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.
