ABSTRACT:
The invention relates to a curable aldehyde resin and starch composition useful as a saturant and laminating adhesive for paperboard products, including dual arch corrugated cardboard. The aldehyde resin to starch ratio is from approximately 7:5 to 5:1 by weight. By the present invention is produced corrugated paperboard which has substantially improved crush strength over that obtained with polyvinyl acetate adhesives, and higher moisture resistance than either polyvinyl acetate or starch adhesives.
