BIODEGRADABLE COMPOSITE SHEET, BAG USING IT, AND STORAGE BAG FORMED OF VEGETATION MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a biodegradable compound sheet optimum to manufacture a vegetation material storage bag which can be used for a storage bag in carrying and storing the vegetation material, and form open hole parts through water sprinkling or raining after installed on the ground, easy in vegetation and completely unnecessary for collection after the vegetation is completed, a bag using the sheet, and the vegetation material storage bag. SOLUTION: In a compound sheet, a strip-like lamination part 2 formed of a biodegradable resin and a non-lamination part are alternately provided on a surface of a water-soluble or water-dispersant base material 1. A biodegradable compound sheet in which the lamination part 2 is not less than 50% in area of the base material, or a biodegradable compound sheet in which a part between the strip-like lamination parts 2 is connected by a straight or strip-like lamination part to form a net-like biodegradable lamination part, is used and heat-sealed to form a bag and a vegetation material storage bag joined with the biodegradable resin of the lamination part.
