Abstract: Resealable systems for consumer packaging, such as food packaging, are described herein. The system includes one or more anchor points and one or more cling coatings. The anchor points can be introduced into or onto the packaging material during manufacture, such as by co-extrusion. Alternatively, the anchor points can be affixed to the packaging material after manufacture, such as with a pressure sensitive adhesive. The cling coatings can be applied to the packaging material during or after manufacture. For example, the cling coatings can be spot coated or pattern coated onto the desired location. The cling coatings are selective, that is they do not attach to themselves but only attach to the anchor point. The cling coatings transfer little or no material over time resulting in more consistent performance over time than pressure sensitive adhesives.
