HDPE fluorinated container

PTFE like fluorine barrier

Introduction of carefully controlled levels of fluorine during HDPE extrusion blowing process to create a PTFE like (Polytetrafluoroethylene) barrier.

Why in-mould fluorination for your rigid plastic containers?

In-mould fluorination is recognised by the market as a superior barrier technology as

  • It uses HDPE, a widely available polymer
  • Barrier is formed by a chemical modification of the inner surface only
  • The molecular level of in-mould fluorination enables recyclability as normal HDPE
  • In-mould fluorination provides bi-directional barrier to substance migration
  • In-mould fluorination is a continuous production process ensuring dimensional and visual consistency
