HDPE fluorinated container

Fluorinated barrier

Introduction of carefully controlled levels of fluorine during the HDPE extrusion blowing process to create an impermeable fluorinated barrier on the inner surface of the container

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
