<p>A film having a dynamic modulus of elasticity at 75 DEG C of 10<8> to 10<11> dyne/cm<2> and an oxygen permeability at 20 DEG C, 75% RH of not more than 5 x 10<-12> cc.cm/cm<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 to 180 DEG 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.</p> |
