Abstract: A novel sizing-adhesive composition for corrugating characterised in that it comprises at least one low molecular weight, water soluble polymer such as a maltodextrin, corrugating boards prepared therewith and methods of producing them.

Abstract: The present invention relates generally to sizing-adhesive compositions that combine a sizing component and an adhesive into one sizing-adhesive composition that strengthens the paper, resulting in less paper used and stored, and reduces costs. In one aspect, the process runs at lower temperatures, thereby reducing energy costs. Aspects of the present invention are directed to using these compositions in a process for applying the sizing-adhesive composition to optimize the bonding and sizing of papers. In one aspect, the process produces a corrugated paperboard with acceptable strength at a reduced cost. In another aspect, it provides a means of making a more sustainable packaging material by utilizing less paper, a renewable packaging material, and less energy compared to the current process used to produce corrugated board. In another aspect, the method allows for printability as the application of glue over the surface creates a flatter and more uniform surface.

Abstract: There is provided an adhesive composition comprising a carrier starch and a secondary starch characterised in that the carrier starch: —comprises, on a dry weight basis, less than 50% pre-gelatinised starch; and has a higher alkali sensitivity than the secondary starch. There is further provided a process for preparing such and adhesive composition.
