The present invention relates to a plant cellulose film composed of by weight 50-90% of plant cellulose, 0.2-40% of modifier and 5-20% of water. The plant cellulose film may contain herbicides, insecticides, germicides, fertilizing nutriments of N, P and K, trace elements and rare-earth elements. The plant cellulose film may be used as decomposable farming film and packaging material for goods, food such as sausages, fruits, vegetables, candies and cakes, pharmaceuticals and garbage, and carpets for man-made lawn. The plant cellulose and hemi-cellulose may also be used to make disposable cups, dishes, and food boxes. The method of preparing the plant cellulose film comprises the following process steps: concentrating, pressing, shredding, degrading xanthating and dissolving, filtering, ripening into viscose, spinning, coagulating, regenerating, desulphurizing, bleaching, plasticizing, pressing, drying, coating and winding into films. |
