Description
Technical field
the utility model relates to a kind of novel co-extrusion packaging film.
Background technology
novel co-extrusion packaging film of the prior art, usually needs the ability can with excellent blocking oxygen, steam, smell, prevents the change of food, medicine, chemicals.If patent publication No. is the patent document of CN103522694A; disclose a kind of High-barrier multilayer co-extrusion plastic film; comprise: outer sealing, barrier layer, TPU film layer, protective layer and tack coat; described outer sealing, TPU film layer are set gradually from top to bottom with barrier layer and are connected by tack coat between any two; described protective layer is separately positioned on outer sealing and barrier layer, and is connected by tack coat.
Utility model content
the technical problems to be solved in the utility model is to provide a kind of novel co-extrusion packaging film.
in order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of novel co-extrusion packaging film, comprise packaging top layer, pack internal layer, be set in turn in five layers of sandwich layer between described packaging top layer to described packaging internal layer, the material on described packaging top layer is polyamide, polyolefin or polyester, the material of described internal layer is polyethylene, the material that ground floor sandwich layer, second layer sandwich layer use is polyamide, the material that third layer sandwich layer uses is ethylene-vinyl alcohol copolymer, and the material that the 4th layer of sandwich layer, layer 5 sandwich layer use is polyethylene.
in some embodiments, between described packaging top layer and ground floor sandwich layer, between ground floor sandwich layer and second layer sandwich layer, the 4th layer bond respectively by bonding resin layer between sandwich layer and layer 5 sandwich layer and between layer 5 sandwich layer and described packaging internal layer.
in some embodiments, the thickness of described packaging top layer, described packaging internal layer and the sandwich layer described in five layers is respectively 0.05mm ~ 0.1mm.
scope of the present utility model, is not limited to the technical scheme of the particular combination of above-mentioned technical characteristic, also should contain simultaneously and be undertaken being combined by above-mentioned technical characteristic or its equivalent feature and other technical scheme of being formed.The technical characteristic that such as, disclosed in above-mentioned feature and the application (but being not limited to) has similar functions is replaced mutually and the technical scheme etc. formed.
because technique scheme is used, the utility model compared with prior art has following advantages: the utility model provides a kind of co-extrusion packaging film of new technical scheme, for packing the product such as food, medicine, there is excellent blocking oxygen, steam etc. enter, also can prevent the volatilization of food flavor simultaneously, ensure food original flavor, there is good heat sealability, meet the requirement of sterilization, avoid microorganism to exist and destroy food, to food, medicine etc., there is higher barrier protection.
Accompanying drawing explanation
accompanying drawing 1 is structural representation of the present utility model;
wherein: 1, pack top layer; 2, ground floor sandwich layer; 3, second layer sandwich layer; 4, third layer sandwich layer; 5, the 4th layer of sandwich layer; 6, layer 5 sandwich layer; 7, internal layer is packed; 8, bonding resin layer.
Detailed description of the invention
as shown in Figure 1, a kind of novel co-extrusion packaging film, comprise packaging top layer 1, packaging internal layer 7, be set in turn in five layers of sandwich layer between packaging top layer 1 to packaging internal layer 7, five layers of sandwich layer from down to lower be ground floor sandwich layer 2, second layer sandwich layer 3, third layer sandwich layer 4, the 4th layer of sandwich layer 5 and layer 5 sandwich layer 6 respectively.
the material on packaging top layer 1 is polyamide PA, polyolefin PO or polyester PET, and because oxygen can cause the oxidation deterioration of fat and protein, so adopt the material with excellent blocking oxygen ability, what adopt in the present embodiment is polyester PET.The material of internal layer is polythene PE, and the material that ground floor sandwich layer 2, second layer sandwich layer 3 use is polyamide PA, and the material that third layer sandwich layer 4 uses is ethylene-vinyl alcohol copolymer EVOH, and the material that the 4th layer of sandwich layer 5, layer 5 sandwich layer 6 use is polythene PE.
packaging top layer 1 and ground floor sandwich layer 2 between, between ground floor sandwich layer 2 and second layer sandwich layer 3, the 4th layer between sandwich layer 5 and layer 5 sandwich layer 6 and layer 5 sandwich layer 6 and packaging internal layer 7 between bond respectively by bonding resin layer 8.Material due to third layer sandwich layer 4 is ethylene-vinyl alcohol copolymer EVOH, and ethylene-vinyl alcohol copolymer EVOH itself has bond properties, thus directly can be bonded together with second layer sandwich layer 3 and the 4th layer of sandwich layer 5.Binder resin can adopt conventional packaging film viscose glue, as TIE etc.
polyamide PA, ethylene-vinyl alcohol copolymer EVOH, polyester PET have higher oxygen resistance, polythene PE has that higher resistance is moist, lower temperature resistance, and polyamide PA, polyester PET also have higher oil resistance, mechanicalness, high temperature resistant sterilizing performance low temperature resistant again, thus the utility model can have higher barrier protection to food, medicine etc., extends the pot-life.
packaging top layer 1, packaging internal layer 7 and the thickness of five layers of sandwich layer are respectively 0.05mm ~ 0.1mm.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
