Photometric Analysis of Low-Density Polyethylene for Enhanced Greenhouse Films

Low-density polyethylene (LDPE) has emerged as a versatile material for greenhouse coverings, offering sustainable solutions to enhance agricultural productivity. Light transmission and diffuse reflection are crucial considerations when selecting greenhouse covering materials. High light transmission is desirable to facilitate photosynthesis and healthy plant growth by allowing ample sunlight to reach plants. Conversely, diffuse reflection scatters light evenly, reduces shadow formation, and ensures uniform light distribution across plants, promoting optimal growth. Certain greenhouse coverings are engineered to possess specific levels of diffuse reflection, further enhancing plant growth and yield. This paper investigates the role of LDPE in optimizing environmental conditions and improving crop performance in greenhouse systems. It emphasizes the potential of LDPE as a sustainable solution for maximizing crop production by measuring its optical properties as diffuse reflection and the ultraviolet protection factor (UPF). Where excessive exposure to UV radiation can lead to sunburn, reduced photosynthesis, and damage to plant tissues.
