At present, the technology of the lithium ion battery is mature day by day, and the soft package aluminum plastic film is widely applied to the fields of 3C electronic products, power batteries, energy storage and the like due to the advantages of light weight, safety and the like. In the processing process, because the internal stress of the nylon film in the soft-package aluminum-plastic film is greater than that of the polypropylene film, the soft-package aluminum-plastic film is easy to warp, and a leveling procedure is required to be added in severe cases, so that the working efficiency can be greatly reduced.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention is directed to the defects in the prior art, and the main object of the present invention is to provide an improved high internal stress multilayer body for an aluminum-plastic film, which can avoid the warpage of a soft-packaged aluminum-plastic film, and can improve the working efficiency without increasing the leveling process.
In order to achieve the purpose, the utility model adopts the following technical scheme:
an improved high internal stress multilayer body for an aluminum plastic film comprises an FEP base material layer, a glue layer and a sealing layer, wherein the glue layer and the sealing layer are respectively arranged on the upper surface and the lower surface of the FEP base material layer, and the sealing layer is an ethylene-propylene copolymer film layer.
Preferably, the thickness of the FEP base material layer is 18-72 μm.
As a preferable scheme, the thickness of the glue layer is 3-18 μm.
Preferably, the thickness of the sealing layer is 3-18 μm.
Preferably, the glue layer is a maleic anhydride grafted polypropylene resin film layer.
Preferably, the glue layer and the sealing layer have the same thickness, and the ratio of the thicknesses of the sealing layer and the FEP base layer ranges from 1/8 to 1/3.
Compared with the prior art, the utility model has obvious advantages and beneficial effects, and particularly, according to the technical scheme, the FEP substrate layer is arranged, so that the internal stress can be improved, and the supporting effect is achieved, so that the warping phenomenon of the soft package aluminum plastic film can be avoided, the leveling process is not required to be added, and the working efficiency can be improved.
To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
