An impermeable corrugator belt for a corrugator machine includes a multi-layer base fabric having a layer of a polymeric resin material on one of its two sides. When arranged in the form of an endless loop, the side having the layer of polymeric resin material is on the inside thereof. The polymeric resin material renders the corrugator belt impermeable, and therefore suitable for use on a corrugator machine having air-bearing pressure zones. Instead of a multi-layer base fabric, a spiral coil carrier may be used as the base of the corrugator belt.
