One Clean Carton®, from Colbert Packaging Corporation, once again passed a series of laboratory tests to confirm its suitability for pharmaceutical and food-safe secondary packaging. New for 2026, Colbert submitted test samples using both standard SBS board and SBS comprised of 30% post-consumer recycled fiber. Both samples consisted of agri-based inks and water-based coatings and adhesives, using offset lithographic printing technology. Additionally, both carton samples included an agri-based offset printed ‘Instructions for Use’ insert glued inside.
All components of One Clean Carton, including inks, coatings and adhesives, are tested to ensure they meet environmental and safety standards to be considered clean and safe for indirect food and drug contact. In order to state the Clean Carton claim, packaging samples underwent comprehensive analytical testing. This new development of incorporating post-consumer recycled content paperboard lends new insight into the tested and verified ‘clean’ nature of this safe packaging solution.
