ROQUETTE introduces VECTOR® N

A range of specialty starches for the corrugated board industry.

Since the introduction of the Stein-Hall process and the replacement of silicate by high-solids starch based adhesives, machine speed has dramatically increased thanks to starch’s ability to bond quickly and safely different kinds of papers on any corrugator. These adhesives have not yet reached their bonding limits on modern single facers.

However there were still areas for further starch development in corrugating including sectors such as micro-flute board, agricultural boxes, double-wall board, heavy-duty board and water-resistant board. ROQUETTE is introducing a new technology and a new starch range to the traditional range of products for the corrugating industry. This is to complement the well-known capabilities of maize, wheat and potato starches.

1. Maize starch is the most versatile starch currently used and is able to bond securely in many different conditions. It is considered limited in terms of speed for double-wall production. However it resists heat and prevents brittle bonding at low speeds and is the most widely used starch in the corrugating industry.
2. Wheat starch gives higher speed in double wall production compared to maize starch but at the expense of brittle bonding at the low speeds experienced during order changes.
3. Potato starch is currently the best performing starch for double wall and triple wall production. It is used as secondary starch on middle and top tray of the glue machine to improve production speeds of heavy duty board. Potato starch is not suitable as a carrier starch and needs to be used in conjunction with maize starch; also it cannot be used at the single facer.
