Description
Technical field
The utility model relates to packaging field, is specifically related to a kind of high-barrier package sheet material with good print, is processed as Yogurt container, dentifrice tube, cosmetic QC etc. for thermal finalization.
Background technology
Packaging material are divided into a variety of, and wherein having a class is the packaging material with high light-proofness, high barrier, for needing the food of shading preservation or the preservation of article, as Yoghourt, toothpaste and cosmetics etc.
The structure of the packaging material of common high barrier that can shading is: A, polyolefin/binder resin/aluminium foil/binder resin/polyolefin, or B, the polyolefin/binder resin/material layer/binder resin/polyolefin of aluminizing, or C, polyolefin/adhesive layer/barrier material/adhesive layer/polyolefin.The advantage of structure A is that light-proofness is good, barrier property is excellent, and shortcoming is that obsolete material reclaims difficulty, and cost is high; The advantage of structure B is that light-proofness is better, barrier property is comparatively excellent, and cost decreases, but still exists obsolete material to reclaim difficult problem; The advantage of structure C is that environmental protection, material recovery are convenient, and shortcoming is in order to meet light-proofness, and skin depth is high, flexible poor, therefore surface is difficult to printing.Taking Yogurt container as example, mostly existing Yogurt container box body is to paste the wrapping paper with products propaganda information, but not directly prints on the packaging material of its box body; Therefore, this has just increased the manufacturing process of packing box.
Therefore manufacture the overall plastic high-barrier package sheet material that a kind of cost is low, have high light-proofness, high barrier, good print.
Summary of the invention

For achieving the above object, the high-barrier package sheet material with good print of the present utility model, comprise by outer and in the printing basement membrane, the first glue layer, photomask, the second glue layer, the coextrusion blow film that set gradually; Wherein, coextrusion blow film comprise as the barrier layer of coextrusion blow film sandwich layer, be positioned at coextrusion blow film one side surface for the gluing superficial layer of photomask, be positioned at the hot sealing layer for sealing on coextrusion blow film opposite side surface.
In high-barrier package sheet material of the present utility model, photomask, for improving the light-proofness of package sheet material, is avoided the active component of its packing material or easily illumination oxidation composition inactivation or inefficacy under illumination; Printing basement membrane is for print product trade mark and information introduction.Compare with existing Yoghourt, toothpaste and overall plastic high-barrier package sheet material used for cosmetic, high-barrier package sheet material of the present utility model is by arrange printing basement membrane and photomask simultaneously, the content of thickness, shading component that makes to improve photomask is to improve light-proofness but damage it flexible time, do not affect the printing easiness of package sheet material, and then can obtain the overall plastic high-barrier package sheet material that cost is low, have high light-proofness, high barrier, good print.
From gluing easiness, the photomask gluing easiness angle consideration of extrusion blow plastic film together of printing easiness, printing basement membrane and photomask, preferred technical scheme is that described printing basement membrane is selected from the one in biaxially oriented polypropylene film, biaxial stretching polyester film and biaxial tension nylon film; Described photomask is to be added with the female noncrystallineization polyester film of white.White is female, as titanium dioxide, calcium carbonate etc.
The light-proofness of taking into account the flexible and noncrystallineization polyester film of cost, printing basement membrane, preferably technical scheme is, and the thickness of described printing basement membrane is 10 ~ 40 μ m, and the thickness of described photomask is 150 ~ 250 μ m.
Select coextrusion blow film as the material that plays heat-sealing, iris action, this is can reduce film thickness because of coextrusion blow film, and its function particularly barrier property be better than traditional gluing compound composite membrane obtaining.In the structural design of coextrusion blow film, preferred technical scheme is, described coextrusion blow film comprise by outer and in the superficial layer, outer tack coat, barrier layer, interior tack coat, the hot sealing layer that set gradually.
Wherein, described barrier layer can be evoh layer; Described inside and outside tack coat can be ethylene-vinyl acetate layer; Described hot sealing layer and superficial layer can be polyethylene layer.
In order further to improve the heat sealability of material, ensure the anti-warpage properties of material simultaneously, preferred technical scheme is, described coextrusion blow film also comprises establishes subsurface layer and time hot sealing layer, subsurface layer is located between described superficial layer and described outer tack coat, and inferior hot sealing layer is located between described hot sealing layer and described interior tack coat; Subsurface layer and time hot sealing layer are polyethylene layer.
Consider from cost and performance perspective, preferred technical scheme is that the thickness of described coextrusion blow film is 150 ~ 250 μ m.
Consider from cost and performance perspective, preferred technical scheme is that the gross thickness of described high barrier sheet is 400 ~ 500 μ m.
Preferred technical scheme is that the surface of described printing basement membrane is also provided with printing ink layer.Printing ink layer, for the introduction of packaged product, also can reduce paper waste.
In order to increase printing fastness, avoid package sheet material ink in the process that is processed as corresponding box body, body to deform, preferred technical scheme is that described printing ink layer is located at the inner surface of described printing basement membrane.
Advantage of the present utility model and beneficial effect are: high-barrier package sheet material of the present utility model is by arrange printing basement membrane and photomask simultaneously, the content of thickness, shading component that makes to improve photomask is to improve light-proofness but damage it flexible time, do not affect the printing easiness of package sheet material, and then can obtain the overall plastic high-barrier package sheet material that cost is low, have high light-proofness, high barrier, good print.In addition, high-barrier package sheet material of the present utility model printing firmly, can reduce the advantages such as paper waste.
