US company National Starch & Chemicals has developed a new, waterborne, tackified, acrylic, pressure sensitive adhesive which is suitable for paper or film labels in applications with temperatures down to -20 degrees F, making it ideal for frozen packaged foods.
As well as adhering securely to various substrates in low temperature environments, this speciality adhesive converts cleanly, dispenses well, and provides an ideal balance of peel, shear and tack, claims the company. Additionally, when the adhesive cures, it becomes clear.
Called Nacor 38-463A adhesive, this product may be applied through the use of a slot die or reverse roll. Viscosity and rheology modifications can be made to customise the adhesive to meet individual coater requirements, according to the manufacturer, National Adhesives, which is a division of NSC.
The dry film components of the adhesive comply with the compositional requirements of the FDA Indirect Food Contact Regulation on adhesives, making it suitable for the increasingly popular frozen and refrigerated foods sector.
