An ethylenic copolymer composition including an ethylenic copolymer having Mw/Mn of 1.5 to 4, Mw of 3,000 to 1,000,000, and a resin density of 0.85 to 0.95 g/cm<3>. The relationship between the half width at the half maximum [W/2] of the Gaussian distribution curve, and the average, n, of short-chain branches in the copolymer satisfies the equation,The ethylenic copolymer composition also includes an ethylenic copolymer having an Mw of 3,000 to 1,000,000 and a resin density of 0.85 to 0.95 g/cm<3>.
