Farmers choose high-quality agricultural plastic products for their fields by considering several factors. They look for durability, ensuring the material can withstand weather conditions and physical stress. UV resistance is crucial to prevent degradation from sunlight. They also consider the product's flexibility to adapt to different field shapes and temperatures. The permeability of the plastic is important for water and air circulation, affecting plant growth. Additionally, farmers check for chemical resistance to protect crops from harmful substances that may leach from the plastic. Lastly, cost-effectiveness and the environmental impact, including biodegradability, are also taken into account to ensure sustainable farming practices.
