Abstract:
The invention relates to a honeycomb film made of a biodegradable polymer which has biodegradation properties as an anti-adhesion membrane for preventing adhesion after an operation, is excellent in handling properties, and exhibits a satisfactory adhesion preventive effect stably over a desired period of time, and to a production process of the same. Above all, the invention provides an anti-adhesion membrane of a honeycomb film made of polylactic acid as a biodegradable polymer and a phospholipid and a production process of the same.
