CELLULOSE FIBER SUSPENSION AND MANUFACTURING METHOD THEREFOR, AND FILM-LIKE FORMED BODY AND MANUFACTURING METHOD THEREFOR

摘要

The present invention provides the suspension of cellulose fibers suitable for producing an oxygen gas barrier film. The present invention provides a suspension of cellulose fibers containing cellulose fibers, a polyvalent metal and a volatile base, wherein the cellulose fibers have an average fiber diameter of not more than 200 nm and the content of carboxyl groups of cellulose composing the cellulose fibers of 0.1 to 2 mmol/g. The suspension is a good material for a film having oxygen gas barrier properties. The present invention provides a film containing cellulose fibers and an inorganic or organic metal salt, wherein the cellulose fibers have an average fiber diameter of not more than 200 nm and the content of carboxyl groups of cellulose composing the cellulose fibers of 0.1 to 2 mmol/g.
