摘要: The invention relates to a process for producing a polypropylene film having a small dynamic coefficient of friction (CoF) and to a film obtained by this process. The invention further relates to the use of a polypropylene composition in a film forming process in order to reduce the required amount of slip agent for achieving a certain CoF and, alternatively, to the use of a polypropylene composition in a film forming process in order to reduce the required storage time for achieving a certain CoF.
