Document Type and Number:
Japanese Patent JP3884456
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for using an agricultural film of an aliphatic polyester based biodegradable resin wherein the film portion exposed on the land surface is free from abnormal rapid deterioration even when used in farm lands under sunlight where a halogen pesticide is sprayed.
