To prevent agricultural plastic films from being damaged or torn, follow these practices: 1. Choose high-quality films with UV stabilizers to resist degradation from sunlight. 2. Properly install the films to avoid sharp objects or rough handling that could cause punctures or tears. 3. Regularly inspect the films for any signs of wear or damage and repair them promptly. 4. Use windbreaks or barriers to reduce the impact of strong winds that can cause the films to flap and tear. 5. Keep the area around the films clean to prevent debris from scratching or damaging the film. 6. Use appropriate weights or anchors to secure the films and prevent them from lifting and tearing. By implementing these measures, you can extend the life of your agricultural plastic films and maintain their effectiveness.
