Technical Field
[0001] The utility model relates to the technical field of biodegradable films, in particular to a biodegradable film capable of dispersing external impact force. Background Art
[0002] Biodegradable mulch refers to a type of plastic mulch that can be degraded by microorganisms in natural environments. When microorganisms such as bacteria, fungi, and actinomycetes invade the plastic film, their cell growth causes the polymer components to hydrolyze, ionize, or protonate, leading to mechanical damage and fragmentation into oligomeric fragments. Enzymes secreted by the fungi or bacteria decompose or oxidize the water-soluble polymers into water-soluble fragments, generating new small-molecule compounds until they ultimately decompose into CO2 and H2O.
[0003] Existing biodegradable films do not have dust and insect-proof functions when in use, and cannot disperse external impact forces, resulting in a lack of buffering and protective effects. In addition, existing biodegradable films have poor thermal insulation, moisture-proof and wear-resistant properties, making the contact surface between the biodegradable film and the soil easily worn out. Therefore, there is an urgent need for a biodegradable film that can disperse external impact forces to solve the above technical problems. Utility Model Content
