| titleOfInvention | Disposable lunch box based on degradable composite packaging material |
| abstract | The invention provides a disposable lunch box based on a degradable composite packaging material, which belongs to the technical field of degradable materials and comprises the steps of forming the degradable composite packaging material by a process selected from the group consisting of extrusion, thermoforming, injection molding, blow molding, rolling, compression molding and transfer molding; the degradable composite packaging material is prepared by mixing and granulating activated straw powder, polylactic acid and an additive which are respectively treated by a strong alkali solution and an ethanol solution containing a silane coupling agent and polymaleic anhydride. The degradable composite packaging material has higher tensile strength, bending strength and impact strength, lower surface viscosity and melting temperature, better processing performance and capability of being completely degraded in natural environment, wherein the natural degradation rate reaches 89% in 30-50 days, and the natural degradation rate reaches 100% in 100-180 days. |
