An olefinic resin composition having the specific range of density, melt flow rate (MFR), viscoelastic properties and melt tension is obtained. The composition comprises (A) a polyethylene, (B) an ethylene/.alpha.-olefin copolymer having the MFR of 0.1 to 10, and (C) an ethylene/.alpha.-olefin copolymer or a propylene/.alpha.-olefin copolymer having the MFR of 20 to 200. When the composition is processed by calendering, its feed to the rolls and take-up from the rolls are satisfactory, and high-speed formation of sheets having high accuracy in thickness is possible. The compounding of a fire retardant and a foaming agent to the composition enables fire-retardant foamed sheets being bulky and giving a good feel to be obtained. The lamination of these sheets onto the paper substrate is suitable for wall paper.
