A laminated article comprises a substrate having opposite major surfaces, and a multi-layer lamination composition comprising (i) a base layer and (ii) an adhesion layer bonded to at least one surface of the base layer. The adhesion layer (ii) comprises a propylene copolymer which comprises units derived from propylene and from about 3 to about 25 wt % of units derived from ethylene and/or a Cto Calpha-olefin and which has a melting temperature less than about 105&#xb0; C. and a heat of fusion less than about 75 J/g. The lamination composition is thermally laminated to the substrate such that said adhesion layer (ii) is bonded to at least one major surface of said substrate.

Laminated articles and their production

A polymeric composition that is suitable for use as a film or a coating. The polymeric composition comprises: (a) a first component comprising copolymer derived from ethylene and one or more Cto C&#x3b1;-olefin comonomers. The first component has a density of about 0.911 to about 0.918 g/cm, a compositional distribution breadth index (CDBI) of about 60% to about 85%, a melt index (MI) of about 16.0 to about 30.0 g/10 min, a molecular weight distribution (MWD) of about 1.5 to about 4.0, and a melt index ratio (MIR) of less than about 25; and (b) a second component comprising a low density polyethylene (LDPE). The second component has a g' of about 0.8 to about 0.15 and a MI that is lower than the MI of the first component.
