Description

Food package film
Technical field
The present invention relates to a kind of food package film.
Background technology
Composite soft packaging industry starts to grow up in 20 middle of century, and gradually shows it in packaging for foodstuff The importance of aspect, this kind of composite membrane are made up of base material, adhesive, barrier material, heat-sealable material, printing layer and protective layer etc..
Food packaging items species is various, and requirement of the different contents to packaging material is different, there is the food of many Product require shading, block water, hinder oxygen, particularly some food packaging requirement easily openables.In the market there is an urgent need to a kind of composite, Good barrier, heat sealability etc. can be kept, the easy-to-rupture that there are other composites not possess again.
The content of the invention
The technical problem to be solved in the present invention is：Based on above mentioned problem, there is provided a kind of food package film.
The technical solution adopted for the present invention to solve the technical problems is：A kind of food package film, is answered using three-decker Conjunction forms, and is followed successively by biaxially oriented polypropylene film layer, aluminum polyester film layer and polyethylene film layer, biaxial stretching polypropylene from top to bottom Between alkene film layer and aluminum polyester film layer, adhesive is coated between aluminum polyester film layer and polyethylene film layer.
Further, adhesive is polyurethane binder.
The beneficial effects of the invention are as follows：The food package film of the present invention is combined by multilayer material, has high-barrier Property, good easy-to-rupture, pliability is moderate, is used conveniently and safely.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Wherein：1. biaxially oriented polypropylene film layer, 2. aluminum polyester film layers, 3. polyethylene film layers.
Embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram only with signal side Formula illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of food package film as shown in Figure 1, is combined using three-decker, is followed successively by biaxial tension from top to bottom Polypropylene film 1, aluminum polyester film layer 2 and polyethylene film layer 3, biaxially oriented polypropylene film layer 1 and aluminum polyester film layer 2 it Between, between aluminum polyester film layer 2 and polyethylene film layer 3 be coated with adhesive, adhesive is polyurethane binder.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
