Abstract
The utility model discloses a high resistant separates electromagnetic induction and seals gasket, including thermal -insulated rete, plastic -aluminum rete and the back sheet of sealing of high resistant, the back sheet is the cardboard, and the plastic -aluminum rete is glued compoundly on the back sheet through weak viscidity, and the thermal -insulated rete complex of sealing of high resistant is on the plastic -aluminum rete. The utility model discloses an one is waterproof, the thermal -insulated rete that seals of anticorrosion high resistant, and the sealing performance of gasket, preventing leakage are sealed in the reinforcing.
Description
Technical field
This utility model relates to a kind of seal gasket, particularly to a kind of high-barrier electromagnetic induction seal gasket.
Background technology
Nowadays, demand according to people, a lot of aspects in productive life are directed to the packaging of article, such as medical medicine, chemical drugs and food etc., it is required for packing, to avoid the article of encapsulation to be polluted by external substance, or prevent dangerous things leakage from working the mischief and losing.
When packaging, to be packaged at container closure be packaging emphasis, a kind of electromagnetic induction seal gasket of many employings in prior art, it is by plastic foil, aluminum paper tinsel, cardboard, foaming different materials is composited, plastic foil is heat sealability plastic foil, heat sealability plastics constitute the seal layer bonding with bottle cap, aluminium foil forms aluminium foil layer, cardboard and expanded material are backing layer, seal layer, aluminium foil layer and backing layer are sequentially stacked to be combined with each other, according to different bottleneck materials, after using corresponding heat-sealing plastic foil compound with aluminium foil, by electromagnetic induction, aluminium foil is generated heat, so that seal layer is closely linked with bottleneck, reach sealing effectiveness；
But this kind of seal gasket there is also following defect: when bottle is built with the material that corrosivity and permeability are stronger, heat sealability plastic foil still can be corroded, and causes existing seal layer to be difficult to these materials and intercepts, it is easy to causes inclusions to leak.
In order to overcome disadvantages mentioned above, seal gasket is improved by the present inventor, and especial manufacture goes out a kind of high-barrier electromagnetic induction seal gasket, and this case thus produces.
Utility model content
The purpose of this utility model is to provide a kind of high-barrier electromagnetic induction seal gasket, and it is waterproof by one, and anticorrosion high-barrier heat-sealing film layer strengthens the sealing property of seal gasket, prevents from revealing.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of high-barrier electromagnetic induction seal gasket, including high-barrier heat-sealing film layer, aluminum plastic film layer and backing layer, backing layer is cardboard, and aluminum plastic film layer is compounded on backing layer by weak viscosity glue, and high-barrier heat-sealing film layer is compounded on aluminum plastic film layer.
Described high-barrier heat-sealing film layer is adhesive.
After using such scheme, the high-barrier hot blast film layer with strong water proofing property and anticorrosive property is compounded on aluminum plastic film layer by this utility model, aluminum plastic film layer is made high-barrier hot blast film layer together with mouth bonding by electromagnetic induction heating, in avoiding bottle, material corrodes the problem that pad causes revealing, the sealing of reinforced gasket.
Accompanying drawing explanation
Fig. 1 is profile of the present utility model；
Label declaration
High-barrier heat-sealing film layer 1, aluminum plastic film layer 2, backing layer 3.
Detailed description of the invention
As shown in Figure 1, a kind of high-barrier electromagnetic induction seal gasket that this utility model discloses, including high-barrier heat-sealing film layer 1, aluminum plastic film layer 2 and backing layer 3, backing layer 3 is cardboard, aluminum plastic film layer 2 is composited by aluminizer and heat-sealing plastic foil, aluminum plastic film layer 2 is compounded on backing layer 3 by weak viscosity glue, and high-barrier heat-sealing film layer 1 is compounded on aluminum plastic film layer；Described high-barrier heat-sealing film layer uses adhesive, adhesive type is a lot, in the present embodiment, adhesive is formed by the configuration of EMMA resin, EVA resin, microwax and Colophonium, after these material mixing at high temperature melt, stir the adhesive obtained, being applied on aluminum plastic film, substituted for original heat-sealing plastic membranous layer, aluminum plastic film layer is made adhesive and mouth bonding by electromagnetic induction heating, possessing excellent waterproof and anticorrosive property, barrier property ratio is higher.
Therefore, this utility model replaces plastic hot sealer layer by the high-barrier heat-sealing film layer of high obstructing performance, it is possible to avoids strong corrosive material to permeate, improves the sealing of pad.
These are only specific embodiment of the utility model, not the restriction to protection domain of the present utility model.All equivalent variations done according to the mentality of designing of this case, each fall within the protection domain of this case.
