Abstract: A mechanically strong doped polymer sheeting-high-density polyethylene (HDPE) film-that provides excellent durability, high-maintenance and photo-transforming properties for covering hotbeds and greenhouses is comprised of: a light-transforming additive based on yttrium-europium oxysulfide; a light-stabilizing agent based on polyaminosuccinate; and a polymer resin used to form the high-density polyethylene 6-mil film. A preferred embodiment includes following composition and ratios: yttrium-europium oxysulfide content is 0.05-0.5% by weight; polyaminosuccinate content is 0.1-1% by weight; the ratio of yttrium-europium oxysulfide to polyaminosuccinate ranges from 0.5:1 to 1:2; and high-density polyethylene content is over 98.5% by weight according to above percentage of the additives. The doped polymer sheeting, HDPE film, for instance, can be fabricated efficiently and compactly packaged making it suitable for mass distribution. The film has photo-transforming properties that transform UV light into the wavelength of light that promotes photosynthesis in crop plants. This film, in turn, enhances crop growth and increases greenhouse internal ambient temperature leading to an extended growing season, higher crop quality and yield and frost protection-all that coupled with excellent durability and maintenance of the polymer sheeting. Finally, all of the doped polymer sheeting properties, as well as the sheeting itself, last over a period of two or more years.
