28 Sep 2023 --- Coca-Cola and Blue Ocean Closures are jointly testing the applicability of fiber-based closures. The Swedish environmental sustainability start-up is marketing a fiber-based packaging screw cap that is bio-based and recyclable in paper waste streams. Together, the companies are testing several parameters of the material, functionality and production system of fiber-based closures, Ulrika Ganterud Evermark, community manager at Blue Ocean Closures, tells Packaging Insights. “We are hoping to achieve a fiber-based closure that can effectively replace current plastic closures on a large scale,” says Evermark.
