In order to enhance the mechanical properties of the chitosan film, a waste paper cellulose/chitosan film was prepared. Using discarded corrugated paper as raw material, regenerated cellulose was obtained through alkali treatment and bleaching treatment, and then different components and chitosan were used to prepare films. Morphological observation and mechanical properties of different raw material films were carried out. The results showed that the cellulose was filamentous with a fiber diameter of 15~20 μm, and its crystallinity was much higher than that of original corrugated paper. When the relative mass fraction of waste paper cellulose of 5% was added into 2% chitosan solution, the mechanical properties of cellulose/chitosan film were the best, the maximum tensile strength reached 52.3 MPa, the elongation at break was more than 20%, with the cellulose evenly distributed within.
