Film extrusion: Pressure-sensitive adhesives tackle broad usage range

Three new pressure-sensitive adhesives (PSAs) have been added to the range offered by this supplier, offering converters solutions to a broad array of package labeling. All of the new PSAs are supplied by Omnova Solutions (Fairlawn, OH), which develops and markets emulsion polymers, specialty chemicals, and decorative and functional surfaces. These PSAs are branded NovaCryl and are marketed to processors and converters of polyvinylchloride (PVC) film, tape, and labels.

NovaCryl PS-P 180, NovaCryl PS-V 700 and NovaCryl PS-R 50 adhesives cover varying levels of adhesion, from permanent to "ultra-removable," and each is free of alkylphenol ethoxylate (APE)-type surfactants. APEs have grabbed some negative attention as two alkyphenols, nonylphenol and octylphenol, are suspected hormone disruptors.

The three new NovaCryl PSAs are available as a base polymer or a coater-ready formulation. NovaCryl PS-P 180 water-based acrylic  polymer is designed for permanent PSA applications, such as clear film labels on transparent bottles for shampoo, household cleaners, and other toiletries, as well as over-laminates and protective films.

NovaCryl PS-V 700 water-based acrylic PSA base polymer for permanent PVC film applications brings with it plasticizer resistance, good UV stability, and clarity. This PSA builds adhesion over time but remains cleanly removable from most surfaces, so that it is marketed for use in applications such as vinyl graphics, labels, wall decals and stickers, indoor and outdoor advertisements, over-laminates, and clear vinyl protective films.

The third material, NovaCryl PS-R 50, is a water-based adhesive that maintains adhesion of less than half a pound. Such easy-to-remove characteristics are useful in, for example, glass protective films, temporary indoor promotional posters and decals, and protective films for automotive and consumer electronic display applications (see photo).
