Chemical Profiling
Chemical analysis procedures used in laboratory testing identify the presence of persistent fluorinated organic compounds commonly applied as grease-resistant coatings on paper and paperboard. Performing PFAS screening on food-contact materials ensures that packaging does not release harmful, non-degradable chemicals into the human food chain or the environment. This testing acts as a decisive gateway for packaging converters who must verify that their raw materials are free from added fluorochemicals.
It is increasingly demanded by retailers and regulatory bodies as awareness of chemical persistence rises.
Detection Method
Multiple methods are used to detect both total fluorine and specific target compounds in the substrate. During PFAS screening, labs often use total organic fluorine analysis as a preliminary step, which is followed by chromatography if high levels are detected. This combination allows for both rapid high-volume testing and precise identification of individual regulated molecules.
It prevents false negatives by screening for the presence of a wide range of synthetic fluorine compounds in one run.
Supply Assurance
Procurement departments use this testing to audit their supply chains and verify mill compliance. Having independent laboratory proof of a negative result helps converters maintain their status as preferred suppliers to major food service brands. This screening is a standard part of risk management in food packaging sourcing.
