The multilayered film has a base layer (A) and at least one surface layer (B). The film-forming component of base layer (A) is at least one copolymer of A1) ethylene and A2) an ethylenically unsaturated carboxylic acid or an ionomer thereof. The film- forming component of base layer (B) is an ethylene homopolymer or a copolymer of ethylene and at least one alpha-olefin having from 3 to 12 carbon atoms, or a blend of said polymers. The weight of the base layer (A) is from 25 to 75 percent by the total weight of (A) and (B). The multilayered film is useful for wrapping food. |
