Abstract
The utility model is open a kind of without viscose type electromagnetic induction seal gasket, comprises seal layer, strong viscosity glue-line, aluminium foil layer, weak viscosity glue-line and back sheet; Back sheet is cardboard, and weak viscosity glue-line is inviscid compound glue; By strong viscosity glue-line compound between seal layer and aluminium foil layer, by weak viscosity glue-line compound between aluminium foil layer and back sheet, seal layer, aluminium foil layer and back sheet are by strong viscosity glue-line and weak viscosity glue-line is sequentially stacked is combined with each other; The utility model is applied to packaging field, realizes aluminium foil layer noresidue glue, improves packaging quality and efficiency.
Description
Technical field
The utility model relates to a kind of seal gasket, particularly a kind of without viscose type electromagnetic induction seal gasket.
Background technology
Nowadays, according to the demand of people, the packaging of article is all related in a lot of in productive life, such as medical medicine, chemicals and food etc., all need to pack, with the pollution avoiding the article encapsulated to be subject to external substance, or prevent dangerous things leakage from working the mischief and losing.
When packing, encapsulate container closure place is the emphasis packed, a kind of electromagnetic induction seal gasket of many employings in prior art, it comprises seal layer, aluminium foil layer and back sheet, seal layer, aluminium foil layer and back sheet are sequentially stacked to be combined with each other, utilize electromagnetic induction that aluminium foil layer is generated heat, seal layer and bottleneck is allowed to combine closely thus to reach sealing effectiveness, the glue of weak sticky class is wherein adopted to meet between back sheet and aluminium foil layer, back sheet is thick layer cardboard, the glue of this weak sticky class is generally sticking wax (as microwax), this wax is meeting melting in high temperature sealing, then absorbed by cardboard, aluminium foil layer then stays bottleneck, cardboard is stayed inside bottle cap, thus reach the object of encapsulation bottleneck, bonnet upper bottle cover is sealed off in sealing, cardboard can also play certain press seal barriering effect.
There is following defect in above-mentioned battery induction seal gasket: makes its melting because needs carry out heating to wax layer, if there is time of heating and temperature not and the situation of paperboard structure denser, cardboard will be not exclusively to the absorption of wax, cause cardboard and aluminium foil layer inseparable, this kind of situation affects packing of product quality on the one hand, make packaging process need to drop into more energy for product examination, on aluminium foil layer, residual wax is made troubles to user on the other hand.
In order to overcome above-mentioned shortcoming, the present inventor improves seal gasket, and especial manufacture goes out a kind of without viscose type electromagnetic induction seal gasket, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of without viscose type electromagnetic induction seal gasket, and it is at aluminium foil layer without any removing residual glue, and aluminium foil layer is easily separated with cardboard, packaging process more fast, raising packed products rate.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of without viscose type electromagnetic induction seal gasket, comprise seal layer, strong viscosity glue-line, aluminium foil layer, weak viscosity glue-line and back sheet; Back sheet is cardboard, and weak viscosity glue-line is inviscid compound glue; By strong viscosity glue-line compound between seal layer and aluminium foil layer, by weak viscosity glue-line compound between aluminium foil layer and back sheet, seal layer, aluminium foil layer and back sheet are by strong viscosity glue-line and weak viscosity glue-line is sequentially stacked is combined with each other.
Described aluminium foil layer material is aluminum plastic film.
After adopting such scheme, inviscid compound glue of the present utility model (weak viscosity glue-line) is coated on cardboard (back sheet), aluminium foil layer and back sheet are combined with each other, after inviscid compound glue pressurized, there is slight viscosity, make aluminium foil layer and back sheet well bonding, aluminium foil layer can be made again to separate with back sheet when being subject to slight external force, in its separation process, inviscid compound glue is stayed on cardboard, aluminium foil layer can not remain inviscid compound glue, the utility model is by realizing the electromagnetic induction seal gasket without sticky formula to improvement bonding between aluminium foil layer with back sheet in electromagnetic induction seal gasket, improve packaging quality and efficiency.

Fig. 2 is the utility model use figure.
Label declaration
Seal layer 1, strong viscosity glue-line 2, aluminium foil layer 3, weak viscosity glue-line 4, back sheet 5.
Detailed description of the invention
As shown in Fig. 1 to 2, the one that the utility model discloses, without viscose type electromagnetic induction seal gasket, comprises seal layer 1, strong viscosity glue-line 2, aluminium foil layer 3, weak viscosity glue-line 4 and back sheet 5; Back sheet 5 is cardboard, and weak viscosity glue-line 4 is inviscid compound glue; By strong viscosity glue-line 4 compound between seal layer 1 and aluminium foil layer 3, by weak viscosity glue-line 4 compound between aluminium foil layer 1 and back sheet 5, seal layer 1, aluminium foil layer 3 and back sheet 5 are by strong viscosity glue-line 2 and weak viscosity glue-line 4 is sequentially stacked is combined with each other.
Aluminium foil layer 3 material adopts aluminum plastic film, and aluminum plastic film is better with the viscosity of inviscid compound glue laminating, and when inviscid compound glue is stressed, disengaging aluminum plastic film is easier.
When the utility model encapsulates bottleneck, heating aluminium foil layer 3 makes seal layer 1 and bottleneck combine closely, and strong viscosity glue-line 2 makes aluminium foil layer 3 and seal layer 1 keep compact siro spinning technology, and weak viscosity glue-line 4 makes aluminium foil layer 3 and back sheet 5 keep adhere less; During open bottle cover, cardboard (back sheet 5) departs from aluminium foil layer 3 with bottle cap, and inviscid compound glue is all stayed on cardboard, aluminum plastic film no longer leaves inviscid compound glue.
The utility model is a kind of realizes encapsulation mouth without adhesion without sticky formula electromagnetic induction seal gasket, avoid because of aluminum plastic film removing residual glue, and cause cardboard and the indissociable problem of aluminium foil layer 3, bottleneck after the opening again effective press seal of the available cardboard with glue intercepts, both packaging quality and efficiency had been improve, the sealing that can ensure that again Packaging Bottle is follow-up when using.
These are only specific embodiment of the utility model, the restriction not to protection domain of the present utility model.All equivalent variations done according to the mentality of designing of this case, all fall into the protection domain of this case.
