Michelman collaborates with BOBST & UPM on sustainable food packaging innovation

On 15th June, BOBST will host a webinar to discuss an innovative new solution for the creation of high-barrier, sustainable, fibre-based food packaging, developed in conjunction with Michelman and UPM Specialty Papers.

Called oneBARRIER FibreCycle, its base substrate is UPM Solide Lucent™, a responsibly sourced and recyclable kraft paper especially well-suited for packaging, thanks to its high density, folding performance, and overall coatability. The paper’s smoothness, porosity, and mechanical performance make it an excellent foundation for achieving optimum barrier properties.

Janne Varvemaa, Director, Products & Technology, UPM Specialty Papers, said, “By itself, our Solide Lucent paper is not ready for end-uses where high barriers are required, so a major focus of the co-creation project was developing the coating layers.”

The coating system, developed by Michelman, is built around a novel, multifunctional coating with excellent adhesion to the paper. This single base coating provides oxygen, moisture, and mineral oil barriers, oil & grease resistance, and print receptivity, while aiding the metallization process. This mitigates the need for additional, separate coatings at the priming step and helps to maintain recyclability and food contact compliance.
