FLUORINATED HDPE CONTAINER
Fluorinated HDPE containers may be produced using one of three fluorination technologies: Advanced in Mold Fluorination, Post Fluorination, or Plasma Fluorination. These technologies all replace hydrogen ions with fluorine ions in the polymer chain, creating an effective barrier against chemicals that would otherwise penetrate conventional HDPE.
Of these technologies, only Advanced in Mold Fluorination is consistent and compliant with recent proposals to restrict the use of PFAS. Fluorinated containers are made of a mono material barrier packaging that can be recycled just like conventional HDPE.
Depending on their intended usage and transportation requirements, HDPE barrier containers may or may not be UN approved. UN approval requires rigorous testing, including drop testing with a cap applied from a specific height, hydraulic testing to a specific pressure, and stack testing over a defined time and top load pressure. Containers must also undergo further testing for UN chemical approval in one of five “model liquids” groups. The UN markings on the container indicate its mechanical performance.
