Zusammenfassung:	PROBLEM TO BE SOLVED: To attain excellent processability when canned via a drawing and wiping step, to prevent contents from oxidation and rot and to maintain flavor of contents for a long period of time by incorporating a polymeric oxygen- absorbing agent into a film comprising a polyester mainly constituted of dicarboxylic components and glycol components. SOLUTION: A polymeric oxygen absorbing agent is preferably a polybutadiene diol which is a polymer having a double bond in its molecule. As a catalyst for oxygen absorption is suitably employed a transition metal, and concretely at least one selected among Co, Fe, Ni, Mn and Cu. Besides, an ultraviolet sensitizer, suitably at least one selected from benzophenone and derivatives thereof, is preferably compounded. Further, porous inorganic particles such as silica, alumina, zeolite and the like are incorporated. On at least one surface may be laminated a resin which has no oxygen-absorbing properties.
