Abstract
The utility model relates to an electromagnetic induction composite aluminum foil sealing gasket which comprises an aluminum foil layer, wherein a printed sealing layer is compounded on the upper surface of the aluminum foil layer, and an adhesive sealing layer is compounded on the lower surface of the aluminum foil layer. As the electromagnetic induction composite aluminum foil sealing gasket only consists of the aluminum foil layer, the printed sealing layer on the upper surface and the adhesive sealing layer on the lower surface, a paperboard layer and an adhesive layer between the paperboard layer and an aluminum foil are omitted, thereby being incapable of generating polluting gas during the sealing process, reducing the environmental pollution, simultaneously eliminating the pollution to foods and drugs caused by the residues of an adhesive on the sealing gasket, being conductive to reducing the cost as the paperboard layer is omitted, and being characterized by environmental protection, sanitation and energy conservation without reducing the sealing effect.
Description
Technical field
The utility model belongs to field of packaging material, particularly the joint filling material of medicine and food packaging bottle.
Background technology
In the can or bottle packing of food and medicine, adopt electromagnetic induction aluminium foil pad to seal usually and realize sealing, reaching prolongation food and the purpose of medicine shelf-life to intercept air and moisture.Such as the Chinese utility model patent (patent No.: 95244999.4) disclose the compound inner cap of a kind of aluminium foil paper mold, it is made up of foil laminated film and paper mold, aluminium foil and paper mold are bonded as one by adhesion agent, and the aluminium foil surface coating adhesive forms sealing film and forms foil laminated film.Its defective is that the direct printing effect of aluminium foil surface is relatively poor, and the aluminium foil density is not enough simultaneously, and sealing property is not fine.In order to overcome this defective, the applicant has applied for " a kind of electromagnetic inductive composite aluminum foil pad that is used for air-tight bottle class opening " (patent No.: 01240516.7), constitute by the adhesive phase bonding by substrate layer and aluminium foil layer, its key is to be coated with the sealing rete at the aluminium foil layer upper surface, and lower surface is coated with tack coat.Owing to covered the sealing rete, stopped up the micropore of aluminium foil surface, thereby had remarkable protection against the tide, air impermeability and advantages such as health, Theft-proof and anti-counter attractive in appearance at the aluminium foil layer upper surface.
The gasket seal of above-mentioned four layers or five-layer structure, all has cardboard, play buffering bottleneck gap, adopt hot melt adhesive and bonding foil together, defective is: lining cement volatilization contaminated environment when electromagnetic induction seals, not environmental protection, simultaneously, aluminium foil upper surface sealing residual lining cement of rete and Wax can produce pollution to medicine and food.
Summary of the invention
The utility model purpose is to improve the defective of existing electromagnetic induction aluminium foil pad, designs the simpler electromagnetic inductive composite aluminum foil seal gasket of a kind of structure, pollutes to reduce.
Specifically, electromagnetic inductive composite aluminum foil seal gasket has aluminium foil layer, and it is to be compounded with the printing and sealing layer at the aluminium foil layer upper surface, at aluminium foil layer lower surface compound sticking sealing layer.
Aluminium foil layer upper surface printing and sealing layer thickness is the 4-6 silk.
The utility model is owing to only be made of aluminium foil layer, upper surface printing and sealing layer, lower surface bonds sealing layer, omitted the adhesive linkage between ply of board and it and the aluminium foil, therefore, can not produce dusty gas in the process of sealing, and reduced the pollution to environment; Eliminated the residual pollution of lining cement on the seal gasket simultaneously to food and medicine; Reduced in addition and help behind the ply of board cost to reduce, have environmental protection, health, energy-conservation characteristics, and sealing effectiveness has not reduced.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Provided laminar texture figure of the present utility model as figure.Electromagnetic inductive composite aluminum foil seal gasket has aluminium foil layer 1, and it is compounded with printing and sealing layer 2 at aluminium foil layer 1 upper surface, at aluminium foil layer 1 lower surface compound sticking sealing layer 3.Aluminium foil layer 1 upper surface printing and sealing layer thickness is the 4-6 silk.Printing and sealing layer 2 is generally selected non-toxic material such as BOPP, PET, PE or PS for use; Compound sticking sealing layer 3 is selected the material consistent with the Packaging Bottle gate material for use, such as PC, PS, PP, PE or PET.Because now food and pharmaceutical agent moiety adopt glass bottle packaging, and glass is heated and can't realizes that heat melts bondingly, therefore, applies one deck glass cements (BL) as adhesive linkage at bonding sealing layer 3 lower surfaces.
Claims (3)
1. electromagnetic inductive composite aluminum foil seal gasket has aluminium foil layer (1), it is characterized in that being compounded with printing and sealing layer (2) at aluminium foil layer (1) upper surface, at aluminium foil layer (1) lower surface compound sticking sealing layer (3).
2. electromagnetic inductive composite aluminum foil seal gasket according to claim 1 is characterized in that aluminium foil layer (1) upper surface printing and sealing layer thickness is the 4-6 silk.
3. electromagnetic inductive composite aluminum foil seal gasket according to claim 1 and 2 is characterized in that applying one deck glass cement at bonding sealing layer (3) lower surface.
