Patent

CA 2438755

The invention relates to a foil or moulded body used on a transparent and high frequency weldable polymer mixture containing a) (I) a copolymer of ethylene with about 8 to 60 % by weight of comonomers, selected from vinyl esters of saturated C2-C8 carboxylic acids saturated C1-C12 alkylacrylates and methacrylates, optionally with carbon monoxide as termonomer, and/or (II) ethylene homopolymer, ethylene copolymer, propylene homopolymer and/or propylene copolymer with about 8 to 60 % by weight of grafted units of unsaturated carboxylic acids, dicarboxylic acids, their esters and/or anhydrides or (III) a mixture of two or more of the above mentioned compounds, independently of their allocation to groups, whereby the polymers or their mixture have a melt index MFI (190°C; 2.16 kg) of about 0.2 to 15.0 g/10 min and b) a copolymer of ethylene with about 10 to 30 % by weight of C3-C12- .alpha.-olefin with a melt index MFI (190°C, 2.16kg) of about 0.2 t o 15.0 g/10min, whereby the material of the foil and of the moulded body is partially interlaced.
