PROBLEM TO BE SOLVED: To provide a polyethylene resin material having the same flexibility and calendering processability as those of a soft polyvinyl chloride resin and not causing the migration of a plasticizer, a smell and pollution on incineration. SOLUTION: This composition for calendering comprises (A) high pressure low density polyethylene having a melt index of 0.2-10 g/10 min, a density of 0.915-0.930 g/cm<3> and the main peak value of the DSC melting point in a range of 104-117 deg.C, (B) an ethylene-α-olefin copolymer having a melt index of 0.2-10 g/10 min, a density of 0.86-0.910 g/cm<3> , a Mw/Mn of <=3.0 and the main peak value of the DSC melting point in a range of 40-105 deg.C and produced in the presence of a polymerization catalyst comprising a metallocene catalyst, and (C) at least one kind of lubricant selected from carboxylate esters and having a melting point of 40-110 deg.C, in an A/B weight ratio of 80/20 to 10/90 and in a C/(A+B) weight ratio of (0.2-3)/100. |
