PURPOSE:To obtain an inexpensive laminate improved in gas barrier properties and excellent in hot water-resistant blocking properties by applying a molten multilayered material containing a compsn. layer consisting of a saponified ethylene/vinyl ester copolymer and an adhesive resin layer to a base material by co-extrusion coating. CONSTITUTION:A molten multilayered material containing at least two layers of a compsn. layer consisting of 51-98wt.% of a saponified ethylene/vinyl ester copolymer wherein ethylene content is 20-65mol% and the saponification value of a vinyl ester component is 90mol% and 2-49wt.% of polyamide and an adhesive resin layer is applied to a base material by co-extrusion coating. By this method, a product having a polyamide compsn. layer as the outermost layer is obtained. |
