Wilsonart's high pressure decorative laminate (HPDL) is regarded as the most environmentally friendly surface laminate on the market today. HPDL is a paper-based product created by bonding melamine-impregnated decorative papers to layers of resin-treated FSC® certified kraft paper under high heat and pressure. In the press, decorative papers are permanently bonded to FSC® certified kraft paper to form a sheet of laminate. Laminate is made up of several components and key ingredients. We utilize Wilsonart's HPDL by adhering it to either a CARB II compliant birch multiply or to our 100% recycled and CARB II compliant particle board with a matching Wilsonart edge band.
