Abstract
Structures of the present invention contain a non-oriented multilayer film with a polyolefin core having 40 weight-percent or less homogeneous ethylene/alpha-olefin, a modified polyolefin tie layer on each side of the core, and an adhesive layer on at least one tie layer. The adhesive layer contains a polar-modified polyolefin and a polyester, copolyester, or polyester/copolyester blend. The multilayer film has utility as a protective coating for metal surfaces.
