Advances at the plastics manufacturing level in such areas as co-extrusion and the production of specialty polymers and additives, result in the availability of plastics with improved characteristics. We have produced an agricultural photo-selective three layer co-extrusion film, manufactured at a thickness of about 200 μm. The film was made from different types of LDPE and LLDPE for each layer, and special chemical additives were incorporated into the polymers matrixes.
