ABSTRACT:
A composite vinylidene chloride copolymer composition excellent in processability which comprises a vinylidene chloride copolymer A having a molecular weight of not less than 50,000 and not more than 300,000 and a vinylidene chloride copolymer B having a molecular weight of not less than 5,000 and not more than the smaller one of either 0.8 times the weight average molecular weight of the vinylidene chloride copolymer A or 80,000, and a monolayer film which comprises the composite vinylidene chloride copolymer composition and is excellent in various properties including barrier property, non-extractability by oily foods and high frequency sealability, and is suitable as a barrier packaging material and wrapping film used for ham, sausage and other like foods.
