Preparation method and application of biodegradable agricultural crop fiber environmental protection packaging material

A crop fiber pulp containing major components such as crop fiber, starch binders, and functional additives, wherein the crop fiber is obtained by non-chemical treatment, and the treatment methods include mechanical pressing and oil removal, supersaturated steam cooking and softening, and sudden The decompression explosion, cutting and fine grinding are performed; in the invention, the starch adhesive can be a carrier type, a carrierless type, a carrier-free carrier type starch glue, is alkaline, has a stable viscosity, is biodegradable, and has self-retained, Residue and water resistance.

Environmental protection and biodegradability are among the most important factors in considering the commercial value of packaging materials today. The present invention relates to a method of using non-chemically treated crop fiber, and a method of formulating a starch binder. The present invention also relates to a method for producing environmentally friendly, biodegradable packaging products using non-chemical methods to produce crop fiber, in conjunction with starch binders. The agricultural crop fiber of the invention is cooked by high-temperature superheated steam, and is decompressed and exploded. The processed crop fiber is blended with the metered starch binder, and after proper mixing, the ideal crop fiber slurry is prepared as a feed for the production of environmentally friendly packaging products. The agricultural fiber pulp of the present invention is suitable for the production of packaging materials for crop fiber molded packaging products and crop fiberboard boards and the like. The starch binder in the present invention is made from natural raw materials, is biodegradable, and has the functions of self-retention and retention.
