1. A machine for converting a web of preformed pouches into inflated dunnage units, the pouches defined by transverse seals extending from a remote edge to within a predetermined distance from an inflation edge, the machine comprising:
a sealing arrangement positioned to provide a longitudinal seal that intersects the transverse seals to close the preformed pouches and form a dunnage unit, the sealing arrangement having at least two sealing belts, each belt powered by a drive roller and positioned so that respective first sides engage a surface of the web and pull the web through sealing elements positioned on either side of the web;
a heating element on a second side of the first belt not engaging the web, wherein the heating element is a substantially flat wire comprising at least one relatively higher resistance portion and at least one relatively lower resistance portion;
a compliant material on a second side of the second belt not engaging the web;
wherein as the web passes between the heating element and compliant material, imperfections in the web are smoothed by the compliant material and the layers of the web are sealed by the heating element.
