摘要

The present invention relates to a laminate which has oxygen barrier property and flavor barrier property and which is excellent in sealing property and anti-delamination property, and to a paper container and a package utilizing the laminate and suitable for long term storage of contents and excellent in disposability. The laminate is characterized in that the same comprises a multi resin layer including at least three layers comprising adhesive resin layer (a)/barrier resin layer (b)/adhesive resin layer (a') coextrusion laminated onto a base paper coated with polyethylene imine such that the adhesive resin layer (a) is contacted with the coated surface of the base paper, thereby enhancing an adhesion strength between the coextrusion laminated resin layer and the base paper, with lower odor and excellent barrier property.
