The aluminum-plastic packaged PE composite hard sheet of usingTechnical field
The utility model relates to a kind of composite hard sheet, especially relates to a kind of aluminum-plastic packaged PE of using composite hard sheet.
Background technology
Plastic-aluminum (PTP) packing that solid medicine, food extensively adopt at present, PTP is the abbreviation of Press Through Packaging, literal translation is " by pressure, packing ", in industry, more regular appellation is medicine Packaging Aluminum Foil, also be blister package aluminium foil, generally by polyvinyl chloride (PVC) hard sheet and two kinds of packaging material of PTP aluminium foil, formed.
In existing PTP packing, tablet, capsule-type food is contact PVC layer and adhesive layer directly, and in frothing moulding, filling, sealer process, PVC is repeatedly subject to the high temperature of nearly 200 ℃, but PVC layer, adhesive layer and medicine, Food Contact security allow people worry, because PVC is actually polyvinyl chloride, polyvinyl chloride is the polymer of vinyl chloride, in this polymer, generally contain a certain amount of VCM, VCM heat or oil will migrate on packed article, and VCM is a kind of noxious material, hinder health of human body.
Utility model content
The deficiency existing in order to overcome prior art, the utility model provides a kind of aluminum-plastic packaged PE of using composite hard sheet.
A kind of aluminum-plastic packaged PE composite hard sheet of using, comprise hard sheet layer, described composite hard sheet also comprises a PE rete and PTP aluminium foil layer, bonding by the first adhesive layer between described hard sheet layer and a PE rete, between a PE rete and PTP aluminium foil layer, by Heat Sealing, is integral.
Preferably, described PTP aluminium foil layer comprises the 2nd PE rete and medicinal aluminum foil layer, and described the 2nd PE rete extrudes rear by extrusion cladding machine and medicinal aluminum foil layer one side is compound.
Preferably, described medicinal aluminum foil layer opposite side is provided with printed layers, is coated with OP protective layer in printed layers.
Preferably, between described hard sheet layer and a PE rete, be provided with barrier layer, bonding by the second adhesive layer between described hard sheet layer and barrier layer, bonding by the 3rd adhesive layer between barrier layer and a PE rete.
Hard sheet of the present utility model can adopt PVC, PET, PP etc.; It,, as the framework material of PTP packing, can heat blow molding, has certain rigidity and barrier.
The utility model take hard sheet after base material coating binder with PE film carry out compound, after preheating on Aluminium-coating Packer, moulding, filling medicine or food with safe environment protection type PTP aluminium foil heat-sealing, finally by completing medicine packing after die-cut.
The contact-making surface of the utility model and medicine, food is transformed into PE by PVC, built-in medicine, food only contact PE layer, and PE is safe, the most stable internationally recognized packaging material, therefore can effectively solve PVC and the pollution problem of adhesive layer to medicine, food.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but protection domain of the present utility model is not limited to this.
Embodiment 1
With reference to Fig. 1, a kind of aluminum-plastic packaged PE composite hard sheet of using, comprise PVChard sheet layer 1, aPE rete 3 and PTP aluminium foil layer, bonding by the firstadhesive layer 2 between described PVChard sheet layer 1 and aPE rete 3, between aPE rete 3 and PTP aluminium foil layer, by Heat Sealing, be integral.
Described PTP aluminium foil layer comprises the2nd PE rete 4 and medicinalaluminum foil layer 5, and described the2nd PE rete 4 extrudes rear by extrusion cladding machine and medicinalaluminum foil layer 5 one side are compound.
Described medicinalaluminum foil layer 5 opposite side are provided with printedlayers 6, are coated with OPprotective layer 7 in printedlayers 6.
Adopting PVC hard sheet is that after base material coating polyurethane adhesive, to carry out dry type compound with PE film, after preheating on Aluminium-coating Packer, moulding, filling medicine orfood 8, with the heat-sealing of safe environment protection type PTP aluminium foil, finally by completing medicine after die-cut, packs.
Embodiment 2
With reference to Fig. 2, a kind of aluminum-plastic packaged PE composite hard sheet of using, comprise PEThard sheet layer 1, aPE rete 3 and PTP aluminium foil layer, between described PEThard sheet layer 1 and aPE rete 3, be provided with barrier layer 9, bonding by the second adhesive layer 10 between described PEThard sheet layer 1 and barrier layer 9, bonding by 11 layers of the 3rd adhesive between barrier layer 9 and a PE rete 3.Between the onePE rete 3 and PTP aluminium foil layer, by Heat Sealing, be integral.
Described PTP aluminium foil layer comprises the2nd PE rete 4 and medicinalaluminum foil layer 5, and described the2nd PE rete 4 extrudes rear by extrusion cladding machine and medicinalaluminum foil layer 5 one side are compound.
Described medicinalaluminum foil layer 5 opposite side are provided with printedlayers 6, are coated with OPprotective layer 7 in printedlayers 6.
Adopting PET hard sheet is that after base material coating polyurethane adhesive, to carry out dry type compound with PE film, after preheating on Aluminium-coating Packer, moulding, filling medicine orfood 8, with the heat-sealing of safe environment protection type PTP aluminium foil, finally by completing medicine after die-cut, packs.
The utility model hard sheet, can select different thickness according to size and the shape of packing medicine, food, to guarantee that the bubble-cap after moulding has certain rigidity and barrier.
