Patent ID: 7034077

Claim:
A foil or molded body comprising a transparent and high frequency weldable polymer mixture of: a) at least one polymer selected from a copolymer of ethylene with about 8 to about 60% by weight of comonomers selected from vinyl esters of saturated C 2 –C 8 carboxylic acids, C 1 –C 12 alkylacrylates and methacrylates and having a melt index MFI (190° C.; 2.16 kg) of about 0.2 to about 15.0 g/10 min and b) a copolymer of ethylene with about 10 to about 30% by weight of C 3 –C 12 -α-olefin with a melt index MFI (190° C.; 2.16 kg) of about 0.2 to 15.0 g/10 min, wherein said polymer mixture has a gel content of between about 5 and about 45%, the weight ratio of components a) to b) is between about 95:5 and about 60:40, and the materials of the foil or molded body are partially crosslinked.
