One Clean Carton®, from Kenosha, Wisconsin based Colbert Packaging Corporation once again passed a series of laboratory tests to confirm its suitability for pharmaceutical and food-safe secondary packaging. New for 2021, in addition to re-testing its standard Clean Carton paper stock, Colbert submitted test samples for a paperboard containing 30 percent post consumer recycled fiber.
All components of One Clean Carton, including inks, coatings and adhesives, are water-based, ensuring they meet environmental and safety agency standards to be considered clean and safe for indirect contact with the products they contain. In order to make the Clean Carton claim, Colbert Packaging surpassed minimum standards by submitting to comprehensive analytical testing to obtain documented proof that One Clean Carton meets these requirements.
“Today’s Pharma and Consumer product managers are tasked with sourcing environmentally-friendly packaging,” says Lon Johnson, vice president of sales and marketing. “We’re pleased to announce the test results showing One Clean Carton, made from paperboard consisting of 30% post consumer recycled fiber, has tested FDA compliant for food and pharmaceutical products. This good news supports customer sourcing criteria and our ongoing commitment to sustainability and stewardship.”
Colbert’s One Clean Carton is derived from the following components:
Paper is the foundation for One Clean Carton. Two separate samples were tested. The first, Colbert’s standard SBS, uses Candesce® CIS, ensuring only virgin fiber with no mechanical pulp in a middle ply. The composition of this paper provides for superior performance on press, resulting in less waste and lower consumption of raw materials and ink, which supports sustainability and recyclability as an added benefit.The second set of samples utilized ReMagine™, a premium paperboard with 30 percent post-consumer recycled fiber. ReMagine has been shown to deliver superb print quality and on press performance for SBS folding carton and print applications. Barak Bright, director of product management at Clearwater Paper says, “I believe the inclusion of ReMagine in the Colbert One Clean Carton campaign is a pivotal moment in the evolution of SBS.”
The water-based inks comply with the Swiss Ordinance regarding food-safe inks and coatings.
The aqueous coatings originate in the United States and meet or exceed U.S. federal and state guidelines.
Finally, Clean Carton water-based adhesives meet or exceed V.O.C. emission requirements.
Demonstrating its commitment to environmentally-friendly paperboard packaging and corporate best practices, Colbert Packaging first submitted One Clean Carton samples for independent scientific testing in the fall of 2018, and continue periodic testing.
