Degradable starch-based foam molding packaging material manufacturing method and product thereof

A method for manufacturing a degradable starch-based foam molding packaging material comprises the following steps: a. 80 to 92% by weight of starch and 8 to 20% by weight of additives are mixed, mixed at a high speed, and fed into an extruder; The medium heats the foaming, extrudes and spins into the spherical starch foam particle material through the porous discharging template, wherein the sum of the weight percentages of the starch and the additive shall be 100%; b. spraying the hot melt adhesive to the spherical starch foam particle material. After cooling at room temperature, the cavity of the forming mold is filled and the mold is filled with hot dry air. After the pressure is applied, the mold is cooled and demoulded.

Foam, extrusion spin-cut into spherical starch foam particles; b. Spray hot melt adhesive to the spherical starch foam particles, fill the mold cavity of the molding mold after cooling at room temperature, and mold the mold to inject hot dry air, add pressure to make Mold cooling is the finished product. The product has the advantages of low density, high elasticity, high compressive strength, good waterproof performance, low cost, excellent environmental degradation after being discarded, and can be continuously industrialized. It is an ideal choice for replacing the existing foam plastic packaging materials such as EPS styrofoam.
