Corn starch is the most widely used starch because of its availability and versatility. It can be used in all glue processes and gives a very 'forgiving' glue, allowing for a less than perfect control of the corrugator and reducing the amount of delamination caused by brittle bonding when the corrugator slows down.
Starch-based adhesives for corrugated boxes have used as corrugated adhesives since the beginning of the industry. The adhesion base is on a hydrogen bond between starch molecules of the glue and cellulose molecule of the paper. A corrugated board is a construction whose strength depends on its "bonding points."
