Polyethylene (PE) and Polyvinyl Chloride (PVC) are two common types of agricultural plastic films with distinct properties. Polyethylene films are generally lighter, more flexible, and less expensive. They are widely used for mulching due to their ability to retain moisture and regulate soil temperature. PE films are also easier to handle and dispose of, making them more environmentally friendly in terms of recycling. On the other hand, PVC films are heavier and more durable, offering better resistance to tearing and punctures. They are often used for longer-term applications such as greenhouses and tunnel films. PVC films can also provide better light transmission and insulation properties. However, PVC is less flexible and more challenging to recycle, which can lead to environmental concerns.
