发明名称 Sealing member for toner cartridge
摘要 The present invention provides a sealing film for a toner cartridge. The sealing film includes a layer with a preferred linear tearing direction. The layer is provided with longitudinal surface elements defining a strip to be torn out. The longitudinal surface elements extend in an inclined direction with respect to the strip to be torn out. The strip to be torn out includes a pulling means having a sufficient tearing resistance for preventing a separation between the pulling means and the strip to be torn out during a tearing operation.
