In [Equation 1], A is a value obtained by dividing a thickness of the metal layer by a total thickness of the secondary battery pouch film, B is a value obtained by dividing a thickness of the metal layer by a thickness of the sealant layer, and C is a value obtained by dividing a thickness of the extruded polypropylene (PP) layer of the sealant layer by a thickness of the cast polypropylene (CPP) layer of the sealant layer. The pouch film has excellent formability, curling, insulation, bending, and peel strength.

Abstract: Disclosed is a cell pouch having excellent formability, which includes a high elongation nylon film. When the high elongation nylon film is stretched in a machine direction (MD), an increment of a tensile strength value with respect to an increment of an elongation value (an increment of tensile strength/an increment of elongation) increasing from 6.7% to 100% is more than 0.04 and less than 0.05, and when the high elongation nylon film is stretched in a transverse direction (TD), an increment of a tensile strength value with respect to an increment of an elongation value increasing from 6.7% to 100% is more than 0.06 and less than 0.08.

Abstract: Cell packaging according to one embodiment of the present invention comprises: a base film layer; and a print layer provided beneath or on the base film layer, and including a binder resin and carbon black. The base film layer or print layer of the cell packaging is partially removed by means of laser irradiation to expose the layer under same. Therefore, according to the cell packaging of the invention, a wide range of shapes or logos, etc. can easily be externally displayed so as to be discernible by means of laser irradiation. By thus imparting discernibility and externality to the cell packaging, a labeling process for attaching a separate label to the cell packaging can be excluded.

Abstract: Disclosed is a surface protective film, a method for fabricating the same, and pouch, and a method for fabricating the same. The surface protective film includes a stack of films including a middle layer, and a first skin layer and a second skin layer on opposite sides of the middle layer, wherein at least one of the first skin layer and the second skin layer is formed of a resin having a hardness lower than a hardness of a surface to be protected by the surface protective film, and the middle layer is formed of a resin including high density polyethylene, thereby permitting protection of a display surface without formation of scratch at a very low cost compared to the related art without aging and with slip.

Abstract: Provided is a cell packaging material having a layered structure of one or more layers, wherein at least one layer includes a flame retardant, a coating layer imparted with flame resistance, or both. In the cell packaging material, a cell itself does not include any flame resistant film or flame retardant. Therefore, it is possible to provide a cell with flame resistance while not increasing the cell volume or not affecting the cell operation.
