In-mould fluorination is an environmentally friendly technology
- Recyclable as normal HDPE
The molecular level of in-mould fluorination enables recyclability as normal HDPE
Fluorine gas used during the in-mould fluorination process by the IPACKCHEM Group is environmentally friendly and thus is NOT regulated in either the Kigali Amendment to the Montreal Protocol of February 2017 or the original Protocol of September 1987 which covers ChloroFluoroCarbons (CFCs) as ozone depletants and HydroFluoroCarbons (HFCs) classified as substances with very high Global Warming Potential (GWP) respectively.
Examples CFCs and HFCs with GWP ratings
*HFC-134a : Required phase out as of 2017 (Kigali amendment). By 2024, usage should be cut by 40% and more in the following years.
The process of in-mould fluorination uses a dilute Fluorine/Nitrogen mix and involves a chemical reaction with HDPE that forms the container’s inner surface. The residue gas is completely neutralised (scrubbed) using calcium carbonate to produce environmentally neutral calcium fluoride (CaF2) on its surface. This is classified as a reused waste stream and has no ozone depletive properties.
