The invention is directed to foamed film comprising a polyethylene foam obtained by physically foaming of a low density polyethylene copolymer with a density between 910 kg/m3 and 935 kg/m3 (according to ISO 1183) and a melt index between 0.10 and 100 dg/minute (according to ASTM D1133) wherein the low density polyethylene is obtained by a high pressure polymerization process of ethylene in the presence of a di- or higher functional monomer.
