Property heat-sealing internal layer between be provided with middle layer, adhesive layer, the middle layer are provided between the flexible cover sheet and middle layer
It is provided with special adhesion layer between flexible heat-sealing internal layer, middle layer and flexible heat-sealing internal layer can be made to be bonded together, and can
Certain isolation performance is provided, there is extremely strong anti-swelling.
Further, the flexible cover sheet with a thickness of 12 μm ~ 30 μm.
Further, the material of the flexible cover sheet is nylon membrane, polyethylene terephthalate film or poly- to benzene
Dioctyl phthalate butanediol ester film.
Further, the adhesive layer uses acrylic ester adhesive or polyurethane binder.
Further, the middle layer with a thickness of 20 μm ~ 60 μm.
Further, the material of the middle layer is polyimide film or poly (ethylene naphthalate) film.
Further, the special adhesion layer with a thickness of 5 μm ~ 50 μm.
Further, the material of the special adhesion layer is modified polypropene film.
Further, the flexible heat-sealing internal layer with a thickness of 5 μm ~ 80 μm.
Further, the material of the flexible heat-sealing internal layer is polypropylene film or polyethylene film.
It is using the beneficial effect of technical solution of the present invention:
It is proposed by the present invention to propose a kind of new flexible battery encapsulating material, applied to the encapsulation of flexible battery, have good
Good sealing insulating, and being applicable in existing battery manufacturing process, being made after battery can multiple curved material.
