ABSTRACT:
Disclosed is a laminated resin sheet consisting of (a) at least one layer of an ethylene-vinyl alcohol copolymeric resin (EVOH resin), (b) at least one layer of a hot-melt adhesive resin and (c) at least one layer of a polystyrene-based resin, the layer (b) being interposed between the layers (a) and (c) to serve to adhesively bond them together. The laminated sheet has excellent moldability only when the EVOH resin has a thermal characteristic specified in terms of the integrated value of the peak areas in a diagram obtained by the DSC (differential scanning calorimetry) measurement in the course of temperature elevation.
