摘要： The present invention provides a film roll comprising an electrified portion at at least part in the transverse direction of a film that is wound into a roll, in which the difference between the maximum width and the minimum width of the electrified portion is 10 mm or less. In this manner, side slipping can be reliably prevented while securing escapeways for air at the edges, and a film roll having no side slips, wrinkles, deformation, decentering, or the like can be manufactured. The film roll of the present invention can be manufactured by intermittently electrifying the film at a predetermined cycle, the ratio of the time duration of the electrification in the cycle being 10 to 80%. The film roll of the present invention has a high adhesive force and does not suffer from slipping during evacuation in a vacuum evaporator. Thus, the film roll is suitable as a master roll for metallization and can be suitably applied to various uses such as magnetic tapes, packaging materials, capacitors, and the like.
摘要翻译：本发明提供一种胶片卷，其包括在卷绕成卷的薄膜的横向方向的至少一部分上的带电部分，其中带电部分的最大宽度和最小宽度之间的差为10mm以下。以这种方式，可以可靠地防止侧滑，同时确保边缘处的空气的空隙，并且可以制造没有侧滑，皱纹，变形，偏心等的薄膜辊。本发明的薄膜卷可以通过以预定的周期间歇地带电来制造，循环中的带电持续时间的比例为10〜80％。本发明的胶卷具有高粘合力，并且在真空蒸发器中抽真空期间不会发生滑动。因此，膜卷适合作为用于金属化的母辊，并且可以适用于各种用途，例如磁带，包装材料，电容器等。
