A cup holder sleeve is formed in accordance with the method comprising the steps of feeding corrugated paperboard into a lithograph press, the corrugated paper including a first surface and a second surface; engaging the corrugated paperboard with an impression cylinder having a perforated metal plate secured thereabout such that the corrugated paperboard is de-bossed with air channels formed in the first surface of the corrugated paper; die cutting the corrugated paperboard into a long, flat band; and gluing first and second side edges of the band at overlapping surfaces of the first and second side edges to create the resulting cup holder sleeve with the first surface defining the inner surface of the resulting cup holder sleeve.
