Agricultural film also see shelf life

Some agricultural composite membranes have perforated, cracked and other quality problems, resulting in a large number of crop seedlings planted in greenhouses. These problematic films are either inferior products or already aged inventory products. Because poor quality agricultural film will lose its protective effect, it is important to remind everyone to buy plastic films that are close to the date of production.

In addition, agricultural films should be purchased that are flat and bright, uniform in thickness, and uniform in transparency. Do not buy thin films with watermarks or cloud-like markings on the surface, and films with air bubbles, perforations, cracks, and other defects. The effective quality assurance period for agricultural films is one year. Consumers should try to purchase films that are closer to the date of production and avoid buying old stock products. In addition to the purchase of agricultural film to the formal agricultural company, signed a good contract and retain the voucher, in order to protect rights later.
