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.

1. A resealable packaging, comprising a first portion comprising one or more anchoring sites, anda second different portion comprising one or more cling coatings, wherein the one or more cling coatings and the one or more anchoring sites interact via cohesive forces,wherein the one or more cling coatings comprise a first polymer selected from the group consisting of polyvinyl alcohol homopolymer, polystyrene homopolymer, polystyrene acrylic consisting of styrene and acrylic monomers, and combinations thereof; andwherein the one or more anchoring sites comprise a second polymer, wherein the second polymer is polyvinyl chloride;wherein the one or more cling coatings attach only to the one or more anchoring sites, and do not attach to themselves or other materials, and wherein the first portion and the second portion are on opposite sides of an opening on the resealable packaging, or wherein the first portion and the second portion are each on an outer surface of the packaging and are on opposite sides of the resealable packaging. 2. The resealable packaging of claim 1, comprising a plurality of flaps, wherein at least one flap is aligned with a corresponding second flap on the opposite side of the packaging to form a pair of flaps, and wherein the first portion and the second portion are on opposite flaps of the pair of flaps. 3. The resealable packaging of claim 1, wherein the one or more anchoring sites further comprise a plasticizer. 4. The resealable packaging of claim 3, wherein the plasticizer is selected from the group consisting of diisobutyl adipate, diisodecyl adipate, acetyl tributly citrate, di-isononyl-cyclohaxane-1,2-dicarboxylate, dioctyl terephthalate, epoxidized soybean oil, tri-2-ethylhexyl trimellitate, acetylated monoglycerides of fully hydrogenated castor oil, bis(2-ethylhexyl)-1,4-benzenedicarboxylate, di(2-ethyl hexyl) adipate, di-butyl adipate, butylated hydroxytoluene, hyperbranched poly(ε-caprolactone), di(2-ethylhexyl) phosphate, 2,2,4-trimethyl 1,3-pentanediol diisobutyrate, dioctyl sebacate, and di-butyl sebacate. 5. The resealable packaging of claim 3, wherein the ratio by weight of the polymer to plasticizer for the one or more anchoring ranges from 20:80 to 80:20. 6. The resealable packaging of claim 1, wherein the packaging is food packaging. 7. The resealable packaging of claim 1, wherein the packaging is non-food packaging. 8. The resealable packaging of claim 1, wherein the hardness of the one or more anchoring sites as measured using a Rex durometer model 1000 A ranges from Shore A40-75. 9. A method of sealing a resealable packaging, wherein the resealable packaging comprises a first portion comprising one or more anchoring sites, anda second different portion comprising one or more cling coatings, wherein the one or more cling coatings and the one or more anchoring sites interact via cohesive forces,wherein the one or more cling coatings comprise a first polymer selected from the group consisting of polyvinyl alcohol homopolymer, polystyrene homopolymer, polystyrene acrylic consisting of styrene and acrylic monomers, and combinations thereof; andwherein the one or more anchoring sites comprise a second polymer, wherein the second polymer is polyvinyl chloride, and wherein the first portion and the second portion are on opposite sides of an opening on the resealable packaging, or wherein the first portion and the second portion are each on an outer surface of the packaging and are on opposite sides of the resealable packaging,wherein the method comprises:(a) contacting the one or more cling coatings with the one or more anchoring sites;wherein the one or more cling coatings attach only to the one or more anchoring sites, and do not attach to themselves or other materials. 10. The method of claim 9, wherein the one or more anchoring sites comprise an adhesive to permanently affix one side of the one or more anchoring sites to the packaging. 11. The method of claim 9, wherein the one or more anchoring sites are permanently affixed to the packaging after the packaging is manufactured. 12. The method of claim 9, wherein the one or more anchoring sites are introduced into the packaging during manufacturing of the packaging. 13. The method of claim 9, further comprising (b) separating the one or more cling coatings from the one or more anchoring sites. 14. The method of claim 13, further comprising repeating steps (a) and (b) multiple times.
