Biodegradable mulch film is a type of agricultural plastic film used to cover soil and protect crops from weeds, insects, and other environmental factors. Unlike traditional plastic mulch films, biodegradable mulch film is made from biodegradable materials that can break down naturally in the soil, reducing the environmental impact of agricultural practices.The biodegradable materials used to make mulch film can include plant-based polymers, such as polylactic acid (PLA), or synthetic materials that have been modified to be biodegradable. The film is designed to break down over time, allowing it to be tilled into the soil or left in place to decompose naturally.
