Summary of the invention
The objective of the invention is at the high weak point of prior art cost and have only that the nylon adhesive aluminium foil just can finish and solve that the hard sheet of packaging aluminium strikes out that various concavities bubbles at the moment easily break, the technology prejudice of layering, wrinkling and delamination, provide a kind of can making to mould the aluminium membrane material and enter gold and mould state, coordinated constitutes the MULTILAYER COMPOSITE hermetically-sealed construction, more strong withstand voltage, have more leak tightness, high sealing cold pressing type packaging aluminium with low cost.
The object of the present invention is achieved like this: a kind of protection against the tide, volatilization prevention, the high sealing cold pressing type packaging aluminium packing of ultraviolet radiation preventing, comprise the bonding aluminium foil of plastic membranous layer, bonding more afterwards PVC rete, it is characterized in that: it also comprises the intermediate adhesion layer of inserting between plastic membranous layer and the aluminium foil layer, this intermediate adhesion layer is intersected by plastic membranous layer and aluminium foil and is bonded, and all plastic membranous layers and aluminium foil all be to intersect bondingly, and wherein plastic film is up to the plastic material because of coefficient.
The present invention compared with prior art has following good effect:
Multilayer is bonding, to mould plastic-aluminum aluminium PVC bonding or more multi-layered bonding because the present invention adopts in recombination process, can make to mould and bondingly between the aluminium adhere to mutually, complementary not enough, form multi-layer sealed, packaging product after the shaping not only can reach the performance and the quality of external like product, and strong more more withstand voltage than external like product, bigger toughness and pulling force have more high leakproofness and cost performance.The present invention utilizes up to the plastic film because of coefficient and arranges in pairs or groups with the composite film of the bonding formation of aluminium foil, can make and mould the aluminium membrane material and enter gold and mould state, coordinated is slowed down the destruction of lattice sliding deformation in the aluminium foil punching press drawing process, the plasticity of both elongations is reached substantially reach unanimity.Make it to be combined into the hard sheet of composite packaging of tough crisp complementation.Thereby overcome have only that the nylon adhesive aluminium foil just can finish and solve that the hard sheet of packaging aluminium strikes out that various concavities bubble at the moment easily breaks, the technology prejudice of layering, wrinkling and delamination.It is high fundamentally to have broken through the hard sheet price of external like product packaging aluminium, the monopoly position that monopolizes the market.Packaging product after the shaping not only can reach the performance and the quality of external like product, and strong more more withstand voltage than external like product, bigger toughness and pulling force.The present invention adopts the cheap MULTILAYER COMPOSITE of moulding aluminium film and aluminium foil, and the cost of comparing external like product packaging aluminium has reduced more than 40%.Can make that packaging aluminium shaping packaging process is difficult for breaking, comes off, tomography and distortion.Can make medicine good airproof performance, ultraviolet radiation preventing, the anti-property of medicine volatilization of packing.The resistant to elevated temperatures full-bodied intermediate connecting layer that the present invention adopts in recombination process makes that the packaging product after being shaped has more high leakproofness, and cost performance is better than external like product, and the ton price is lower, and the time cycle is shorter, and delivering goods from ordering goods to only needs 15 days.Can make medical manufacturer reduce tens thousand of units ton price cost and production cycle several months, improve the production efficiency of manufacturer, can save a large amount of foreign exchanges.
