    摘要: A film having a dynamic modulus of elasticity at 75.degree. C. of 10.sup.8 to 10.sup.11 dyne/cm.sup.2 and an oxygen permeability at 20.degree. C., 75% RH of not more than 5.times.10.sup.12 cc.cm/cm.sup.2.sec.cmHg comprises a polyalcohol obtained by reducing a polyketone comprising a carbon monoxide-ethylene alternate copolymer, the polyalcohol having an intrinsic viscosity of 0.3 to 3.0 dl/g and a melting point of 110.degree. to 180.degree. C.; and a laminated film comprising the same. These films have excellent high-speed bag formability, heat-pack sealability, film formability, film appearance, adhesiveness and gas barrier properties.
