Cellulose fiber dispersion polyethylene resin composite material, molded product and pellet using the same, method for producing the same, and recycling method of polyethylene thin film adhered to cellulose fiber

摘要

Cellulose fibers are dispersed in a polyethylene resin, the ratio of the cellulose fibers is 1 part by mass or more and 70 parts by mass or less, and the water absorption rate is the following formula, in a total content of 100 parts by mass of the polyethylene resin and the cellulose fibers. A cellulose fiber-dispersed polyethylene resin composite satisfying the above conditions, a molded product and a pellet using the same, a method for producing the same, and a method for recycling a cellulose fiber-adhered polyethylene thin film piece. [Formula] (Water absorption rate) <(Cellulose effective mass ratio) 2 x 0.01
