A Low-tack, UV-cured Pressure Sensitive Adhesive Suitable for Reclosable Packages
Patent - This patent describes a UV-cured pressure sensitive adhesive including one or more UV-curable acrylic oligomers, one or more tack control components, and, optionally, an elastomeric material. The adhesive includes an adhesive component ratio of the various adhesive components effective to provide desired first peel adhesions and subsequent peel adhesions. The package includes a cavity and opposing panels configured to cover an opening to the cavity. 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.
