PURPOSE:To obtain the subject composition capable of reducing distillation residues and providing a film suitable for packaging fatty foods by using and blending a polyvinyl chloride-based resin with specific amounts of an aliphatic polybasic acid-based polyester plasticizer having a specified molecular weight and a specific glycerol ester in combination. CONSTITUTION:A composition obtained by blending (A) 100 pts.wt. polyvinyl chloride-based resin with (B) 5-40 pts.wt. aliphatic polybasic acid-based polyester plasticizer [e.g. poly(ethylene glycol/adipic acid) ester] having 1000-3000, preferably 2000-2500 molecular weight and (C) 40-1 pt.wt. glycerol ester expressed by the formula (R1, R2 and R3 are 2C acyl, acyl consisting essentially of 10-14C or H). |
