<p>[PROBLEMS] To provide a laminated packaging material having a simplified lamination structure for a packaging material having the gas blocking capability, enhancing an inter-layer mechanical strength between a barrier layer and an adjoining layer, and capable of preserving the sealing strength of a sealant layer which is the innermost layer. [Solution] The laminated packaging material has an outer layer made from thermoplastic resin, a paper-made base layer, an EVOH gas barrier layer, and a sealant layer, in which the layer adjoining the gas barrier layer is made from a blend polymer in which 92 to 98 weight % of linear low density polyethylene and 2 to 8 weight % of thermoplastic elastomer are blended, and the thermoplastic elastomer has the affinity with a hydroxyl group and/or a polarized group in the EVOH layer.</p> |
