Description
Technical field
The utility model is related to a kind of composite membrane, especially a kind of positioning coating paper aluminum composite membrane.
Background technology
With the development of the times, requirement of the people for food packaging is higher and higher, shows two sides of appearance and performance
Face.But existing packaging external appearance is not beautiful enough, barrier property is poor, heat sealability is bad, of high cost.
Utility model content
To solve the above problems, the utility model, which provides one kind, can be beautifully printed that pattern, barrier property be good, heat sealability
A kind of good, positioning coating paper aluminum composite membrane at low cost, specific technical solution are：
A kind of positioning coating paper aluminum composite membrane, including be close to successively positioning glue-line, substrate printing film layer, printing layer,
Upper adhesive layer, paper layer, lower adhesive layer, aluminium foil layer and leaching membrane layer.
Preferably, the substrate printing film layer is PET film layer, and thickness is 6 ~ 15 μm.
Preferably, the adhesive spread of the upper adhesive layer is 1.5 ~ 2.5g/m2。
Preferably, the thickness of the leaching membrane layer is 20 ~ 40 μm.
Preferably, the positioning glue array arrangement of the positioning glue-line, that is, the positioning glue for positioning glue-line are in strip shape coating, item
The positioning glue of shape is equidistantly coated on substrate printing film layer.
Preferably, the positioning glue is hot melt adhesive.
Position glue-line：Positioning glue is hot melt adhesive, and packaging seal heat-sealing effect can guarantee the good heat-sealing in the face A/A, A/B；It is fixed
Position glue array coating ensures that the maximum of heat-sealing region utilizes, does not waste hot melt adhesive, reduce cost.
Substrate printing film layer：Using PET film, thickness is 6 ~ 15 μm, and printing surface dyne is worth 38 or more, is positioning heat
The bearing bed of melten gel and the basal layer of printing layer, printing effect is good, and crystallinity is high, and transparency is good, not easily stretchable.
Upper adhesive layer：Double-component aqueous adhesive, coating weight is in 1.5 ~ 2.5g/m2Between, printing layer and paper layer are bonded,
Bonding intensity is good, and transparency is high, not easy to foaming, does not influence the printing effect in printing layer.
Paper layer：The thickness for increasing wrapping paper, makes product be more prone to fold, increases the top grade of product.
Lower adhesive layer：Connect paper layer and aluminium foil layer.
Aluminium foil layer：Barrier property is played, the oxygen barrier effect that blocks water is good.
Leaching membrane layer：20 ~ 40 μm of lamination thickness, is matched by polyethylene and slipping agent, and friction coefficient is low, and it is smooth to walk machine.
The utility model has the advantages that compared with prior art：
The pattern provided by the utility model that can be beautifully printed, with excellent barrier property, to walk machine smooth；Position glue-line
Common heat sealability film, A/B, B/B heat sealability for not only having had finished product can be replaced to be also greatly reduced cost of material.
Figure of description
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
In conjunction with attached drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of positioning coating paper aluminum composite membrane, including positioning glue-line, the substrate printing film be close to successively
Layer 1, printing layer 2, upper adhesive layer 3, paper layer 4, lower adhesive layer 5, aluminium foil layer 6 and leaching membrane layer 7.
10 array arrangement of positioning glue of glue-line is positioned, that is, the positioning glue 10 for positioning glue-line is in strip shape coating, strip
Positioning glue 10 is equidistantly coated on substrate printing film layer 1.The positioning glue 10 for positioning glue-line is hot melt adhesive, packaging seal heat-sealing
Effect, can guarantee the good heat-sealing in the face A/A, A/B；The coating of 10 array of glue is positioned, ensures that the maximum of heat-sealing region utilizes, does not waste
Hot melt adhesive reduces cost.
Substrate printing film layer 1 is PET film layer, and thickness is 6 ~ 15 μm.Printing surface dyne is worth 38 or more, is positioning heat
The bearing bed of melten gel and the basal layer of printing layer 2, printing effect is good, and crystallinity is high, and transparency is good, not easily stretchable.
The adhesive of upper adhesive layer 3 is double-component aqueous adhesive, and coating weight is in 1.5 ~ 2.5g/m2Between, bonding printing
Layer 2 and paper layer 4, bonding intensity is good, and transparency is high, not easy to foaming, does not influence the printing effect in printing layer 2.
Paper layer 4 increases the thickness of wrapping paper, makes product be more prone to fold, increases the top grade of product.
Lower adhesive layer 5 connects paper layer 4 and aluminium foil layer 6.
Aluminium foil layer 6 plays barrier property, and the oxygen barrier effect that blocks water is good.
The lamination thickness of leaching membrane layer 7 is 20 ~ 40 μm, is matched by polyethylene and slipping agent, friction coefficient is low, and it is suitable to walk machine
Freely.
