A method for producing a polymeric material is disclosed. The method combines blending of fibers and treating the fibers with a basic aqueous solution. In some embodiments, the blending of the fibers is performed at a blending speed sufficient to shear the fibers in one or both of a longitudinal direction and lateral direction of the fibers. In some embodiments, one or both of the blending and treating are performed in a sub-zero temperature, at a temperature of less than 0oC, or in a range of from about 0oC to about -20oC. One example application of the method is in the making of a cellulose film from wood pulp.
