blown film, bag produce antibacterial fresh-keeping packaging bag.
Take after above-mentioned technical proposal due to present invention uses ldpe resin, with other materials compatibilities
Good, the antibacterial fresh-keeping packaging bag of gained has intensity height, while has the performance of insect prevention and antibacterial, without worrying bacterium and insect
Infringement to material inside antibacterial fresh-keeping packaging bag, closer to the life of people.
The embodiment of form by the following examples, the above of the present invention is remake further specifically
It is bright, but the scope that should not be construed as the above-mentioned theme of the present invention is only limitted to following embodiment, it is all to be based on the above institute of the present invention
The technology of realization belongs to the scope of the present invention.
