Corrugated board is a construction whose strength depends on its "bonding points".

The strength depends on:

The bonding quality determines the final strength of the corrugated board.

Running speed

Glue penetration

Paper quality

Temperature

Glue formulation

Type of starch

Mechanism of Water ResistanceMechanism of Water ResistanceMechanism of Water ResistanceMechanism of Water ResistanceWater resistance is achieved by a cross linking reaction between the starch/cellulose and the resin, in which a grid of covalent bonds is formed.The grid is formed after gelatinization of the glue. This chemical bond is stable in water, and thus the glue acquires water resistant qualities.

The reaction is dependent on temperature and PH.

The water resistance of the glue of corrugated fiberboard is measured by the length of time during which a predetermined combination of glue lines, immersed in water, resists the pull of a suspended weight in the plane vertical axis of the board, at a right angle to the glue lines.

Green Bond and High SpeedGreen Bond and High Speed

Side delamination issues arising on the corrugator is well known, in order to reduce this phenomena the decreasing of the corrugator’s speed is needed.

The result is lower productivity and line efficiency,and higher costs.

Enhanced adhesive performanceEnhanced adhesive performance


Side delamination can be overcome by increasing the tackiness of the wet glue leading to better bonding which allows working at higher speeds.

Thus productivity and line efficiency increases, and costs decrease.

Green Bond and High SpeedGreen Bond and High Speed


Enhanced PropertiesEnhanced PropertiesEnhanced PropertiesEnhanced PropertiesA group of resins specifically designed to produce early green tackiness. (CP-88/LV CP-88/LA, CP-88/LV20D)

These polymers are film formers and possess a high concentration of polar chemical groups which cling to the cellulose of the board by hydrogen and physical bonds.

The strong bonds allow higher running speeds with less waste, and accelerate production.


Enhanced adhesive penetration – CP-88/PEnhanced adhesive penetration – CP-88/P

This additive enables rapid migration of liquid starch adhesive into paper assisting the bonding of recycled liners, liners coated with synthetic polymers, preprinted liners and other difficult to penetrate substrates.


This additive Improves bond quality and corrugator speeds on all grades of paper including heavy weights, double wall and triple wall.
