The utility model has the advantages of: can prevent infiltration gaseous and steam, prevent liquid, fragrant smell, gas, reach seeing through of light to have superior heat sealability and good transparency.
Description
Technical field
The utility model relates to a kind of multi-layer co-extruded film, belongs to packaging material field, is mainly used in the fresh-keeping packaging of food.
Background technology
The application of multi-layer co-extruded film, is formed by the Material cladding of different performance, makes plastic products have the good characteristic of different materials concurrently, characteristically carry out complementation, thus make plastic products obtain required performance and outward appearance: as oxygen, damp proof barrier, resistance permeability, the transparency, fragrance protectiveness, heat insulating ability, antiultraviolet, resistance tocrocking, thermophilic digestion, low temperature heat seal, and the mechanical performance such as intensity, rigidity, hardness, puncture resistance, resistance to tearing and printing etc.Change the limitation that homogenous material plastic products have, greatly improve the combination property of plastic products.
At present, due to the restriction of production equipment, the limit of most of coextrusion-lamination film is seven layers or nine layers, as China Patent No. ZL201120118910.1, disclose a kind of air-cushion film, it is characterized in that: described air-cushion film is seven-layer co-extrusion film, and it is followed successively by from top to bottom: the first metallocene polyethylene layer, the second metallocene polyethylene layer, the first adhesive layer, nylon layer, the second adhesive layer, the 3rd metallocene polyethylene layer and the 4th metallocene polyethylene layer.The utility model air-cushion film, intensity is high, good toughness, heat sealability are good.
And for example China Patent No. ZL201120118884.2, disclose a kind of air-cushion film for container, it is characterized in that: the described air-cushion film for container is seven-layer co-extrusion film, and it is followed successively by from top to bottom: metallocene polyethylene layer, the first adhesive layer, nylon layer, the second adhesive layer, low density polyethylene layer, the first linear low density polyethylene layer and the second linear low density polyethylene layer.The utility model is used for the air-cushion film of container, and puncture resistance is high, good toughness, heat sealability are good, cost is low.
But the up-to-date production equipment in the world successfully uses the tape casting to produce eleventh floor composite membrane.Eleventh floor composite membrane all has great development space in food and drink and medicine instrument industry, as extended meat, dairy produce, the fresh food normal temperature pot-life under preservative free condition, extend the shelf life and shelf life, fresh-keeping, guarantor's taste, makes food reach nuisanceless free of contamination object etc.; Or for the preservation of medicine, need the infiltration stoping gas and steam, stop liquid, fragrance, gas and light through, and there is superior heat sealability and excellent transparency.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of multi-layer co-extruded film, can stop the infiltration of gas and steam, stop liquid, fragrance, gas and light through, and there is superior heat sealability and excellent transparency.
The utility model solves the problems of the technologies described above taked technical scheme: a kind of multi-layer co-extruded film, wherein, a LLDPE layer, the 2nd LLDPE layer, an EVA layer, the first viscose glue oxidant layer, a PA layer, evoh layer, the 2nd PA layer, the second viscose glue oxidant layer, the 2nd EVA layer, the 3rd LLDPE layer and the 4th LLDPE layer is followed successively by from outside to inside.
On the basis of such scheme, a described LLDPE layer raw material is 80%LLDPE and 20%mPE, accounting for integral thickness ratio is 13%, 2nd LLDPE layer raw material is 80%LLDPE and 20%mPE, accounting for integral thickness ratio is 20%, one EVA layer raw material is 80%EVA and 20%LDPE, accounting for integral thickness ratio is 5%, it is 5% that first viscose glue oxidant layer accounts for integral thickness ratio, it is 5% that one PA layer accounts for integral thickness ratio, it is 4% that evoh layer accounts for integral thickness ratio, it is 5% that 2nd PA layer accounts for integral thickness ratio, it is 5% that second viscose glue oxidant layer accounts for integral thickness ratio, 2nd EVA layer raw material is 80%EVA and 20%LDPE, accounting for integral thickness ratio is 5%, 3rd LLDPE layer raw material is 80%LLDPE and 20%mPE, accounting for integral thickness ratio is 20%, 4th LLDPE layer raw material is 80%LLDPE and 20%mPE, accounting for integral thickness ratio is 13%.
The utility model has the advantage of: the infiltration that can stop gas and steam, stop liquid, fragrance, gas and light through, and there is superior heat sealability and excellent transparency.
