Patent ID: 7790281

Claim:
A film for surface protection comprising: at least one base layer comprising a low density polyethylene or an interpolymer of ethylene and an alpha olefin having form 3 to 12 carbon atoms, a heat of fusion of at least 80 J/g, and a density of from 0.915 to 0.94 g/cm 3 ; and a surface layer for removably adhering to a substrate wherein the surface layer comprises: at least 40 wt % of an elastomeric propylene-based polymer comprising ≧50 wt % propylene and 5-30 wt % ethylene derived units, having a hest of fusion derived from isotactic propylene type crystallinity as determined by DSC of less than 40 J/g; an ethylene-based polymer in the form of an ethylene-alpha-olefin copolymer having from 3 to 12 carbon atoms and a heat of fusion of less than 75 J/g and a density of less than 0.91 g/cm 3 ; an ethylene-vinyl ester copolymer having from 5 to 60 wt % of the ester derived units; and less than 40 wt % of a propylene based polymer having a heat of fusion of greater than 70 J/g; wherein the film has a thickness of from 25 to 100 μm and a T-peel strength of from 0.5 to 5 N/25 mm; and wherein the substrate is selected from the group consisting of glass, stainless steel (SS), polyurethane (PU), polycarbonate (PC), polymethylmethacrylate (PMMA), polyvinyl chloride (PVC), aluminum (Al), polyester (PET), and polyvinylidene fluoride (PVDF).
