Agricultural plastic mulch films are used to cover the soil to improve crop growth, reduce weeds, and retain moisture. The different types available on the market include: Clear films for general use, black films to suppress weeds and soil temperature, colored films to deter pests or promote certain crops, biodegradable films that break down over time, perforated films for better aeration, and double-layer films for enhanced insulation. Each type serves specific purposes and is chosen based on the crop, climate, and farming practices.
