New fluorine-free grease barrier
FOLBB has developed a new innovative barrier quality, to keep pace with recent Northern European legislation and market trends.
In the course of 2021, FOLBB replaced the current grease barrier qualities - which are free from perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) – with a completely fluorine-free grease barrier. The performance and the grease resistance of the new product will be identical or even better than our current products.
New barrier performance evaluation method
The effectiveness of the new grease barrier is tested according to DIN 53116. With this method, we simulate a worst case scenario: A large amount of palm kernel fat solution is applied onto the barrier board, and the duration of the grease resistance (until grease stains appear on the top side) is measured. This allows to evaluate the grease resistance for the shelf-life of a product in only several hours. The new fluorine-free grease barriers fall under category III. Thus, the new quality will have the description III instead of the KIT Value in their respective names. The current “KIT-method” is not applicable for measuring the barrier performance of a fluorine free barrier.
