Abstract: A laminate for flexible packaging and a process for preparing the same. The laminate for flexible packaging is obtained by joining a plurality of flexible blanks via layers of an adhesive agent, wherein the layers of said adhesive agent are layers of an isocyanate-terminated polyurethane type hot-melt resin that is crosslinked with the moisture, the residual amount of an organic solvent in said laminate is 10 .mu.g/m.sup.2 or smaller per a unit inner surface, the peeling strength at 25.degree. C. is 250 g/15 mm of width or greater, and a peeling strength retentivity at 80.degree. C. is 30% or greater of the peeling strength at 25.degree. C.
