How Singlet Bags Break Down
Pete's Packaging Degradable Bags
d2w and the internationally recognised droplet logo are registered trademarks used to identify a range of totally degradable, flexible and semi-rigid plastic products as well as a variety of unique additives. When included in the normal manufacturing process, these cause plastics to break down totally safely into water, carbon dioxide and a small amount of bio-mass.
How does it work?
The degradation process is initiated at the time the polyethylene or polypropylene is extruded by the inclusion of a small amount of a special additive. This additive works to break down the carbon-carbon bonds in a loss of strength and other properties. Stabilisers work to ensure that a sufficiently long useful life is provided for each specific applictaion. For example, a refuse sack might require a useful lfe of 18 months before beginning to lose its strength whereas a bread bag might only require a few weeks.
Significantly, the d2w range does not need a bilogically active environment to start degrading - this will happen even if the plastic is left out in the open air! This is very important if we are toa ddress the serious litter problems caused by waste plastic. For this reason in particular, d2w "totally degradable" plastic is superior to "bio-degradable" which requres the plastic to be in a bilogically active environment (for example, by being buried in the ground) before the degradation process is initiated.
