Starch and its derivatives can be used as binders and lubricants, and can be cured under certain conditions. Calcium carbonate is used as a filler to increase strength. Fibers can play a traction role with each other, making them have a pulling effect and are not easy to be hit. Shredded, and finally a protective layer makes the tableware and packaging materials resistant to weak acids, water, oil and heat. The starch, fiber, calcium carbonate, and protein in the technical solution are selected into the blender in an appropriate ratio, and then the water is about 200 times more than the total weight of the above components and ingredients to be fully stirred and mixed to make it puffed. The agitating material is poured into a water-absorbing mold to make it absorbent to form, and then the machine is used for hot pressing or drying to set the shape. Generally, the temperature of the hot-pressing mold is 120-200. C. Finally, after spraying or immersing the previous protective layer, the die-cutting edge is used for hot pressing or cutting edge drying, and finally the finished product is packaged.
