Tissue and Towel Adhesives
Adhesives are a critical component of any paper towel or bath tissue manufacturing operation. Water-based adhesives designed for paper towel and bath tissue manufacturing are used for core winding, ply bonding, core start up, and tail-tie applications. These adhesives are unique in that they need to have excellent tack when wet to increase efficiency but dry to a tack free film to prevent the roll from having a sticky or dirty effect. In addition, the adhesives used for tissue and towel manufacture need to be easily separated from the pulp fibers during recycling. These factors play a crucial role in the adhesive formulators choice of resin for water-based tissue and towel adhesives.POLYOX™ Water Soluble Resins
POLYOX™ Water Soluble Resins are large molecular weight poly ethylene oxide polymers that are ideally suited for use in water-based tissue and towel adhesives. Aqueous solutions of POLYOX™ have a high degree of wet tack and dry to form tack free residues that leave tissue and towel rolls feeling soft and clean. In addition, dried POLYOX™ films remain water soluble and are easily dissolved in the process water during paper recycling. This leads to paper towels and bath tissue that is much easier to recycle. Common grades of POLYOX™ used for tissue and toweling adhesives are listed below.
