This course begins with the history of corrugating adhesives, and then describes the purpose or function of the ingredients in modern, starch-based corrugating adhesives. These include cooked and uncooked starch, caustic, borax, and water. It details the importance of adhesive viscosity and describes the bonding process at the single facer and double facer, and the many different variables that can affect bonding. It concludes with a discussion on how water-resistant adhesives are made.

The following key questions are answered in this module:
What are the main ingredients in a typical corrugating adhesive?Contemporary corrugating adhesives typically contain a mixture of uncooked starch, caustic, borax, and water, suspended in a cooked starch paste.
Why are both cooked and uncooked starch used in corrugating adhesives?The cooked starch acts as a thickener in the adhesive mixture supplied to a corrugator, while the uncooked starch acts as the actual adhesive in the corrugated board.
What is the definition of "gel temperature"?"Gel temperature""is the temperature at which uncooked starch will hydrate and swell, or "gel," in water. It is this gelling of starch in water which allows it to act as a thickener and an adhesive.
Why is "high-shear" mixing used in the preparation of starch-based adhesives?The viscosity (or resistance to flow) of a starch-based adhesive is greatly affected by shear, and viscosity affects how the adhesive transfers to and penetrates into medium and liner. High-shear mixing subjects the adhesive to shear early on to ensure a relatively stable viscosity. It also reduces prep time.
How are water-resistant corrugating adhesives made?Water-resistant corrugating adhesives are made by adding a resin to the starch-based adhesive mixture. When this mixture is heated on the corrugator, the resin helps form bonds that are water resistant.
