FDA gives green light to Archroma PFOA–free grease-resistant coating

A new grease- and water-resistant coating developed in Switzerland by Archroma has received approval for use from the US Food and Drug Administration (FDA).

Castagaurd KST is a liquid preparation based on a cationic C6 polymer. When applied to paper or board, it provides an enduring barrier in both size press and wet-end applications. The manufacturer notes this makes it suitable for food contact items like, paper cups and plates, fast-food boxes and wrappers, soup cube boxes, and labels for oil bottles.

Levels of the toxic chemical perfluorooctanoic acid (PFOA) in the new coating agent are below detectable levels. It has already been passed for use in Europe via qualification to the German law BfR XXXVI. US approval according to the Code of Federal Regulations Title 21 176.170 will open new sales opportunities worldwide.

Frédéric Mabire, head of Archroma paper coatings division, says: ‘Archroma strives to be at the forefront of providing high-performing solutions that support greater sustainability by our customers and safer applications for consumers.

‘Having FDA approval for Cartaguard KST, in addition to the German BfR XXXVI compliance, provides our food sector customers with the assurance of a high-quality, effective and safe impregnating treatment for more eco-advanced packaging solutions.’
