CELLULOSEFILM AND METHOD FOR PRODUCING THE SAME

摘要

PURPOSE: A cellulose film and a manufacturing method thereof are provided to control elution or breathe out of ultraviolet-absorbing agent, and to have less concern of discoloration. CONSTITUTION: The manufacturing method of the cellulose film(10) is as follows. The first casting undiluted solution includes solvent and the ultraviolet-absorbing agent dissolving the cellulose component, and the cellulose component. The first, second and third casting undiluted solutions are co-extruded to the surface of the belt and are spread in sheet form. The casting undiluted solution evaporates solvent. The cellulose film exfoliates from the belt(30). The exfoliated cellulose film is orientated and desiccated.
