What Is Polybak

PolyBak is a kraft linerboard impregnated with our proprietary polyurethane resin. It is most recognized as a balancing backer but is widely used as a crossband, overlay, and substrate for thin veneers and foils.

Features & Benefits

One of the most common pieces of feedback we receive from customers who switch over to PolyBak is “It’s so easy to use!”. PolyBak’s unique combination of superior kraft linerboard and our proprietary resin blend makes it extremely robust and strong while maintaining its flexiblity - you’re welcome to grab a sample and try to snap it! Not only is it easy to use, no chemicals of concern, most notably Formaldehyde, are used in the production of PolyBak. Additionally, PolyBak’s embodied carbon is significantly low.
