Abstract

A label has a face sheet and below the face sheet a layer of cold flow adhesive. The margin of the face sheet lies outwardly beyond the margin of the cold flow adhesive, thus creating a peripheral region that is initially devoid of cold flow adhesive. Preferably, an undersurface of the face sheet has on it a firm adhesive, to one broad surface of which a polymer film is adhered, the cold flow adhesive being adhered to the other broad surface of the film. The web is formed by applying a strip of transfer adhesive to a release agent on the extended liner, die cutting the adhesive strip to form adhesive patches and an adhesive matrix surrounding the patches; removing the matrix from the liner, then applying an outer strip over the adhesive patches, with the outer strip being formed of the material for the face sheets, die cutting the outer strip around, but outwardly from, the peripheries of the patches to form face sheets and another matrix. The face sheets are ultimately printed.

Claims

1. A label comprising:

a face sheet having an outer surface, an undersurface, and side and end margins, and a layer of cold flow, transfer adhesive located along the undersurface of the face sheet, said adhesive layer being die cut to define side and end margins that are set inwardly, respectively, from the side and end margins of the face sheet, so that the face sheet, beyond said adhesive layer, has a peripheral region that is devoid of said cold flow adhesive, whereby said cold flow adhesive can exude outwardly into the peripheral region, while still remaining behind the face sheet.

2. A label according to claim 1 wherein side and end edges of the adhesive layer are set inwardly from the side and end edges of the face sheet between {fraction (1/64)} and ½

inches.

3. A label according to claim 2 wherein the face sheet is formed from a printable material.
