Abstract
The utility model discloses a high resistant separates paper and moulds complex film, including the cow hide ply, separation nature adhesive phase and polyolefin rete, include the cow hide ply in proper order by from the top down, separation nature adhesive phase, the polyolefin rete is constituteed, and the kraft paper that this kind of high resistant was moulded at a distance from paper has excellent intensity, deflection and marresistance, separation nature tie coat has high barrier properties and low price, the polyolefin rete has high block -water performance and has fine heat sealability complex film to have high block -water performance and have fine heat sealability, making paper mould the complex film like this, not only to have an outward appearance height well -pressed, intensity and resistant scotch, and the shelf life of content extension, and is suitable for being generalized to use.
Description
Technical field
This utility model relates to a kind of composite membrane, specifically a kind of high-barrier paper-plastic composite film, belongs to Food Packaging technology field.
Background technology
At present, packaging material used in food packaging industry need to possess in following characteristic whole or a kind of, just can have the market competitiveness: (1) protection food is difficult to impaired；(2) food is had the longer shelf-life；(3) packing cost is cheap.There is the packaging material for food of characteristic (1), need the physical and mechanical properties with higher-strength, in the market product have the composite membrane of the plastic sheeting containing aluminium foil, but its price comparison is expensive；There is the packaging material for food of characteristic (2), need that there is high-barrier oxygen and the high obstructing performance of obstruct aqueous vapor, existing market is conventional to have polyvinyl alcohol (PVA) film, nylon (BOPA) film, polythene-ethenol (EVOH) film, polyester (PET) film, the composite membrane of plastic sheeting containing aluminium foil or aluminized, polyvinylidene chloride (PVDC) film, but great majority are all to be utilized with the form of composite membrane.But these films are often restricted because of the highest also utilization in some field of expensive or intensity.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of high-barrier paper-plastic composite film, utilize the adhesive glue (such as modified polyvinylalcohol) of high barrier by paper-plastic stick together, the dry solidification of adhesive glue is ensured, it is provided that there is the scratch resistance high barrier paper-plastic package film of higher intensity, high obstructing performance and lower cost by the infiltration characteristic of paper.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high-barrier paper-plastic composite film, including layers of kraft paper, barrier adhesive phase and polyolefin film layer, include that layers of kraft paper, barrier adhesive phase, polyolefin film layer form the most successively.
Further, described barrier adhesive phase is modified polyvinylalcohol (PVA) adhesive layer.
Further, described layers of kraft paper is bondd with polyolefin film layer by barrier adhesive phase.
Further, described layers of kraft paper is 50～300g/m2, barrier adhesive phase butt coating weight is 2～20g/m2, polyolefin film layer thickness is 10～200 μm.
The beneficial effects of the utility model are: the barrier adhesive phase of this kind of high-barrier paper-plastic composite film is modified polyvinylalcohol (PVA) adhesive layer, and the compactness that improve connection adds again the safety of use；Described kraft paper is bondd with polyolefin film layer by barrier adhesive phase, improve the sealing of connection, and the kraft paper of this kind of high-barrier paper has intensity, deflection and the marresistance of excellence, barrier tack coat has high obstructing performance and cheap, polyolefin film layer has high water resistant performance and has good heat sealability composite membrane have high water resistant performance and have good heat sealability, outward appearance height is well-pressed, intensity and scratch resistance so to make paper-plastic composite film not only have, and the extended shelf-life of content, it is suitable for promoting the use of.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram；
In figure: 1-layers of kraft paper, 2-barrier adhesive phase, 3-polyolefin film layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.Obviously, described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1: a kind of high-barrier paper-plastic composite film, including layers of kraft paper 1, barrier adhesive phase 2 and polyolefin film layer 3, include that layers of kraft paper 1, barrier adhesive phase 2, polyolefin film layer 3 form the most successively.
As optimisation technique scheme of the present utility model: described barrier adhesive phase 2 is modified polyvinylalcohol (PVA) adhesive layer；Described layers of kraft paper 1 is bondd with polyolefin film layer 3 by barrier adhesive phase 2；Described layers of kraft paper 1 is 50～300g/m2, barrier adhesive phase butt coating weight is 2～20g/m2, polyolefin film layer 3 thickness is 10～200 μm.
As using method of the present utility model: this kind of high-barrier paper-plastic composite film normally uses after checking the sealing of connection and tightness in use, not only reduce the cost of production and the feature of environmental protection is good, decrease pollution, improve applicable scope.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
The above; it is only preferred embodiment of the present utility model; not in order to limit this utility model, every any trickle amendment, equivalent and improvement made above example according to technical spirit of the present utility model, within should be included in the protection domain of technical solutions of the utility model.
