The findings of an independent laboratory testing show that IPACKCHEM’s “Advanced InMould Fluorination” technology is fully compatible with both the natural and coloured highdensity polyethylene (HDPE) containers recycling streams.

This innovative technology introduces carefully controlled levels of fluorine during the HDPE extrusion blowing process to create an impermeable fluorinated barrier on the inner surface of the container. The typical thickness of the deposited layer is between 100 and 200 nm. In-mould fluorination provides bi-directional barrier to substance migration and, since it is a continuous production process, ensures dimensional and visual consistency.

The tested technology is used for rigid packaging, mainly destined for crop protection, pharmaceutical, animal health, laboratory and flavours & fragrances and Speciality Fuels.

According to the testing results carried out by the Centre Technique lndustriel de la Plasturgie et des Composites (IPC), performed as per the RecyClass Recyclability Evaluation Protocol for HDPE containers, this new technology conforms to the current European HDPE rigids recycling stream provided it is used under specific conditions.

These findings contribute positively toward the increased uptake of recyclability principles applied to HDPE packaging. They are a positive indication to the industry that functionality and design for recycling can be effectively combined to accelerate plastics circularity.
