Description
Technical field
The utility model belongs to acceptable packaging material technical field, particularly a kind of polyvinyl chloride cold stamping solid medicinal composite hard sheet.
Background technology
PVC plastic uptake and medical aluminum foil PTP is adopted to carry out heat seal packaging in existing Key works Drug packing industry, there is performance deficiency such as obstruct water vapour, oxygen etc. in PVC, the resting periods such as medicine, health products, food are short, and the light transmission of PVC effectively can not intercept ultraviolet, and easily aging under Ultraviolet radiation, produce toxic gas.Simultaneously, the adhesive first adopted is toluene or the ethyl acetate solvent borne polyurethane hot setting adhesive of non-Environmental Safety, just this kind of non-Environmental Safety adhesive is employed like this when producing PET/AL/PE drug and food composite hard sheet, cause the pollution of poisonous toluene or the discharge of ethyl acetate solvent gas and inflammable and explosive potential safety hazard to production environment, also make the sanitary toxicology of composite hard sheet product itself be affected.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the polyvinyl chloride cold stamping solid medicinal composite hard sheet of a kind of long service life, safety and sanitation.
The purpose of this utility model realizes by following technical proposal: a kind of polyvinyl chloride cold stamping solid medicinal composite hard sheet, comprise the aramid layer set gradually, aluminium foil layer, polyvinyl chloride layer, it is characterized in that, aluminium foil layer surface be coated with urethane resin layer and described urethane resin layer between aluminium foil layer and aramid layer, described aramid layer and urethane resin layer, the adhesive layer adopting the polyurethane-modified polyacrylate of alcohol-water to make is equipped with between aluminium foil layer and urethane resin layer, polyvinyl chloride layer is coated with heat-sealing glue-line, plinthitic horizon is had at heat-sealing glue-line outer application, aramid layer is coated with radiation false proof layer, radiation false proof layer is coated with preservative film layer, printed layers is had in preservative film layer arranged outside, cellophane layer is provided with outside printed layers.
Compared with prior art, the utility model has the following advantages:
1, inter-layer bonding force increases, and steam, OTR oxygen transmission rate reduce, and barrier property increases, and global formation performance improves; Can stable prod quality, extend product service life and improving product security performance.
2, adopt and there is the stronger polyurethane-modified acrylate resin of boiling resistance alcohol-water, replace original non-Environmental Safety toluene or ethyl acetate solvent borne polyurethane hot setting adhesive, bonding modification is carried out to polyester/aluminium/polyvinyl medicine composite hard sheet, during laminating production what dry discharge is nontoxic nonflammable alcohol-water mixing gas, not only thoroughly overcome the shortcoming of existing non-environment-friendly adhesive, maintain again the good comprehensive serviceability of this composite hard sheet simultaneously, thus improve the production technology quality grade of this composite hard sheet product well, achieve good environment protection modification effect.
3, be coated with heat-sealing glue-line in lower polyethylene based film, have plinthitic horizon at heat-sealing glue-line outer application, because heat-sealing film surface is burnishing surface, when boning with bubble-cap, adhesion strength is little, passes through plinthitic horizon, can adhesion strength be strengthened, heat-sealing glue-line can be firmly bonded on bubble-cap by bubble-cap.
4, by preservative film layer, making this composite hard sheet nonpoisonous and tasteless, harmless when packing medicine, there is good humidity resistance, ensure that the quality guarantee period of medicine, having possessed the advantage of safe ready and long shelf-life.
5, cellophane layer is had in printed layers arranged outside, printed layers can be completely cut off by cellophane layer to contact with the direct of tablet, avoid the ink when placing tablet in printed layers directly to contact with tablet the situation causing tablet to pollute, and cellophane layer conveniently can be torn easily when disassembling packaging.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, plinthitic horizon; 2, glue-line is sealed; 3, polyvinyl chloride layer; 4, aluminium foil layer; 5, adhesive layer; 6, urethane resin layer; 7, aramid layer; 8, radiation false proof layer; 9, preservative film layer; 10, printed layers; 11, cellophane layer.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this polyvinyl chloride cold stamping solid medicinal composite hard sheet comprises the aramid layer 7 set gradually, aluminium foil layer 4, polyvinyl chloride layer 3, be coated with urethane resin layer 6 on aluminium foil layer 4 surface and described urethane resin layer 6 between aluminium foil layer 4 and aramid layer 7, described aramid layer 7 and urethane resin layer 6, the adhesive layer 5 adopting the polyurethane-modified polyacrylate of alcohol-water to make is equipped with between aluminium foil layer 4 and urethane resin layer 6, polyvinyl chloride layer 3 is coated with heat-sealing glue-line 2, plinthitic horizon 1 is had at heat-sealing glue-line 2 outer application, aramid layer 7 is coated with radiation false proof layer 8, radiation false proof layer 8 is coated with preservative film layer 9, printed layers 10 is had in preservative film layer 9 arranged outside, cellophane layer 11 is provided with outside printed layers 10.
Inter-layer bonding force increases, and steam, OTR oxygen transmission rate reduce, and barrier property increases, and global formation performance improves; Can stable prod quality, extend product service life and improving product security performance.
Adopt and there is the stronger polyurethane-modified acrylate resin of boiling resistance alcohol-water, replace original non-Environmental Safety toluene or ethyl acetate solvent borne polyurethane hot setting adhesive, bonding modification is carried out to polyester/aluminium/polyvinyl medicine composite hard sheet, during laminating production what dry discharge is nontoxic nonflammable alcohol-water mixing gas, not only thoroughly overcome the shortcoming of existing non-environment-friendly adhesive, maintain again the good comprehensive serviceability of this composite hard sheet simultaneously, thus improve the production technology quality grade of this composite hard sheet product well, achieve good environment protection modification effect.
Be coated with heat-sealing glue-line 2 in lower polyethylene based film, have plinthitic horizon 1 at heat-sealing glue-line 2 outer application, because heat-sealing glue-line 2 surface is burnishing surface, when boning with bubble-cap, adhesion strength is little, by plinthitic horizon 1, can adhesion strength be strengthened, heat-sealing glue-line 2 can be firmly bonded on bubble-cap by bubble-cap.
By preservative film layer 9, making this composite hard sheet nonpoisonous and tasteless, harmless when packing medicine, there is good humidity resistance, ensure that the quality guarantee period of medicine, having possessed the advantage of safe ready and long shelf-life.
Cellophane layer 11 is had in printed layers 10 arranged outside, printed layers 10 can be completely cut off by cellophane layer 11 to contact with the direct of tablet, avoid the ink when placing tablet in printed layers 10 directly to contact with tablet the situation causing tablet to pollute, and cellophane layer 11 conveniently can be torn easily when disassembling packaging.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
