<p>The laminate which is resistant to delamination, comprises in alternate arrangement barrier layers and adhesive layers. The barrier layer is prepd. from purified (co)polymer of vinyl alcohol and the adhesive layer is prepd. from modified polyolefin in which polyolefin (co)polymer is blended with another copolymer of polyethylene grafted with unsatd. polycarboxylic acid b hydride. The barrier layer is a copolymer layer of ethylene-vinyl alcohol or a homopolymer of polyvinyl alcohol. The plastic film is not oxygen permeable and is used for producing a filmy container for foods and oxidative deterioration.</p> |
