Michelman Collaborates with BOBST and UPM

On June fifteenth, BOBST, a frontrunner in equipment for packaging and label merchandise, will host a webinar to debate an modern new answer for the creation of high-barrier, sustainable, fiber-based meals 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 particularly well-suited for packaging, due to its excessive density, folding efficiency, and total coatability. The paper’s smoothness, porosity, and mechanical efficiency make it a superb basis for attaining optimum barrier properties.

As famous by Janne Varvemaa, Director, Products & Technology, UPM Specialty Papers, “By itself, our Solide Lucent paper will not be prepared for end-uses the place excessive boundaries are required, so a serious focus of the co-creation undertaking was growing the coating layers.”

The coating system, developed by Michelman, is constructed round a novel, multifunctional coating with glorious adhesion to the paper. This single base coating gives oxygen, moisture, and mineral oil boundaries, oil & grease resistance, and print receptivity, whereas aiding the metallization course of. This mitigates the necessity for added, separate coatings on the priming step and helps to take care of recyclability and meals contact compliance.

In addition, as a part of the entire packaging answer, Michelman has developed a spread of warmth seal coatings, optimized for various seal initiation temperatures (SITs) and additional enhancing moisture barrier properties, considering coefficient of friction (CoF) necessities for various packing traces. These coatings are utilized over the metallization layer to guard the steel and guarantee a decent seal on the package deal.

To full the system, a Michelman-designed overprint varnish (OPV) with extra moisture barrier properties is utilized over the print, bringing the general efficiency into the required vary for top barrier meals packaging with an prolonged shelf life.

“It was very inspiring working collectively with BOBST and Michelman, who’re true specialists of their respective fields…collectively we managed to create a world-leading barrier answer that provides model homeowners a packaging answer that isn’t solely sustainable, but in addition delivers on performance.”

Putting the substrate and coating system collectively efficiently is BOBST’s experience in tools design, software know-how, and optimization of the changing course of, obligatory to acquire the sleek, pinhole-free floor required for subsequent vacuum metallization. This hinges on choosing the right coating technique and tailoring the drying profile to the primer chemistry, leading to optimum movie formation and barrier properties.

“UPM’s Solide Lucent paper was a robust foundation from which to start out the event and solely required a number of modifications. We equipped the AluBond and AlOx (aluminium oxide) applied sciences, and Michelman produced the first topcoat supplies. Overall, the in-depth technical understanding we every delivered to the desk complemented each other,” explains Nick Copeland, Research & Development Director, BOBST.

Thierry Van Migem, Sales Director, EMEA, Michelman, agrees. “By working collectively and not in silos, we’re in a position to determine points and modify quickly, selling an agile method of working and enhancing pace to market. By uniting our respective experience, the entire efficiency of the oneBARRIER FibreCycle answer is best than we may have achieved individually.”

Varvemaa concludes, “It was very inspiring working collectively with BOBST and Michelman, who’re true specialists of their respective fields. I discovered the cooperation fruitful and open, with easy and trusting communications. I consider that collectively we managed to create a world-leading barrier answer that provides model homeowners a packaging answer that isn’t solely sustainable, but in addition delivers on performance.”
