Résumé : |
Tackifiers are readily accepted as a vital component in the formulation of optimum performance adhesives. Eka Chemicals has recently developed a new series of Snowtack[TM] tackifier dispersions for water-based pressure sensitive adhesives (PSAs) that have improved cohesive strength. The water-based segment has shown the strongest growth in the last 15 years compared to hot melt and solvent PSAs. This was initially due to lower costs, reduced flammability and environmental considerations. Continued growth has been due, in part, to the development of polymer and tackifier dispersions that meet today's technology requirements for coating, converting and performance.
The key stages in the production of a water-based PSA label are as follows :
- Compounding - the blending of the tackifier, polymer and other additives, such as defoamers and wetting agents;
- The resultant adhesive is pumped to the coater, where the coating head could be one of many configurations but is predominantly slot die or reverse gravure;
- The adhesive is applied to the carrier and passed through drying ovens at speeds of up to 500 m/min;
- The dried adhesive is laminated and wound as master rolls; and
- These rolls are subsequently slit into smaller rolls prior to die cutting of the label shape and design printing. |
