Using flaxen fiber Fresh-keeping Packaging for Fruits and Vegetables bag of the present utility model, its advantage is：
1. fruits and vegetables preservation effect is good.It is preferable except one side has to fruits and vegetables with the fibrilia net of environment-friendly type slurry bonding
Protective action, the loss of moisture is prevented, on the other hand, there is certain gas permeability again, certain gas can occur with extraneous
Exchange, and prevent condensation of the vapor in packaging bag, so as to maintain fresh-keeping environments good in packaging bag.In addition, with shell
Glycan particularly with antibacterial overcoat made of low-molecular weight chitoglycan, has preferable permeability and bactericidal effect, and can
To prevent fruits and vegetables from changing colour, while also delay fruits and vegetables tissue aging to a certain extent, further enhancing fresh-keeping effect.
2. natural environmental-protective is pollution-free.All it is to make the raw material of flaxen fiber Fresh-keeping Packaging for Fruits and Vegetables bag of the present utility model
Degradable environment friendly material, if flaxen fiber is pure natural string, chitosan mainly extracts from the crustacean of ocean, gathers
Vinyl alcohol is a kind of healthy material that can be used for human body, and these materials are all safe to the human body harmless, and under natural environment all
Can be with complete biodegradable so that flaxen fiber Fresh-keeping Packaging for Fruits and Vegetables bag of the present utility model be natively provided with foodsafety and
Environment friendly.

Embodiment
The utility model embodiment provides a kind of flaxen fiber Fresh-keeping Packaging for Fruits and Vegetables bag, to solve existing Fresh-keeping Packaging for Fruits and Vegetables
The problem of bag.
In order that those skilled in the art more fully understand the technical scheme in the utility model, below in conjunction with this reality
With the accompanying drawing in new embodiment, clear, complete description is carried out to the technical scheme in the embodiment of the utility model, it is clear that
Described embodiment is only the utility model part of the embodiment, rather than whole embodiments.Based on the utility model
In embodiment, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, it should all belong to the scope of the utility model protection.
Fig. 1 is refer to, Fig. 1 is the flaxen fiber Fresh-keeping Packaging for Fruits and Vegetables bag schematic cross-sectional view that the utility model embodiment provides,
Its bag of body material includes three-layer structure from outer to inner, is followed successively by fish tail and waterproof layer 1, flaxen fiber stratum reticulare 2 and antibacterial overcoat 3.Its
In, flaxen fiber stratum reticulare 2 is basic unit, by flaxen fiber in a jumble staggeredly according to using environment-friendly type after non-woven fabrics dry-laying process networking
Slurry, as polyvinyl alcohol pulp, converted starch glue or polyvinyl alcohol and converted starch mixed slurry bonding after again drying and
Into with the increase of thickness, the increase of bag body intensity, but cost also increases, and its thickness can be taken into account when between 0.5mm-1mm
Bag body intensity and cost of material.The flaxen fiber that can be used to use includes ramee, tossa, bastose, other crudefiber crops
String, such as hemp, flax, bluish dogbane are also used as Fresh-keeping Packaging for Fruits and Vegetables bag of the present utility model including cotton.It is anti-
Water conservation layer 1 is permeable watertight film, and by organic fluoride class high score polymer, the cationic such as pH 2-4, concentration 3-5% is organic
