Steam Remoisturizing Technology for Paper Based Label Manufacturers

To remain competitive in today’s marketplace, paper based label manufacturers must be able to produce a stable, flat product. This requires controlling the moisture content in all layers of the final product to equilibrium.

Coated or laminated paper processes typically require high temperature curing which creates moisture imbalances between the paper substrate and the coating or laminated layer(s).  These imbalances, if significant, cause static electricity buildup, web brittleness and curl. All of these conditions can negatively affect product quality and production throughput. 

In the current economy, label producers need to coat efficiently, effectively, and with improved economies for margins and the marketplace.  One often overlooked, yet important piece of equipment in this equation is the remoisturizer.  Identifying what conditions are critical in this unit operation for maintaining process stability is essential.  Conditions to consider include: the proper amount of moisture for the web; machine speed and protection of the coated surface from contamination.
