Mulching film is a thin plastic material laid on the soil surface, commonly used in agriculture and horticulture. Typically made from plastics like polyethylene (PE) or polypropylene (PP), it comes in various thicknesses and colors tailored to specific planting needs. Its primary functions include regulating soil temperature, retaining soil moisture, suppressing weed growth, and shielding crops from pests and diseases. In greenhouse or outdoor cultivation, mulching film protects crop roots from severe cold or arid weather, aiding in increased crop yields and quality.
