BIODEGRADABLE AGRICULTURAL MULCH FILM

摘要

PROBLEM TO BE SOLVED: To obtain an agricultural mulch film that has high water vapor permeability as a biodegradable agricultural mulch film, is produced by an ordinary film processing machine and especially has improved water vapor barrier properties. SOLUTION: The agricultural mulch film comprises at least 20 parts wt. of an aromatic/aliphatic polyester-based resin based on 100 parts wt. of a biodegradable polyester resin component and 10-50 parts wt. of an inorganic filler and has≥2.0 blow ratio formed by a tubular film process. The agricultural mulch film comprises≤80 parts wt. of an aliphatic polyester-based resin except the aromatic/aliphatic polyester-based resin. COPYRIGHT: (C)2005,JPO&NCIPI
