<p>PROBLEM TO BE SOLVED: To provide a multilayer extruded body excellent in moldability, trans parency, luster and see-through feeling. SOLUTION: The multilayer extruded body has an inner layer comprising at least one layer constituted mainly of an ethylene/α-olefin copolymer obtained by polymerizing at least one kind ofα-olefin of which the melt flow rate and the density are in prescribed ranges respectively, of which the melt flow rate ratio, the molecular-weight distribution and the activation energy of an apparent flow are in specified ranges respectively and of which the ethylene and the number of carbons are in prescribed ranges respectively, and an outer layer constituted of a low-density polyethylene of which the melt flow rate, the density and the swell ratio are in prescribed ranges respectively and of which the melt flow rate ratio, the molecular-weight distribution and the activation energy of the apparent flow are in specified ranges respectively. The body has a constitution of the outer layer/the inner layer/the outer layer.</p> |
