  • Method for protecting plants using polymeric film containing anhydrous borax
    Patent number: 4651467
    Abstract: Polymeric compositions particularly suitable for agricultural purposes are disclosed. These compositions contain at least 80% of either a polyolefin such as polyethylene or a copolymer of ethylene. A 0.5-15% additive containing the bond boron-oxygen such as anhydrous borax imparts a desirable opacity to these polymers in the high wavelength infra-red region of the spectrum, while not substantially interfering with the visible light necessary for photosynthesis.

  • Method for growing plants or crops utilizing polyolefin covering material
    Patent number: 4170087
    Abstract: Polyethylene or EVA copolymer film which includes up to about 15% by weight of an additive preferably a mixture of alunite - aluminum hydroxide is disclosed for particular use as a cover for agricultural purposes. The disclosed film has improved properties which provide growth of plants and/or crops by reducing thermal losses to the atmosphere and by minimizing shadow formation. The physical characteristics of the film are equal to or better than conventional films.
