Archroma announces FDA approval for the use of its new Cartaguard KST in the manufacture of paper and board for food packaging. The effective oil, grease and water resistance additive is also compliant with the recommendations for use as a surface refining and coating agent in paper and board intended for food contact applications. The newly launched Cartaguard liquid is based on a cationic C6 fluoropolymer which excels at providing a strong and long-lasting barrier to grease and water. Its properties and environmental profile make it particularly suitable for applications to produce fast food boxes and wrappers, soup cube boxes, butter wrap and oil bottle labels. Having FDA approval in addition to the German BfR XXXVI compliance provides food sector customers with the assurance of the quality, effective and safe impregnating treatment for more eco-advanced packaging solutions. This material is approved by the FDA under 21 CFR 176.170 for use as a grease resistance treatment employed prior to, or after sheet formation for paper and paperboard.
