CELLULOSE-FIBER DISPERSION POLYETHYLENE RESIN COMPOSITE MATERIAL, FORMED BODY AND PELLET USING SAME, PRODUCTION METHOD THEREFOR, AND RECYCLING METHOD FOR CELLULOSE-FIBER ADHESION POLYETHYLENE THIN FILM PIECE

摘要

A cellulose fiber dispersion polyethylene resin composite material formed by dispersing a cellulose fiber into a polyethylene resin, in which a proportion of the above-described cellulose fiber is 1 part by mass or more and 70 parts by mass or less in a total content of 100 parts by mass of the polyethylene resin and the cellulose fiber, and the polyethylene resin satisfies a relationship: 1.7half-width (Log(MH/ML))1.0 in a molecular weight pattern obtained by gel permeation chromatography measurement, and a formed body and a pellet using the same, a production method therefor, and a recycling method for the cellulose fiber adhesion polyethylene thin film piece.
