Abstract
The utility model relates to an aluminum film composite double-layered air cushion film, which comprises an aluminum film layer, and is characterized by comprising an air cushion film layer, wherein the surface of an air cushion film layer closed airbag is provided with a film layer; the aluminum film composite double-layered air cushion film compounds the aluminum film with the air cushion film,overcomes the defects that the aluminum film has strong heat conductivity and is easy to break, and the defect that the air cushion film is easy to tear, is used for packing food, and has the advantages of no toxin, no harm, high-barrier, good heat and cold insulating performance and the like.
Description
Technical field
The utility model relates to the film that is used for packaged food, says in detail to relate to a kind of aluminum film compounded double-layer air bubble film, belongs to the packaging for foodstuff field.
Background technology
Because food package film has convenient carrying, meets modern people life style efficiently, is widely used in recent years thus.But require to possess following feature for the digestion resistant food package film: (1), meet food security, nontoxic to human body; (2), heat sealability is good, chemical stability is good, with soda acid salt solvent, grease chemical reaction does not take place; (3), fragrance of steam, food flavor, condiment product etc. there is higher barrier; (4), high temperature resistant.
People adopt Vingon (PVDC) to make the material of thermophilic digestion and packing always for many years, but enhancing along with food health consciousness, environmental consciousness, some developed countries have begun to ban use of the material of chloride ion-containing to make the contact packaging material of food, the begin one's study substitute of PVDC of people.
The aluminium film is the packaging material for food of a new generation of developing of people, has high barrier, characteristics such as high temperature resistant, safe in utilization, but still has a lot of shortcomings, as: aluminium film mechanical strength is not high, be subjected to the fold frangibility and crackle occurs, easily tear, fracture, make the barrier forfeiture.
Air-cushion film claims bubble chamber film again, is to adopt the high-quality polyvinyl resin to process, and also is the current a kind of packaging material that generally use, and is of many uses.Because the air-cushion film intermediate layer is full of air, so body is light, high resilience, have heat insulation, every cold performance.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of aluminum film compounded double-layer air bubble film, has high barrier, and heat insulation every cold.
The utility model is achieved through the following technical solutions:
A kind of aluminum film compounded double-layer air bubble film comprises aluminum membranous layer, it is characterized in that also comprising foaming rete and thin layer.
Between described layer structure, can increase tack coat as required, to guarantee the inequality or not akin combined strength bination between two-layer of polarity.
Described tack coat is polyethylene (PE) layer.
In described layer structure, the adhesive that can exist one deck to be used to bond between layer and the layer if the polarity of adjacent two layers is identical, also can not increase adhesive, and is only compound by modes such as hot melts.
Described air bubble film is by being traditional air-cushion film.
The beneficial effects of the utility model are: the utility model combines aluminium foil and air bubble film, use the PE layer between two-layer and make tack coat, guaranteed intensity, and possessed the advantage of two kinds of packaging material simultaneously, it is too strong to have overcome aluminium film thermal conductivity, the shortcoming that air bubble film is easy to be torn, on the air cushion rete, increasing thin layer again, increased lifting surface area, avoided indivedual air bags of air bubble film to be easy to the shortcoming of being swarmed in, be used for packaged food have nontoxic, high-barrier, heat insulation every advantages such as cold property are good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail:
With reference to shown in Figure 1, aluminum film compounded double-layer air bubble film described in the utility model comprises aluminum membranous layer 1, and air cushion rete 2 is at the surface recombination film of the airtight air bag of described air-cushion film
Described air-cushion film is by being traditional bubble chamber film.
Combination between the different layers is: between aluminium film and the air-cushion film, at first drenching film at aluminium film surface handles, sided corona treatment then, increase adhesion between them by electric shock, be coated with adhesive at aluminium film surface then, be combined with each other through compounding machine and air bubble film hot melt dry method, air bubble film and thin layer combine by hot melt, rolling then.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
Claims (2)
1, a kind of aluminum film compounded double-layer air bubble film comprises aluminum membranous layer, it is characterized in that also comprising the air cushion rete.
2, aluminum film compounded double-layer air bubble film according to claim 1 is characterized in that in the airtight balloon surface of described air bubble film layer the PE layer being arranged, described aluminum film compounded air bag envelope gas-bearing formation at air-cushion film.
