MULCHING FILM OF BIODEGRADABLE RESIN FOR PADDY FIELD AND RICE PLANTING USING THE SAME MULCHING FILM

摘要

PROBLEM TO BE SOLVED: To obtain the subject mulching film capable of retaining film shape for a long period after finishing rice planting, preventing occurrence of weeds and remarkably reducing mulching operation by forming the film of a resin component containing a specific polyesteramide-based resin as a main component.;SOLUTION: This mulching film is formed of a resin component comprising a polyesteramide-based resin containing an aliphatic ester structure and an aliphatic amide structure as a main component. At this time, it is preferable that the resin component comprises 50-100 pts.wt. of the polyesteramide-based resin and 0-50 pts.wt. aliphatic polyester resin and inorganic filler and/or a coloring agent is compounded as an additive with the resin component.;COPYRIGHT: (C)2001,JPO
