Measuring the viscosity of starch glue for the production of corrugated cardboard.

A blog published by: Sofraser.

Classified in polymer product family, starch is used in a large part of industrial production, especially in the packaging industry. Starch glue is principally employed for bonding paper products and is used in the manufacture of corrugated board.

Viscosity of starch glue in bonding paper products

Corrugated cardboard is one of the most important applications using starches glue. Corrugated board results by the adhesion of a fluted layer of paper between two flat layers. Starch is used as an adhesive in these different liners.

The control of the adhesive viscosity during the process is critical. When the viscosity is out of the acceptable range, it impacts end-product quality, and imperfections are important. (Read more)
