Due to the unavailability of traditional film-forming resins, starch is widely used as a raw material for biodegradable mulch films. The heavy consumption of these starch-based mulch films is predicted to contribute considerably to the growth of the biodegradable mulch film sector, as starch is cost-effective and available in significant amounts as compared to other raw materials, such as polylactic acid and polyhydroxyalkanoate.
Besides, benefits including maintenance of soil structure, weed control, and protection of crops from soil contamination, are highly acknowledged by end users. Moreover, farmers are rapidly shifting their focus toward the adoption of starch-based films, because the usage of inorganic mulch films leads to rising environmental concerns.
