Resin composition, film, bag product and production process of resin composition

摘要

An object of the present invention is to provide a resin composition improved in film formability and/or mechanical property, particularly tensile elastic modulus or tearing strength, of the film. The present invention provides a resin composition including at least (A) an aliphatic polyester-based resin and (C) a starch, the aliphatic polyester-based resin (A) forming a matrix phase and the starch (C) forming a dispersed phase, wherein the average particle diameter of the dispersed phase is 1 μm or less.

主权项

1. A process for producing a resin composition comprising (A) an aliphatic polyester-comprising resin, (B) a thermoplastic resin other than an aliphatic polyester-comprising resin, (C) starch, and (D) a plasticizer suitable for plasticizing starch, the process comprising:
mixing (X) a composition comprising (B) the thermoplastic resin other than an aliphatic polyester-comprising resin, (C) starch having an average particle diameter of 1 micron or less, and (D) the plasticizer suitable for plasticizing starch, with (A) the aliphatic polyester-comprising resin.
