PROBLEM TO BE SOLVED: To provide a vinylidene chloride copolymer composition showing an excellent moldability which yields a film showing an excellent barrier property, high-frequency sealing property and retort suitability. SOLUTION: In the vinylidene chloride copolymer composition and its film, when the vinylidene chloride copolymer composition is fractionated by solvent fractionation into three fractions, i.e., fractions A, B and C, fractions A and C have specific ranges of vinylidene chloride resin constitution and specific ranges of weight average molecular weight. |
