Cellulose-based polymer packaging method, cellulose-based polymer transportation method, and cellulose-based polymer packaging material

The present invention addresses the problem of providing a packaging method suitable for transportation or the like of a cellulose-based polymer, and also addresses the problem of providing a packaging method suitable for transportation while suppressing a decrease in the viscosity of the cellulose-based polymer. The cellulose polymer is packaged so as to satisfy the following conditions (1), (2), and (3). Condition (1): The inside of the packaging bag having gas barrier properties is filled with a cellulose polymer. Condition (2): The oxygen concentration in the packaging bag is adjusted to 0.8% or less and the packaging bag is sealed. Condition (3): when the packaging bag filled with the cellulose-based polymer is arranged in a manner that the longest long side L is horizontal, the depth D of the packaging bag from the horizontal arrangement surface and the long side L satisfy the relational expression: 6.1 < = L/D < = 10. In addition, the surface of the outermost layer of the packaging bag has a static fri
