Bobst, Michelman Partner on AlOx High Barrier Films and Topcoat Solutions
In response to industry demand for high-barrier AlOx transparent films to be better protected during the conversion process, Bobst and Michelman have collaborated to develop a unique solution combining topcoats with AlOx coatings to prevent barrier performance loss during conversion processes such as printing and lamination.
Combining Michelman’s expertise in the field of developing coatings with Bobst’s machinery conversion know-how in the fields of vacuum metallizing, coating lines, lamination and both gravure and flexo printing, the two companies have worked together to create an innovative system for AlOx high-barrier clear films. Two topcoat formulations have been developed by Michelman – one is a topcoat which gives protection to the AlOx layer during conversion and the second is a barrier-enhancing topcoat that offers all the benefits of a protective topcoat and also provides additional barrier functionality improvements in both OTR and WVTR to prolong package content shelf life.
Commenting on this collaboration, Juan Cano, Sales Director for the Vacuum Coating & Metallizing Product Line at BOBST said
“Our simple to operate and efficient AlOx vacuum deposition process for single-layer application onto clear films has been well-established in the market over the last five years and is still in high demand,” says Juan Cano, sales director for the vacuum coating & metallizing product line at Bobst. “However, finding a solution to protect the AlOx coated films, produced by our metallizers, during more complex conversion processes in the flexible packaging industry has been a priority for our customers in order to retain their high-barrier properties. Working in collaboration with Michelman and having the advantage of drawing on their extensive experience in the field of coatings has enabled development and application of these two unique topcoats to AlOx coated films using specially modified coatings platforms from our sister company Bobst Italia. We are excited to launch this innovative and fully integrated AlOx Conversion process into the market.”
Robin Cooper, strategic program manager at Michelman adds: “We are pleased at the opportunity to work with Bobst in this unique opportunity to introduce new barrier systems into the market. Here, a unique collaboration opportunity has allowed us to combine our expertise with leading OEM Bobst to bring more high performance solutions to our joint customers seeking high levels of OTR and WVTR barrier.”
