CA 2732837

A UV-curable pressure sensitive adhesive, a package having an adhesive-based reclosable fastener including the pressure sensitive adhesive, and a method of forming the package is described herein. The package includes a cavity and opposing panels configured to cover an opening to the cavity. The reclosable fastener is a UV-cured pressure sensitive adhesive comprised of one or more UV-curable acrylic oligomers, one or more tack control components, and, optionally, an elastomeric material. An adhesive component ratio defines an effective ratio made up of the weight percent of the UV-curable acrylic oligomer relative to the sum of the weight percents of the tack control component and elastomeric component, where the ratio provides a fastener with a first peel adhesion and subsequent peel adhesions effective to form the adhesive-based fastener into a reclosable fastener.
