Agricultural Reflective PE Film is a specialized functional agricultural covering material developed based on polymer materials science and agricultural environmental regulation technology. This film, which uses polyethylene (PE) resin as the base substrate, constructs a composite structural system with multiple physical barriers and optical regulation functions through the precise proportioning of functional additives (such as nanoscale reflective fillers, anti-aging agents, and anti-fogging agents) and advanced extrusion molding processes. Its core application objectives focus on three key dimensions of agricultural production: systematic optimization of crop growth microenvironments, precise regulation of soil water-heat balance, and efficient conversion and utilization of solar radiation energy.
