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, and in a total content of 100 parts by mass of the polyethylene resin and the cellulose fibers, the ratio of the cellulose fibers is 1 part by mass or more and 70 parts by mass or less, and the polyethylene resin is In the molecular weight pattern obtained by gel permeation chromatography measurement, a cellulose fiber-dispersed polyethylene resin composite material satisfying the relationship of 1.7>Full width at half maximum (Log(MH/ML))>1.0 was used. Molded bodies and pellets, methods for producing these, and methods for recycling cellulose fiber-adhered polyethylene thin film pieces.
