Some agricultural composite membranes suffer from perforations, cracks, and other quality issues, leading to a significant number of crop seedlings being planted in greenhouses. These substandard films are often either low-quality products or outdated inventory items. Poor-quality agricultural films lose their protective function, which can negatively impact plant growth and yield. Therefore, it's essential for everyone to choose plastic films that are as close to the production date as possible.
In addition, when purchasing agricultural films, make sure they are flat, bright, and have uniform thickness and transparency. Avoid buying thin films with watermarks, cloud-like patterns, or surface imperfections. Also, stay away from films that have air bubbles, holes, or cracks. The effective quality assurance period for agricultural films is typically one year, so it's best to buy products that are freshly produced rather than old stock.
When purchasing agricultural films, it’s advisable to go through formal agricultural companies or trusted suppliers. Always sign a proper contract and keep the receipt or invoice. This helps protect your rights in case any issues arise later. By being cautious and informed, you can ensure you're getting high-quality films that will support healthy crop growth and maximize your farming efficiency.
