Zusammenfassung:Film or shaped product comprises a transparent and high- frequency weldable polymer blend which is a partially crosslinked mixture of (a) a copolymer of ethylene with comonomers selected from vinyl alkanoates, alkyl (meth)acrylates and optionally carbon monoxide and/or an ethylene or propylene (co)polymer grafted with an unsaturated carboxylic acid, dicarboxylic acid or ester or anhydride thereof, and (b) an ethylene/alpha-olefin copolymer. Film or shaped product comprises a transparent and high-frequency weldable polymer blend which is a partially crosslinked mixture of (a) a copolymer of ethylene with 8-60 wt.% comonomers selected from vinyl esters of C2-C8 saturated carboxylic acids, C1-C12 alkyl (meth)acrylates and optionally carbon monoxide and/or an ethylene or propylene (co)polymer grafted with 8-60 wt.% of an unsaturated carboxylic acid, dicarboxylic acid or ester or anhydride thereof, and (b) an copolymer ethylene with 10-30 wt.% C3- C12 alpha-olefin. Components (a) and (b) both have a melt flow index (190degreesC, 2.16 kg) of 0.2-15 g/10 min.
