<p>PROBLEM TO BE SOLVED: To provide a composition for calendering containing a polypropylene resin and paper, etc., to be recycled, having excellent calendering formability, free from the winding trouble on the roll in calendering, easily producing a calendered product having good appearance and enabling the effective utilization of resources such as paper. SOLUTION: The calendering composition contains 10-49 wt.% polyolefin resin composition for calendering containing 80-95 wt.% ethylene/propylene random copolymer having an MFR of 0.1-3 g/10 min, an ethylene content of 2-4.8 wt.% and a molecular weight distribution (Mw/Mn) of 4-7 and 5-20 wt.% ethylene/α-olefin random copolymer composed of ethylene and a 4-10Cα-olefin and having an MFR of 0.5-5 g/10 min and a density of 0.860-0.895 g/cm<3> and 51-90 wt.% molding component selected from paper, corn starch, bamboo powder and charcoal powder.</p> |
