What are the differences between single-layer and multilayer agricultural plastic films?

Single-layer agricultural plastic films are made from a single type of material and are simpler in structure. They are typically less expensive but may not offer the same level of protection or durability as multilayer films. Multilayer films, on the other hand, are composed of multiple layers of different materials fused together. This construction allows for enhanced properties such as better barrier against water and gases, improved UV resistance, and tailored release of nutrients or chemicals. Multilayer films can also be designed for specific applications, like controlled release of fertilizers or pesticides, making them more efficient for certain agricultural needs.
