发明名称 Degradable slitted cigarette filter
摘要 A cigarette filter comprises an elongate filter component having a longitudinal axis. A plurality of spaced apart slits generally perpendicular to the longitudinal axis of the filter component partially extend into the component. The slits enable the filter to disintegrate and more readily degrade after being used and discarded. Processes and apparatus are provided for producing such cigarette filters.
