<p>The invention discloses a propylene resin sheet and a heat-treatable packaging material which have an excellent transparency, flexibility and very-low-temperature impact resistance, and which reduce the thickness variation during lamination, suppress appearance defects such as interfacial roughness. A propylene resin sheet composed of at least one layer, the main layer being made up of a resin composition containing: (1) 50 to 90 wt % of a propylene resin composition (A) which includes from 30 to 70 wt % of a propylene-±-olefin random copolymer component (A1) having a melting peak temperature of 120 to 150°C, and from 70 to 30 wt % of a propylene-±-olefin random copolymer component (A2) having a C 2 or C 4-8 ±-olefin content of at least 10 wt % but less than 20 wt %; and (2) 10 to 50 wt % of a specific ethylene-±-olefin copolymer (B).</p> |
