The Blue Ocean Closures Paper-Plug fiber-based opening system has been developed by the Sweden-based company as its solution for the packaging industry that targets demand for low-cost, sustainable solutions. The system is designed with food applications in mind including frozen and dry as well as ingredients and health supplements, while also being versatile enough to support personal care and home care applications. The closure sets itself apart from tear-style openings and separate plastic fitments in favor of a fiber-based solution that can be integrated directly into cartons and corrugated board structures.
CTO Staffan Andersson spoke on the Blue Ocean Closures Paper-Plug fiber-based opening system saying, "Paper packaging has historically been strong in surfaces and structure but limited in functionality wherever advanced opening, dispensing and reclosure features were needed. With Paper-Plug, we want to expand what paper packaging can become."
