Abstract: The disclosure generally relates to a looped pile film roll core used for winding a polymeric film, a method of winding film on the looped pile film roll core, and a roll of film that includes the looped pile film roll core. The disclosure describes an article and a process to reduce the core impressions created by the starting end of a web on the adjacent web layers next to the core. In one particular embodiment, the present disclosure can lead to a reduction in the amount and severity of such core impressions on a wound polymeric film, by reducing the amount of stress in adjacent layers of wound web.
