Degralen® and D2W
Traditional polymers (along with polyethylene) have large molecules which micro-organisms have a difficult time absorbing. Over time, however, as polymer chains are oxidized their length decreases and enzymes of micro-organisms begin to break them down. Unfortunately, this process is very slow and can last for years which make traditional plastics practically non-degradable.
Oxo-degradable polymers contain in a special substance (prodegradant additives) which accelerates the oxidation of polymers as they come in contact with sunlight, oxygen, and mechanical fluctuations (wind).
Common bags types manufactured from Degralen are: Patch Handle Bags, Soft Loop Handle Bags, Die Cut Bags, and T-Shirt Bags.
DegralenDegralen® is a registered trademark of Extrapack for an oxo-degradable polymer that degrades in the environment within 12 to 24 months. It is produced under the license of EPI Environmental Plastics Corp. (Canada), a pioneering company in the field of oxo-degradable polymers. More information about Degralen® can be found on Degralen.EU.
Extrapack use two types of Degralen: Degralen-L and Degralen-H with physical properties like LDPE and HDPE respectively.
