Title: METHOD FOR PRODUCING BIODEGRADABLE POLYESTER FILM
Abstract:
Provided is a method by which a biodegradable polyester film containing a polyhydroxyalkanoate is able to be stably produced by inflation molding under practical processing conditions. A method for producing a biodegradable polyester film, which contains a biodegradable aliphatic polyester (A) and a fatty acid amide (B), by inflation molding, wherein the biodegradable aliphatic polyester (A) contains a polyhydroxyalkanoate. This method for producing a biodegradable polyester film comprises: a step (I) for dry blending the biodegradable aliphatic polyester (A) with a master batch that contains the fatty acid amide (B) and a base material resin; and a step (II) for subjecting a mixture which is obtained in the step (I) to inflation molding.
