Zusammenfassung:3 The invention relates to a film for surface protection having at least one base layer and a surface layer for removably adhering to a substrate comprising at least 40 wt % of an elastomeric propylene-based polymer with a heat of fusion derived from isotactic propylene type crystallinity as determined by DSC of less than 40 J/g and optionally an ethylene-based polymer in the form of an ethylene-alpha-olefin copolymer having a density of less than 0.91 g/cmand/or an ethylene-vinyl ester copolymer having from 5 to 60 wt % of the ester derived units and/or optionally less than 40 wt % of a propylene based polymer having a heat of fusion of greater than 70 J/g. The films have good initial tack.
