ABSTRACT:
Films containing a sealant layer composition comprising:(1) polyethylene homopolymer, and ethylene/alpha-olefin copolymer, ethylene vinyl acetate copolymer, and ethylene/acrylate copolymer; and(2) elastomer, plastomer, ionomer, and carboxyl-modified polyethylene;when sealed to another outer film layer comprising at least one member selected from the group consisting of ionomer, ethylene/acid copolymer, ethylene/vinyl acetate copolymer and ethylene/acrylate copolymer, have been discovered to provide a seal strength comparable to an ionomer to ionomer seal.
