Description
Technical field
The utility model is related to package packing supplies field, relates generally to a kind of degradable preservative film for being used to pack fruits and vegetables.
Background technology
A kind of raw material is expressed on Manufactured another film in the processing of preservative film or will be Manufactured not of the same race
The film of class is mutually bonded to together and as plural layers, and this product is referred to as composite membrane.Most of material of composite membrane is
Plastics, but can also use paper, metal foil (being usually aluminium) or fabric etc..The basic demand of composite membrane is exactly to have good between layers
Good gluing is to ensure the overall mechanical properties of packaging.In addition, composite membrane is used for agricultural production and packaging for foodstuff, compound
Binder is used in the processing of film, the selection of its solvent and gluing technique etc. will meet corresponding sanitary standard requirement.Mesh
The utilization of preceding preservative film is than larger, so after preservative film is finished, and processing is a very big problem, therefore design environmental protection at present
Preservative film, realizes and the close friend of environment is treated.
Utility model content
The problem of for current preservative film not environmentally, the utility model provides a kind of for packing the degradable fresh-keeping of fruits and vegetables
Film.
The utility model solves the technical scheme that is used of above-mentioned technical problem：
A kind of degradable preservative film for being used to pack fruits and vegetables, it is characterised in that the preservative film includes basalis, intermediate layer
And upper strata, the basalis is the internal layer that is directly contacted with fruits and vegetables, the upper strata be after preservative film parcel fruits and vegetables with outside air
The outer layer of contact, is connected between the basalis and intermediate layer by the first adhesive layer, is passed through between the intermediate layer and upper strata
Second adhesive layer is connected, and the basalis is polyethylene layer, and the intermediate layer is nylon layer, and the upper strata is polyvinyl chloride layer,
First adhesive layer uses PA glue, and second adhesive layer uses PE glue.
It is preferred that the thickness of the polyethylene layer is 0.1~0.2um.
It is preferred that the thickness of the nylon layer is 0.1~0.2um.
It is preferred that the thickness of the polyvinyl dichloride layer is 0.1~0.2um.
It is preferred that the polyethylene layer uses low density polyvinyl-chloride.
It is preferred that polyvinyl dichloride of the polyvinyl dichloride layer using doping starch.
The utility model has the advantage of：The utility model provides a kind of degradable preservative film for being used to pack fruits and vegetables, should
The basalis of preservative film is using the polyethylene for being adapted to food contact, and the harmfulness to food is small, and ensures the security of food, together
When polyvinyl dichloride layer using doped with starch polyvinyl dichloride so that preservative film is after utilize, it is possible to achieve it is fresh-keeping use
It is complete, the degradation to preservative film is realized by the microorganism in soil.
