型ビール剥離した時の最大強度で表わしたものである。The adhesive strength was measured by cutting a test piece with a width of 15 cm and a length of 80 m parallel to the laminating direction of the laminated film.20 cages were peeled in advance between the aluminum vapor-deposited film and the extruded laminate layer, and the residual whiteness was 0°. The peeling speed is 300/min.
It is expressed as the maximum strength when the mold beer is peeled off.
