Abstract
The invention discloses an electromagnetic induction sealing gasket with an acting component, a manufacturing method and a sealing method. The electromagnetic induction sealing gasket is formed by compositing a plurality of layers of materials, namely a heat-sealing layer, an aluminum foil layer, a heat-insulating layer, a folded film layer and a top film layer from bottom to top in sequence; and the layers are glued together. According to the invention, the aluminum foil layer is heated by electromagnetic induction and transmits heat to the heat-sealing layer to smelt the heat-sealing layer to achieve an adhesive bottleneck sealing effect. The acting component formed after sealing comprises two glued layers of PET films, can allow removing the gasket left or right or in any direction, is very firm and is difficult to break. The manufacturing method can realize integral forming and is suitable for automatic industrial production. The electromagnetic induction sealing gasket is applicable to bottleneck sealing in the fields of medicines, health-care products, foodstuff, seasonings, cosmetics, washing products and the like, radically solves the problem that a conventional bottleneck sealing gasket is difficult to remove, and has a wide application prospect.
Description
Technical field
The present invention relates to seal gasket technical field, specifically, relate to a kind of electromagnetic induction seal gasket and manufacture method and sealing method.
Background technology
Seal gasket is more and more general in the use of industry-by-industry, as medicine, health products, food, seasonings, cosmetics, articles for washing etc.Current industrial most employing electromagnetic induction seal gasket; by electromagnetic induction sealing device, the aluminium foil layer of pad is carried out electromagnetic induction heating; make the plastic film melted by heat of pad and bottleneck contact surface; realize pad and bottle sealing; the material cut off in bottle face contacts with air, plays the effect of the material in protection bottle.
But current seal gasket all do not arrange can open pad put forth effort parts, or it is firm not to put forth effort parts, and this makes user very inconvenient when opening pad, and edge tool often will be used to cut pad, thus dangerous hidden danger.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, providing a kind of with putting forth effort parts and firm electromagnetic induction seal gasket.
To achieve these goals, the present invention adopts following technical scheme:
A kind of electromagnetic induction seal gasket, is composited by multilayer material, be successively from the bottom up hot sealing layer, aluminium foil layer, thermal insulation layer, film to fold and film top layer, bond through glue between each layer.
The effect of hot sealing layer is after melted by heat, play the effect of bonding bottle sealing.
Generate heat after the effect of aluminium foil layer is through electromagnetic induction, to hot sealing layer transferring heat, make hot sealing layer melt bonding bottleneck.
The effect of thermal insulation layer is: 1, isolated aluminium foil layer heat passes to film to fold and film top layer, and avoid film to be heated to fold and film top layer and to bond with plastic bottle lid, impact is uncapped.2, hot sealing layer is given and aluminium foil layer provides deflection, not curling after making coiled material puncher for spacer strip be cut into circle.3, by controlling the thickness of the adjustable whole pad of thickness of thermal insulation layer.
The effect of film to fold is: to pad carry out die-cut after, can be formed and put forth effort parts.What namely film became pad top to the semi-circular portions that fold and film top layer are fitted puts forth effort part.
As preferably, in above-mentioned electromagnetic induction seal gasket, the thin layer for strengthening deflection or thickness is set between aluminium foil layer and thermal insulation layer.
As preferably, in above-mentioned electromagnetic induction seal gasket, described film is polyethylene terephthalate (PET) or PEN (PEN) to the material of fold, film top layer or thin layer.
As preferably, in above-mentioned electromagnetic induction seal gasket, after glue bonding, between each layer, arrive the peel strength of more than 2N/10mm.
Another object of the present invention is to provide the manufacture method of above-mentioned electromagnetic induction seal gasket, comprises the steps:
Step 1: use dry compound machine to bond after the thin layer gluing of coiled material with aluminium foil layer, obtained first complex;
Step 2: by step 1 gained first complex, by bonding with hot sealing layer after dry compound machine gluing, obtained second complex;
Step 3: by the film of coiled material to fold and film top layer respectively through after gluing, bond with thermal insulation layer, obtained 3rd complex;
Step 4: after the second complex gluing of rolling, with the 3rd composite bodies, obtained electromagnetic induction seal gasket.
A further object of the present invention is to provide and utilizes above-mentioned electromagnetic induction seal gasket to carry out the method for sealing, comprise the steps: step 1: using the film of coiled material electromagnetic induction seal gasket to the broken line of fold as diameter, circular die is adopted to carry out die-cut, the obtained circular seal gasket putting forth effort parts with top;
Step 2: loaded towards bottle cap by the top layer of circular seal gasket, then pins bottleneck by the bottle cap with seal gasket; Finally use electromagnetic induction that aluminium foil layer is generated heat, transferring heat, to hot sealing layer, makes hot sealing layer melt bonding bottleneck and seals; Naturally, after cooling, unscrewing cap, catches and puts forth effort parts and just can open circular seal gasket.
Compared with prior art, the present invention has following beneficial effect:
Of the present invention with putting forth effort the electromagnetic induction seal gasket of parts by multilayer material compound, be successively from the bottom up hot sealing layer, aluminium foil layer, thermal insulation layer, film to fold and film top layer, after glue bonding, arrive the peel strength of more than 2N/10mm between each layer.Aluminium foil layer is generating heat after electromagnetic induction, and transferring heat, to hot sealing layer, makes hot sealing layer melt, and plays the effect of bonding bottle sealing.Then carry out die-cut by pad according to bottleneck size, die-cut rear film is raised formation to fold along broken line and is puted forth effort parts, and pulling is puted forth effort parts and just can be opened pad easily.The parts of putting forth effort formed after the sealing of this electromagnetic induction seal gasket are bonded by the two-layer PET film in left and right, to the left or to the right or arbitrarily can open pad in other directions, very firm, not frangibility.Manufacture method of the present invention can be one-body molded, is suitable for automatic industrial and produces.This electromagnetic induction seal gasket is applicable to the bottle sealing in medicine, health products, food, seasonings, cosmetics, articles for washing etc. field, thoroughly solves the problem that existing bottle mouth sealing pad is difficult to open, has a extensive future.
