Archroma has received FDA food contact approval for its new Cartaguard KST oil and grease resistance additive manufacture of paper and board for food packaging.
The PFOA-free additive provides high levels of oil, grease and water resistance to paper and board.
It also complies with the recommendations of the German BfR XXXVI for use as a surface refining and coating agent in paper and board intended for food contact applications. These two approvals allow it to be used in global markets.
Cartaguard KST liquid is based on a cationic C6 fluoropolymer which provides an ultra-strong and long-lasting barrier to grease and water. Its performance properties and environmental profile make it particularly suitable for use in both size press and wet end applications to produce fast food boxes and wrappers, soup cube boxes, butter wrap and oil bottle labels.
It is also suitable for use in production of moulded pulp plates and cups, and in pet food packaging.
“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,” commented Frederic Mabire, head of global product management coating chemicals, paper solutions business, Archroma.
Cartaguard KST is approved by the US Federal Food and Drug Administration under 21 CFR 176.170 for use as a grease resistance treatment employed prior to, or after sheet formation for paper and paperboard.
