These include polyethylene (PE), which is more flexible and durable, and biodegradable plastics like polylactic acid (PLA) and polyhydroxyalkanoates (PHA). Additionally, recycled plastics can be used to reduce environmental impact. Each alternative has its own advantages and limitations, such as cost, durability, and environmental footprint, which must be considered for specific agricultural applications.
