Abstract
A plastic-aluminum composite material for liquid food soft packing paper backing comprises a surface heat sealing layer, a printing ink layer, paper, a binding resin layer, aluminum foil, a binding resin layer and an inner heating layer, the seven layers material are serially-arranged from the outside to the inside. A surface binding resin layer is added between the surface heat-sealing layer and the printing ink layer, thereby enhancing binding effect. Through the selection of the outer layer improved L D P E layer with lower fusing point, the bottle filling efficiency of downstream is enhanced. Two binding resin layers are arranged between the paper and the aluminum foil, thereby achieving the purpose of better bonding force between the paper and the binding resin layer, also between the aluminum foil and the binding layer.
Description
Technical field
The utility model belongs to the packing of liquid beverage, a kind of specifically liquid food flexible packaging paper substrate aluminium plastic composite material.
Background technology
China's milk industry, the flexible packing material that beverage industries uses, once once monopolized by overseas enterprise, the polynary paper substrate aluminium plastic composite material of China Patent No. 2005200829020 liquid food aseptic packagings, disclose by modification LDPE, ink lay, paper, binding resin, aluminium foil, binding resin, the flexible packing material that modification LDPE seven layer materials are compound, reach every index of China's national standard, the surface layer modification LDPE layer of its ink lay outside should bonding ink lay, seal again, it will have certain peel strength and thicknesses of layers, possesses certain heat-sealing temperature again, and higher heat-sealing temperature, influence the can efficient in downstream, so the modification LDPE of this layer is after taking the heat-sealing effect into account, the peel strength of it and ink lay just is weak; Paper is different to the combination degree of binding resin with aluminium foil, and common a kind of binding resin is difficult to be satisfied with simultaneously paper and the requirement of aluminium foil desired binding.
Summary of the invention
The technical problems to be solved in the utility model is, overcomes the relatively poor shortcoming of above-mentioned binding force, and a kind of liquid food flexible packaging paper substrate aluminium plastic composite material of excellent bonding performance is provided.
The utility model is at the above-mentioned technical matters that will solve, the technical scheme that adopts is: a kind of liquid food flexible packaging paper substrate aluminium plastic composite material, comprise by tactic surface layer hot sealing layer 1, ink lay 2, paper 3, binding resin layer 4, aluminium foil 5, binding resin layer 6, nexine hot sealing layer 7 seven layer materials in outer the reaching, it is characterized in that increasing between surface layer hot sealing layer 1 and the ink lay 2 one deck surface layer binding resin layer 8.
Added surface layer binding resin layer 8, mainly realize with the bonding effect of ink lay 2 by surface layer binding resin layer 8, satisfy the demand of the bonding effect of raising surface layer binding resin layer 8 and surface layer heat-sealing 1, ink lay 2 interlayers during selection easily, equally, 1 of surface layer hot sealing layer needs to select to guarantee the material of its heat-sealing effect, and can utilize suitable selection that the melt temperature of surface layer hot sealing layer 1 is reduced or allow to select for use melt temperature lower, reach the purpose that improves downstream can efficient.Although added surface layer binding resin layer 8, because surface layer hot sealing layer 1 has had more choice, often the total cost of materials can be reduced on the contrary.
Between surface layer hot sealing layer 1 and the ink lay 2, between paper 3 and the aluminium foil 5, by binding resin layer 8, adhering resin layer 4 and adhering resin layer 6 that material at opposite sides is bonding compound respectively between aluminium foil 5 and the nexine hot sealing layer 7.
Surface layer binding resin layer 8 is the low density polyethylene (LDPE)s with binding power.
Between paper 3 and the aluminium foil 5 by binding resin layer 4 and 9 two-layer composition of binding resin layer.Binding resin layer 4 and binding resin layer 9 can be easy to select, and make them with paper 3, aluminium foil 5 bonding properties preferably be arranged respectively, simultaneously binding resin layer 4 and binding resin layer 9 well combination again.
Surface layer hot sealing layer 1, binding resin layer 8, ink lay 2, paper 3, binding resin layer 4, binding resin layer 9, aluminium foil 5, adhering resin 6 and nexine hot sealing layer 7 are bonding in order compound.
Surface layer hot sealing layer 1 and nexine hot sealing layer 7 all adopt modification LDPE material.
The utility model has the advantages that: increased surface layer binding resin layer at surface layer hot sealing layer and ink lay, mainly realize with the bonding effect of ink lay by surface layer binding resin layer, the surface layer hot sealing layer mainly is to guarantee its heat-sealing effect, the institute so that between composite layer bonding effect improved, more likely by selecting suitable surface layer binding resin layer, allow the melt temperature reduction of outer modification LDPE layer or select the lower outer modification LDPE layer of melt temperature for use, improve the can efficient in downstream.Two-layer binding resin layer is arranged between paper and the aluminium foil, and they are bonding with paper, aluminium foil respectively, have realized with paper, aluminium foil the purpose of binding power preferably being arranged all.
