Fluorinated HDPE bottle technology has advanced through one of three types of fluorination techniques, namely A-IMF, Post Fluorination, and Plasma Fluorination. The primary function of these techniques is to replace hydrogen ions with fluorine ions in the polymer chain, creating a barrier against hazardous chemicals that would typically penetrate conventional HDPE bottles.

Advanced in Mold Fluorination is the most reliable and in compliance with recent regulations aimed at limiting the use of PFAS in plastic products. As a result, it is the recommended technique for achieving fluorination in HDPE bottles.

Fluorinated HDPE bottles are a mono-material barrier packaging that is easily recyclable, just like conventional HDPE bottles. It provides the required barrier properties while remaining environment friendly.

The UN may approve fluorinated HDPE bottles for the transportation of hazardous goods, depending on their usage and transportation requirements. However, the certification process is stringent and includes drop testing, hydraulic testing, and stack testing over a defined time and top load pressure, along with an approved cap/closure. The UN markings on the bottles show their mechanical performance. Further testing is required for UN Chemical approval in one of five model liquids groups.
