Laminate containing a polyolefin layer adhered to a base layer. The polyolefin layer contains a blend of 90-99.7 wt % of a copolymer comprising 80-98 wt % of propylene and 2-20 wt % of C2-C10 α-olefin units, and 0.3-10 wt % of a polyethylene having a density of 870-920 kg/m3 or less. The base layer includes a propylene homopolymer or a copolymer of propylene and up to 5 wt % of C2-C10 alpha-olefin units other than propylene.
