Disclosed is a multilayer sheet which has excellent flexibility, transparency, impact resistance, heat resistance, heat-sealing properties and cleanliness, rarely undergoes deterioration in appearance, fluctuations in thickness or the like during multilayer molding, has good moldability, and is rarely reduced in the strength of a sheet base material even when the thickness of the sheet is reduced. Also disclosed is a packaging material for a heating treatment. Specifically disclosed is a multilayer propylene resin sheet comprising at least two layers, i.e., an inner layer (1) and an outer layer (2), wherein the inner layer (1) comprises a resin composition (X) which comprises 60 to 90 wt% of a propylene resin composition (A) comprising 30 to 70 wt% of a specific propylene-a-olefin random copolymer component (A1) and 70 to 30 wt% of a propylene-ethylene random copolymer component (A2), 40 to 10 wt% of an ethylene-a-olefin copolymer (B), and 1 to 25 wt% of a propylene resin (C)and wherein the outer layer (2) comprises a specific propylene resin composition (Y). Also specifically disclosed is a packaging bag for a heating treatment, which comprises the multilayer propylene resin sheet. |
