PROBLEM TO BE SOLVED: To prevent the drop resistance of a container from losing due to the lowering of the bond strength of a laminated part with time by a method wherein a polyolefin-based resin layer is directly laminated to the surface of a biaxially oriented plastic film through a water repellent bondability-modified layer, which is provided on the surface of the plastic film. SOLUTION: A laminate 1 is formed by laminating a polyolefin-based resin layer 5 through a ater repellent bondability-modified layer 4 onto the biaxially oriented plastic film 3 surface side of a base material 2 as a support, on at least one side of which the biaxially oriented plastic film 3 is arranged. The surface modification of the biaxially oriented plastic film 3 of the base material 2 is executed by means of a low temperature plasma treating method, in which carbon tetrafluoride or ethylene gas is employed as a treating gas. Thus, the bond strength between the biaxially oriented plastic film and the polyolefin-based resin layer is maintained under the state that a liquid drink such as mineral water or the like is filled and stored in a container made of this laminate. |
