Adhesive articles, particularly useful as reusable closures, comprising a moisture resistant substrate and a removable adhesive covering at least a portion substrate surface, the adhesive having a Moist Loop Test result of at least about 25 N/25 mm at a test plate temperature of 5° C. The closure may also include a permanent adhesive covering another portion of the substrate surface. The adhesive articles provide easy application to packages and exhibit good adhesion performance in the presence of moisture, such as from refrigerated or frozen food packaging.

The article of claim 1 where the removable adhesive comprises a hot melt pressure sensitive adhesive. 11. The article of claim 1 wherein the removable adhesive comprises a rubber based adhesive. 12. The article of claim 1 wherein the permanent adhesive comprises a rubber based adhesive, an acrylic adhesive, a vinyl ether adhesive, a silicone adhesive, or mixtures of two or more thereof. 13. The article of claim 1 wherein the permanent adhesive comprises an acrylic based or rubber based pressure sensitive adhesive. 14. A sheet of adhesive closures comprising: a carrier sheet having a release surface; and a plurality of adhesive articles releasably adhered to the release surface of the sheet, each article comprising (a) a moisture resistant substrate having a first and second surface, (b) a removable and resealable adhesive adhered to at least a first portion of the first surface of the substrate, and (c) a permanent adhesive adhered to at least a second portion of the first surface of the substrate; wherein the removable adhesive is removable and resealable in the presence of moisture from refrigerated or frozen food packaging environments and has a Moist Loop Test result of at least about 0.8 N/25 mm at a test plate temperature of 5° C. 15. A roll of adhesive closures comprising: a wound carrier having a release surface; and a plurality of adhesive articles releasably adhered to the release surface of wound carrier, each article comprising (a) a moisture resistant substrate having a first and second surface, (b) a removable and resealable adhesive adhered to at least a first portion of the first surface of the substrate, and (c) a permanent adhesive adhered to at least a second portion of the first surface of the substrate; wherein the removable adhesive is removable and resealable in the presence of moisture from refrigerated or frozen food packaging environments and has a Moist Loop Test result of at least about 0.8 N/25 mm at a test plate temperature of 5° C. 16. The adhesive article of claim 1 wherein the removable and resealable adhesive is removable and resealable at temperatures within the range of from about 10° C. to about-30° C. 17. The adhesive article of claim 14 wherein the permanent adhesive comprises a rubber based adhesive, an acrylic adhesive, a vinyl ether adhesive, a silicone adhesive, or mixtures of two or more thereof. 18. The adhesive article of claim 14 wherein the permanent adhesive comprises an acrylic based or rubber based pressure sensitive adhesive. 19. The adhesive article of claim 14 wherein the removable adhesive comprises a UV curable hot melt acrylic adhesive.
