ABSTRACT:
A laminar article comprising a blend of at least one olefin polymer and at least one ethylene-vinyl alcohol copolymer. If desired, a compatibilizer may also be included in the blend. The melting point of the ethylene-vinyl alcohol copolymer having the highest melting point in the blend is at least 5.degree. C. below the melting point of the olefin polymer having the lowest melting point in the blend. The melt index of the olefin polymer can be higher than, lower than, or equal to the melt index of the ethylene-vinyl alcohol copolymer.
