Composite container having barrier property

A lamination product having a barrier property and comprising a packaging material, the packaging material comprising:

• a base material layer comprising at least a polyolefin resin layer constituting an outermost layer and a paper support;
• and three layers directly bonded in sequential order of
• a barrier layer essentially consisting of polyamide resin represented by the following chemical formula;
• an adhesive layer and
• a polyolefin in resin layer constituting an innermost layer, said three layers being arranged in this order on an inner surface side of the base material layer, wherein said three layers are laminated, at the same time respectively, on an exposed surface of the paper support through a coextrusion of fused resin of the respective three layers.

A composite container having a barrier property and comprising a packaging material,

• the packaging material comprising:
• a base material layer comprising at least a polyolefin in resin layer constituting an outermost layer and a paper support;
• and
• five layers directly bonded in sequential order of
• a second polyolefin in resin layer,
• a second adhesive layer,
• a barrier layer essentially consisting of polyamide resin represented by the following chemical formula;
• a first adhesive layer and
• a first polyolefin in resin layer constituting an innermos layer, said five layers being arranged in this order on an inner surface side of the base material layer, wherein said five layers are laminated, at the same time respectively, on an exposed surface of the paper support through a coextrusion of fused resin of the respective five layers, and wherein said barrier layer is formed by coextrusion lamination at an extruding resin temperature of 260-300° C.
