Multilayered film comprising a sealing layer chosen from ethylene-methacrylic acid copolymers (EMAA) with a content of methacrylic acid from 4 to 18% by weight, ethylene-acrylic acid copolymers (EAA) with a content of acrylic acid from 4 to 15% by weight, and a mixture of 50 -99% of at least one of said EMAA and EAA copolymers with 50-1% by weight of at least another ethylene polymer or copolymer. The film has improved sealing properties and strength of the seal. |
