Abstract
A label is used to seal a package and provide an indication that an end edge of the package has been opened, while also allowing resealing of the package end edge. The label comprises a substrate with top and bottom faces and first and second parallel edges, with indicia (such as price per unit weight, weight, and total price indicia) imaged on the top face. A perforation generally bisects the substrate into generally equally-sized first and second portions, the perforation extending generally transverse to the first and second edges. On the bottom face of the first portion is permanent adhesive (e.g., pressure sensitive), while on the bottom face of the second portion is repositional adhesive. To open the package one tears along the perforation line to detach the second portion of the label from the package, and then tears the first label portion at the package end edge. To reseal the end edge, one places the second label portion over the end edge, the repositional adhesive holding it in place.
