Biodegradable Shrink Wrap
Biolefin™ Oxo-Biodegradable Polyolefin is a standard polyolefin to which mineral salt additives have been included, rendering the film capable of absorbing water. Once discarded properly, it ends up in a landfill, where, when exposed to light, wind, water, heat, and the native microbial organisms found in a landfill, the water-enriched film is capable of being assimilated by those micro-organisms, which then excrete it as biomass, with no discernable plastic particulate.
So, what begins as a chemical process, with the mineral salts enabling the film to absorb moisture, ends as a biological process, as the microorganisms consume and convert the film to biomass.
The latest version of the film, Biolefin™ 2.0, has been tweaked to degrade in 2-3 years after discard.
