AGRICULTURAL MULTILAYER FILM

摘要

PROBLEM TO BE SOLVED: To obtain an agricultural multilayer film causing neither reduction of ultraviolet absorption power nor decrease of long-term weather-resistant performances due to bleedout. SOLUTION: This agricultural multilayer film is obtained by a method that when an ultraviolet light absorber is added to an agricultural multilayer film, the content X of the ultraviolet light absorber in the middle layer is higher than the content Y of the ultraviolet light absorber in the inner layer and the content X is higher than the content Z of the ultraviolet light absorber in the outer layer.
