What are the main differences between traditional plastic mulch film and biodegradable plastic mulch film, and how are manufacturers addressing sustainability?

Traditional plastic mulch films are typically made from polyethylene (PE), which is durable but non-biodegradable. These films help control weeds, retain soil moisture, and regulate soil temperature, but they pose significant disposal challenges. Farmers often need to collect and properly dispose of used film, which adds labor and environmental costs. In contrast, biodegradable plastic mulch films are designed to break down naturally in the soil, eliminating the need for removal. These are made from materials such as PLA (polylactic acid), starch blends, or other bio-based polymers.
