<p>Provided is a preparation method for a degradable packaging material; the method comprises using rice hulls, corn bones and recycled plastics as base materials, and then manufacturing the finished product by the steps of providing materials, grinding, mixing and sterilizing, kneading, granulating, extrusion moulding, and plastic-suction and forming, etc. The degradable packaging material prepared by this method has many advantages, such as low cost, full use of resources, and being environmentally friendly. In addition, during the preparation process, chemical changes will occur, so that a highly mixed microstructure is formed in the finished product, which gives the finished product a relatively good mechanical strength, flexibility and thermal resistance properties.</p> |
