Description
Technical field
This utility model relates to pharmaceutical packaging structure field, particularly to one fixed point coating aluminum foil-plastic-aluminum foil.
Background technology
Aluminum foil-plastic-aluminum foil paper tinsel is a kind of thermoforming plastic bubble-cap and the combination of cold forming clad aluminum, and blister package keeps bubble
Molded dimension is constant, and the area around bubble-cap is the most wider so that the hot belt type bubble-cap composite membrane after cold forming can steep with thermoforming
In cover sealing, compensate for the aluminum-plastic packaged middle printing opacity of tradition, the problem of water preventing ability difference, now the most progressively accepted by domestic manufacturer.
The composition of aluminum foil-plastic-aluminum foil (also referred to as aluminum-plastic-aluminum) is polyamide or polyester/aluminium/binding agent, and it is in certain temperature
A kind of sheet material by special equipment, this different materials being composited under degree and pressure, is specifically for strengthening tradition plastic-aluminum bag
The barrier of dress and a kind of packaged form of growing up, only need to add an aluminum in polrvinyl chloride (PVC) bubble-cap stiff sheet the most again
The lid moulding composite membrane is the formation of aluminum foil-plastic-aluminum foil packaging.
In the prior art, the usual structure of torrid zone bubble-cap aluminum is polyamide PA25/ aluminium foil AL60/ acrylic acid VC glue, its
Middle VC glue uses the full version coating method of aluminium foil surface, but actually VC glue simply plays heat sealing effect in heat-seal land, at other
The VC glue of position coating is not all used effectively.The working concentration of solvent-borne type heat-seal coating is usually 25%, and butt coating weight is
3.0g/m2, being computed often being coated with one square metre, then the organic solvent amount discharged in air is 2.25g.These are discharged into greatly
Organic solvent (being called for short VOCs) in gas, on the one hand can cause serious atmosphere light chemical combination to pollute, cause greenhouse effect, cause pole
Big environmental hazard, makes crop production reduction, is entered in human body by breathing, and liver and nervous system to human body cause damage,
Harm enterprise direct labor and the health of surrounding population；On the other hand the significant wastage of VOC raw material is caused.
Using fixed point applying structure, be the most only just coated with VC glue at the position needing heat-sealing, remaining position is not coated with VC glue, this
Within the coating weight of VC glue just can be reduced to original 40% by sample, i.e. realize the gluing cost savings of more than 60%, simultaneously
VOCs discharge capacity decreases 60%, thus feature of environmental protection torrid zone aluminum produce in is greatly improved.
Utility model content
The deficiency existed for prior art, this case is by the improvement to existing product structure, it is provided that a kind of fixed point is coated with
Cloth aluminum foil-plastic-aluminum foil.
For achieving the above object, this case is achieved through the following technical solutions:
A kind of fixed point coating aluminum foil-plastic-aluminum foil, it includes: aluminium foil layer, this aluminium foil layer have relative first surface and
Second surface, described first surface is provided with adhesive for polyurethane layer, and this adhesive for polyurethane layer surface is provided with aramid layer or poly-
Ester layer；The edge of described second surface is provided with the VC adhesive tape of fixed point coating；Wherein, at described adhesive for polyurethane layer with described
Ink printing block it is additionally provided with between aramid layer or polyester layer.
Preferably, described fixed point coating aluminum foil-plastic-aluminum foil, wherein, the thickness of described aramid layer or polyester layer is
15-40μm。
Preferably, described fixed point coating aluminum foil-plastic-aluminum foil, wherein, the thickness of described aluminium foil layer is 30-100 μm.
Preferably, described fixed point coating aluminum foil-plastic-aluminum foil, wherein, the thickness of described VC adhesive tape is 4-8 μm, width
For 8-12mm.
Preferably, described fixed point coating aluminum foil-plastic-aluminum foil, wherein, described VC adhesive tape is acrylic resin.
Preferably, described fixed point coating aluminum foil-plastic-aluminum foil, wherein, described VC adhesive tape is vinyl chloride-vinyl acetate resin.
Preferably, described fixed point coating aluminum foil-plastic-aluminum foil, wherein, described VC adhesive tape is polyester resin.
Preferably, described fixed point coating aluminum foil-plastic-aluminum foil, wherein, with described in the second surface of described aluminium foil layer
The part that VC adhesive tape contacts is arranged to frosting.
Preferably, described fixed point coating aluminum foil-plastic-aluminum foil, wherein, at described aramid layer or polyester layer near institute
The side surface stating ink printing block is provided with honeycomb groove.
The beneficial effects of the utility model are: this case, by the improvement to existing product structure, is the most only needing heat-sealing
Position is just coated with VC glue, and remaining position is not coated with VC glue, within thus the coating weight of VC glue being reduced to original 40%,
I.e. realizing the gluing cost savings of more than 60%, VOCs discharge capacity decreases 60% simultaneously, while energy consumption reduces and significantly
Improve the feature of environmental protection during torrid zone aluminum produces, play the effect of energy-saving and emission-reduction, simple in construction, implementation cost that this case uses be low,
Preservation and effect is good.
