PFAS in Food-Contact Packaging: What the test results wreally mean
Which test is appropriate for a particular packaging material? What does an elevated fluorine level indicate? And when are further PFAS analyses required? For companies, it is crucial to select the appropriate test and interpret its results correctly. A single measurement value alone does not answer every question: What matters is which substances the method detects and to which material the result applies.
From initial screening to targeted analysis
A meaningful PFAS testing strategy therefore begins even before the measurement takes place. The test objective, packaging structure, and available material information determine which sample is tested and which analytical parameters are appropriate. Separable packaging components, coatings, and multilayer composites require an assessment tailored to their specific structure.
Depending on the research question, an initial screening can provide guidance, or a more in-depth total or individual substance analysis may be appropriate.An elevated fluorine value does not automatically indicate the presence of specific PFAS. It may initially indicate a need for further clarification. The findings and the original research question determine which additional tests are necessary.
Reliable data for further evaluation
Transparently documented analysis results provide a foundation for internal material evaluations, quality assurance, supplier communication, and technical documentation. It is important to distinguish between the analytical testing and the final regulatory evaluation of food contact packaging.
Our technical article shows how to develop a concrete PFAS testing strategy, what is important when selecting samples, and what conclusions can be drawn from the various tests. Learn how individual measurement values can be used to build a reliable analytical data foundation.
