Light Transmission: LDPE can allow up to 90% of the light transmission required for photosynthesis, while HDPE has slightly reduced levels but still has good enough transparency for proper plant development.
Flexibility and Strength: Polyethylene's elastic property allows it to endure different climatic challenges without cracking or becoming brittle, thus suiting various environments. Its typical tensile strengths range between 3,000 and 4,000 psi, making it very durable.
UV Resistance: Polyethylene can be improved with UV stabilizers so it does not break down when sunlight exposes it. These treatments often extend the life span even beyond five years under normal conditions.
Thermal Performance: Polyethylene possesses great thermal characteristics, with an insulation value (R-value) around 1.0. Hence, it regulates indoor temperature, largely lowering heating charges, especially during winter seasons.
Cost-effectiveness: Polyethylenes are generally less costly than glass or polycarbonate panels and thus can be used as a large percentage of the greenhouse's structure.
Water Resistance: Polyethylene is inherently resistant to moisture penetration hence it aids in controlling greenhouse humidity levels that would otherwise lead to crop infections caused by excess water.
