Abstract
The invention discloses a kind of reinforced aluminium plastic film; including: the first aluminium foil composite bed, the middle enhancement Layer being bonded on the first aluminium foil composite bed inner surface and the second aluminium foil composite bed being bonded on middle enhancement Layer inner surface; described first aluminium foil composite bed includes the first protective layer and the first aluminium foil layer being bonded on the first protective layer inner surface, and described second aluminium foil composite bed includes the second protective layer, the second aluminium foil layer and the hot sealing layer arranged that bond the most successively.By the way, intensity of the present invention is high, and puncture resistance is good, has the water vapor barrier property of excellence.
Description
Technical field
The present invention relates to encapsulating material technical field, particularly relate to a kind of reinforced aluminium plastic film.
Background technology
The most easily discharging gas for current rigid pack lithium battery, pressure increase causes explosion issues, city
Starting novel flexible packing material-aluminum plastic film occur on face, soft package lithium battery structurally uses laminated aluminum film, and safety is occurring
In the case of hidden danger, soft package lithium battery is the most only understood air-blowing and is split, and can explode unlike box hat aluminum hull battery core.Existing
This aluminum plastic film insufficient strength, puncture resistance is not good enough.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of reinforced aluminium plastic film, and intensity is high, and puncture resistance is good, tool
There is the water vapor barrier property of excellence.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of reinforced aluminium plastic film, bag
Include: the first aluminium foil composite bed, the middle enhancement Layer being bonded on the first aluminium foil composite bed inner surface and be bonded in middle enhancement Layer
The second aluminium foil composite bed on inner surface, described first aluminium foil composite bed includes the first protective layer and is bonded in the first protective layer
The first aluminium foil layer on surface, described second aluminium foil composite bed include boning the most successively arrange the second protective layer, the
Two aluminium foil layers and hot sealing layer.
In a preferred embodiment of the present invention, described middle enhancement Layer includes first arranged that bond the most successively
Mylar, middle nylon film and the second mylar.
In a preferred embodiment of the present invention, the thickness of described middle enhancement Layer is 60 ~ 80 μm.
In a preferred embodiment of the present invention, the thickness of described first aluminium foil layer is 30 μm, described second aluminium foil layer
Thickness is 50 μm.
In a preferred embodiment of the present invention, it is thin that described first protective layer and the second protective layer are Kynoar
Film.
The invention has the beneficial effects as follows: reinforced aluminium plastic film of the present invention, intensity is high, and puncture resistance is good, has excellence
Water vapor barrier property.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in embodiment being described below required for make
Accompanying drawing be briefly described, it should be apparent that, below describe in accompanying drawing be only some embodiments of the present invention, for
From the point of view of those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other according to these accompanying drawings
Accompanying drawing, wherein:
Fig. 1 is the structural representation of reinforced aluminium plastic film one of the present invention preferred embodiment.
In accompanying drawing, the labelling of each parts is as follows: 1, the first protective layer, the 2, first aluminium foil layer, the 3, first mylar, 4, in
Between nylon film, the 5, second mylar, the 6, second protective layer, the 7, second aluminium foil layer, 8, hot sealing layer.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described enforcement
Example is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiments that technical staff is obtained under not making creative work premise, broadly fall into the model of present invention protection
Enclose.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of reinforced aluminium plastic film, including: the first aluminium foil composite bed, the centre being bonded on the first aluminium foil composite bed inner surface add
Strong layer and the second aluminium foil composite bed being bonded on middle enhancement Layer inner surface.
Described middle enhancement Layer includes bond the most successively the first mylar 3 arranged, middle nylon film 4 and
Second mylar 5, it is higher strong that the thickness of described middle enhancement Layer is that 60 ~ 80 μm, mylar and nylon film are respectively provided with
Degree, described middle enhancement Layer is formed by two kinds of film combinations, and the advantage combining both effectively increases plastic-aluminum film strength.
Described first aluminium foil composite bed includes the first protective layer 1 and the first aluminium foil being bonded on the first protective layer inner surface
Layer 2, described second aluminium foil composite bed includes bond the most successively second protective layer the 6, second aluminium foil layer 7 arranged and heat-sealing
Layer 8.
Preferably, the thickness of described first aluminium foil layer 2 is 30 μm, and the thickness of described second aluminium foil layer 7 is 50 μm, barrier
Good.
Preferably, described first protective layer and the second protective layer are polyvinylidene difluoride film.
The invention has the beneficial effects as follows: reinforced aluminium plastic film of the present invention, intensity is high, and puncture resistance is good, has excellence
Water vapor barrier property.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description is made convert, or are directly or indirectly used in other relevant technology neck
Territory, is the most in like manner included in the scope of patent protection of the present invention.
