Abstract
The present invention provides resin compositions comprising a blend of two different saponified products of ethylene-vinyl acetate copolymers. The composition is much improved compared to a single EVOH in flexibility without adversely affecting the transparency and gas barrier property. Laminate films comprising at least one layer of said composition are excellent in resistance to dropping shock, ability to prevent air-back, skin-pack adaptability and shrink-packaging capability.
