The polymer molecules of crosslinking agent will replace the hydroxyl groups in starch molecules, forming stable crosslinking. Starch molecules are surrounded by crosslinking agent molecules, enhancing their ability to resist heat and shear, thereby maintaining viscosity stability during cycling. Due to the substitution of hydroxyl groups in starch molecules, the hydrophilicity changes to hydrophobicity, making it easy to dehydrate during drying, which increases the drying speed and thus increases the machine speed. Crosslinking agent molecules are prone to affinity with fiber molecules, thereby helping to improve adhesive strength. Due to the slow and irreversible reaction process of crosslinking agent molecules, their adhesive and moisture-proof effects will gradually increase when the corrugated board leaves the production line. After the reaction, a fast and moisture-proof film is formed and the paper board becomes hydrophobic.

Features

1.Increase machine speed and production capacity

Starch adhesives added with crosslinking agent  has excellent film-forming and permeability properties, giving the starch good initial adhesion, thereby increasing running speed and production capacity.

2.Improve the water resistance of corrugated cardboard

It can crosslink with starch, act as a bridge, and protect the starch adhesive from hydrolysis when the cardboard is damp, thereby improving the water resistance of the cardboard. This is particularly important for export packaging, household appliances, tobacco or fruit packaging, etc.

3. Improve the quality of corrugated cardboard

After cross-linking, the starch adhesive has good viscosity stability, increased film-forming strength, which can reduce the finished product defects such as moisture and warping of the cardboard. In addition, crosslinking agent molecules are prone to affinity with fiber molecules, which can help improve bond strength to some extent.

4. Reduce comprehensive costs

The use of crosslinking agents in the starch adhesive can effectively reduce related costs such as defective rate, steam and adhesive consumption.
