发明名称 Polyolefin film, its use, and process for its production
摘要 Multilayer, biaxially oriented polyolefin film with a base layer and at least one outer layer, in which the base layer contains a fatty acid amide and outer layer D1 contains at least 80 wt.% of a linear olefin polymer (LOP). Independent claims are also included for: (a) A process for the production of this film by coextrusion of the melts for the different layers through a sheet die, drawing the film over a takeoff roller at 40-100 degrees C, biaxially stretching with ratios of (4:1)-(7:1) in the machine direction and (8:1)-(10:1) in the transverse direction, heat-fixing, optionally subjecting to corona treatment and then winding on a spool; (b) laminates containing this film and a layer of polyethylene.
