On this page, you will find information and regulatory updates regarding PFAS. Please check this page frequently for the most recent developments and details.
Inhance Technologies, a Responsible Care™ company, has served customers with its fluorination technology for 40 years, and is committed to continuing safe operations that are protective of its workers, local communities, the public and the environment. Fluorinated barrier packaging is critical in protecting the environment by preventing permeation of container contents through evaporative emissions.  Inhance Technologies’ barrier technology annually prevents more than 25,000 metric tons of chemicals from being released into the environment that would otherwise occur due to packaging permeation.
Inhance Technologies does not utilize – and has never utilized – PFAS in any of our processes. Inhance Technologies’ fluorination technology is compliant with FDA regulation 21CFR 177.1615 and applicable REACH regulations. Any PFAS, if present, are unintended impurities that serve no commercial purpose.
Quantitative risk assessments carried out by highly credible third-party experts show that fluorination of packaging and fuel systems do not present an unreasonable risk to the environment or human health. Sectors that heavily rely on Inhance Technologies’ fluorination technology include crop protection, fuel systems, and healthcare (e.g., rigid cold chain packaging that ensures the safe transportation of vaccines and vital biologic medicines).

Over the past two years, Inhance Technologies has conducted significant research and development and voluntarily implemented measures to further reduce the potential for PFAS formation, achieving non-detect levels in almost all of the plastic packaging articles treated. Through its continuing investments, the company expects to reach 100% non-detect for all PFAS in question.
Fluorinated barrier packaging represents less than 0.2% of the 15 billion pounds of polyethylene packaging produced annually in the United States, and is vital to environmental and human health protection, product efficacy, and sustainability.
