Panel Edgebanding

Our edgebanding machines use PUR glue, which provides excellent tape-to-panel adhesion and seals the edge, protecting against water ingress. We can edgeband panels as narrow as 20mm and up to 60mm in height with various edging options including solid wood, veneer or ABS tape. PUR glue forms a solid bond with immediate adhesion, possesses superior flexibility and is water-impenetrable.
