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 packaging aluminium calendaring molding easily breaks during dark bubble-cap more than 7 millimeters, the technology prejudice of layering, wrinkling and delamination, a kind of employing MULTILAYER COMPOSITE principle is provided, can make and mould the aluminium membrane material and enter gold and mould state, coordinated constitutes the MULTILAYER COMPOSITE hermetically-sealed construction, form multi-level leak free, strong more withstand voltage, have more the high sealing hot belt type packaging aluminium of leak tightness.
The object of the present invention is achieved like this: a kind of protection against the tide, volatilization prevention, the high sealing hot belt type packaging aluminium of ultraviolet radiation preventing, it comprises that plastic membranous layer replaces the compound aluminium of moulding that bonding aluminium foil is formed, last coating adhesive, it is characterized in that: it is more than four layers or four layers that plastic film and aluminium foil replace the bonding number of plies, and described plastic film is up to the plastic film because of coefficient.
The present invention compared with prior art has following good effect:
Because to adopt multilayer to mould plastic-aluminum aluminium in recombination process bonding or more multi-layered bonding in the present invention, can make to mould and bondingly between the aluminium adhere to complementary deficiency mutually.Utilized and moulded the tough crisp complementarity of aluminium, especially up to composite film collocation because of the plastic film of coefficient and the bonding formation of aluminium foil, slowed down the destruction of lattice sliding deformation in the aluminium foil punching press drawing process, made the plasticity of both elongations reach the synchronous forming technique effect that reaches unanimity substantially.Thereby the hard sheet of the composite packaging that is combined into tough crisp complementation, the toughness of composite film and tensile strength, stretch ratio and plasticity are higher than external series products.Overcome not only up to MULTILAYER COMPOSITE that aluminium foil is strong easily to be split because of coefficient plastic film and aluminium foil, metal and metal be the hard fragility problem that produces of high density composite and MULTILAYER COMPOSITE directly, and overcome have only aluminium, nylon adhesive aluminium foil just can finish and solve when the hard sheet of packaging aluminium strikes out dark bubble-cap more than 7 millimeters at present easily to break, the technology prejudice of layering, wrinkling and delamination.Solve this packaging aluminium that present domestic none producer can solve and be difficult to the technical barrier broken through in thickness, color, surface gloss, compound toughness, anti-peel force five greatly.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, and bigger toughness and pulling force have more high leakproofness and cost performance.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 articulamentum that the present invention adopts in recombination process makes the packaging product after being shaped have more high leakproofness.The present invention adopts the MULTILAYER COMPOSITE of cheap plastic film and aluminium foil to replace two layers of composite structure of nylon adhesive aluminium foil of external like product,, reduced more than 40% than the cost of two layers of composite structure packaging aluminium of nylon adhesive aluminium foil of external like product.Cost performance obviously 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.
