Greenhouse plastic covers are rapidly evolving, with new materials and technologies offering tailored solutions for both farmers and the local environment. Some of the most prominent materials used in greenhouse plastic covers include:
- Polyethylene (PE): Widely used in agricultural settings, PE films are an affordable and versatile covering option known for their excellent light transmission, low permeability to air and water, and ease of customisation. However, as PE films can degrade and lose their properties due to UV exposure, it is essential to choose a cover with adequate UV protection when using PE-based materials.
- Polycarbonate (PC): Offering a disruptive innovation in the world of greenhouse plastic covers, polycarbonate sheets provide exceptional rigidity and insulation, withstanding hail, snow, and extreme wind conditions. PC covers possess a high light transmission capability while dispersing light effectively, resulting in reduced shading and more uniform plant growth.
- Ethylene-vinyl acetate (EVA): EVA films are emerging as an alternative to traditional PE films, offering enhanced durability and UV protection. Combining the benefits of PE and PVC, EVA films serve as an excellent middle ground for greenhouses requiring a more robust but flexible covering material.
