As its ‘No-Carrier’ name suggests, this adhesive does not have a fully gelatinized carrier portion, but all the starch is slightly swollen. This results in lower water retention capacity and can be an advantage for papers that are difficult to penetrate, since the first water release, together with the relatively high pH, helps in opening the paper.
Having a low (or no) quantity of fully gelatinized starch granules means that 100% of the starch is active at peak viscosity, giving a maximum wet-tack. These combined features provide good glue-ability, high-bond strength, high machine speeds, shear stability and low waste.
No-Carrier adhesives are very sensitive to swelling, allowing for quick gelatinization when heated. The shorter texture helps keep the corrugator cleaner and guarantees optimal glue pick-up by the flute tips, as well as ensuring low adhesive consumption.
Using Cargill specialty starches, the solids content of your No-Carrier adhesive can be significantly increased, enabling a major increase in machine speed.
