Abstract
The utility model relates to a barrier membrane of water vapour and oxygen, and the barrier membrane of the water vapour and the oxygen comprises a resin film layer (4) a silica coating (3), an adhesive layer (2) and a casting polypropylene film layer (1). Permeability of the water vapour and the oxygen can be reduced by designing the barrier membrane to be a multi-layer composite structure and plating the silica layer on the surface of a resin film in an evaporation mode. The barrier membrane of the water vapour and oxygen is further provided with the casting polypropylene film layer due to the fact that heat sealability of the casting polypropylene film layer is good, a follow-up process such as bag making in a heat-seal molding mode can be conducted conveniently. Further, due to the fact that the structure of the barrier membrane is simple in structure, processing and production can be achieved by using an ordinary plastic composite machine, and therefore, low production cost can be achieved.
Description
[technical field]
The utility model relates to layer barrier film constructions, more particularly, relates to a kind of steam oxygen blocking barrier film.
[background technology]
At packaging field, often relate to the protection problem of packing content, never degenerate or prevent product corruption, suction, oxidation etc. for guaranteeing content, need packaging structure can play extraordinary iris action.In packaging for foodstuff or medical packaging industry, the application that need to use Obstruct membrane is just more.
The group barrier film that two kinds of obstruct mode are arranged at present on the market, a kind of is Obstruct membrane by the stacked composition of multilayer film, another kind is by barrier material is mixed the Obstruct membrane of again blow molding with the raw material of plastics.The former has better gas barrier property, but low-molecular-weight little molecule still has part to see through, and the mixed film gap is large, and the gap is passed through by gas easily.Therefore resistance oxygen, the steam that how to improve packing is the problem that needs at present solution.
[utility model content]
The technical problems to be solved in the utility model is, problem for the poor performance that has blocking oxygen, obstruct steam in the packing film of the prior art, a kind of novel steam oxygen blocking barrier film is provided, can obtains the performance of better blocking oxygen and obstruct steam.
The technical scheme that its technical matters that solves the utility model adopts is: construct a kind of steam oxygen blocking barrier film, comprise the resin film layer, silica dioxide coating, adhesion agent layer and the casting polypropylene film layer that are arranged in order.
In steam oxygen blocking barrier film described in the utility model, the thin layer that poly terephthalic acid class plastics are made.
In steam oxygen blocking barrier film described in the utility model, described adhesion agent layer is that glue, factice or hot melt adhesive evenly are coated in the thin layer that the silica dioxide coating surface forms.
In steam oxygen blocking barrier film described in the utility model, the both sides of described resin film layer are equipped with silica dioxide coating.
Implement steam oxygen blocking barrier film described in the utility model, has following beneficial effect: be set to multi-layer compound structure by Obstruct membrane, and at surface resin film steam coating silicon dioxide layer, can reduce the steam oxygen permeability, and this steam oxygen blocking barrier film has the cast polypropylene film layer, because the heat sealability that the cast polypropylene film layer has is good, can conveniently seal the subsequent techniques such as moulding bag.In addition, because whole obstruct rete is simple in structure, use the common plastic compounding machine just can processing and fabricating, productive costs be lower.
The utility model is described in further detail below in conjunction with drawings and Examples.
[description of drawings]
Fig. 1 is the structural representation of steam oxygen blocking barrier film preferred embodiment described in the utility model;
Fig. 2 is the structural representation of another embodiment of steam oxygen blocking barrier film described in the utility model.
[specific embodiment]
As shown in Figure 1, in the preferred embodiment of steam oxygen blocking barrier film described in the utility model, comprise the resin film layer 4, silica dioxide coating 3, adhesion agent layer 2 and the casting polypropylene film layer 1 that are arranged in order.Wherein, resin film layer is preferably the thin layer that poly terephthalic acid class plastics are made, and adhesion agent layer is that glue, factice or hot melt adhesive evenly are coated in the thin layer that the silica dioxide coating surface forms.Wherein silica dioxide coating is by the surface of evaporation process processing at resin film layer 4.Be set to multi-layer compound structure by Obstruct membrane, and at surface resin film steam coating silicon dioxide layer, can reduce the steam oxygen permeability; And this steam oxygen blocking barrier film has the cast polypropylene film layer, because the heat sealability that the cast polypropylene film layer has is good, can conveniently seal the subsequent techniques such as moulding bag.In addition, because whole obstruct rete is simple in structure, use the common plastic compounding machine just can processing and fabricating, productive costs be lower.
Because in the evaporation process process, a side that only limit at resin film layer 4 arranges silica dioxide coating, processes more complicated; For easy to process, as shown in Figure 2, in another embodiment of the described steam oxygen blocking of utility model barrier film, preferably in the both sides of resin film layer 4 silica dioxide coating is set all, namely steam oxygen blocking barrier film comprises silica dioxide coating, resin film layer, silica dioxide coating, adhesion agent layer and casting polypropylene film layer successively.
In manufacturing process, the mode by evaporation processes silica dioxide coating 3 in resin film layer 4 one sides first, and guarantees that as far as possible silica dioxide coating is not impaired in the course of processing, as not producing the defectives such as fold.Be coated with adhesion agent layer at silica dioxide coating 3 again, adhesion agent layer can adopt dry type compound or be coated with compound mode and make; Be compounded on the adhesion agent layer casting polypropylene film layer is smooth again, finish manufacturing of steam oxygen blocking barrier film.Owing to select different solid types and the condition of following to make Bonding strength produce difference, when being fitted in casting polypropylene film layer 1 on the adhesion agent layer, carbonic acid gas etc. is difficult to remove when the entraps globule of solid, the bubble of sneaking into or solid generation maturation, and it is residual that adhesion agent layer 2 can produce bubbles; For this reason, be preferably on the silica dioxide coating 3 the coating adhesion agent layer after, after 1 to 3 day, compound casting polypropylene film layer can prevent residual bubble in the adhesion agent layer so again in maturation under 40 ° of C conditions.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
