Abstract
Corrugated paperboards are prepared for corrugation and adhesive bonding of mediums and liners by exposing the mediums liners and adhesives to radiant energy from a thermal source ranging from 1100.degree. C. to 2300.degree. C. and emitting a dominant wavelength in the range of 2.1 to 1.0 microns. The speed of adhesive bond development is increased. Polymeric adhesives may be used as alternatives to conventional starch based adhesives.
