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.
