B32B003/00

US Classification:

428195100, 229087190

Abstract:

The disclosure is a gift wrap material affixable to a target surface. The gift wrap material comprises a linerless opaque first substrate. The first substrate has a first major surface and a second major surface. A selective adhesion mechanism is disposed on the first major surface. The selective adhesion mechanism includes a pressure sensitive adhesive and is configured so as to provide a first adhesion force to the target surface before activation of the mechanism and a second adhesion force to the substrate after activation of the mechanism. The first adhesion force is at a level so as to allow the sheet to be positionable on the target surface. The invention also is a method for wrapping a gift. A linerless opaque first substrate is provided. The substrate has a first major surface, a second major surface and a selective adhesion mechanism disposed on the first major surface. The first major surface is positioned against the gift with substantially no adhesion of the first substrate to the gift. The selective adhesion mechanism is activated by applying a force to the second major surface. The first substrate is adhered to the gift.

International Classification:

B32B 7/00

US Classification:

428343000

Abstract:

The inventive pad has a plurality of sheets stacked on top of one another. Each sheet having opposing, writeable first and second surfaces, opposing upper and lower edges, and opposing first and second side edges. A securing mechanism is disposed on the second surface and proximate to the upper edge of the sheet. The securing mechanism includes (a) first and second raised elements and (b) a pressure sensitive adhesive. Each element has an application surface and is aligned generally parallel to and spaced apart from one another. The adhesive has an exposed surface and is disposed between the first and second raised element. The height of the adhesive, as measured from its exposed surface to the second surface is shorter than the height of either raised element, as measure from its application surface to the second surface. The sheets are attached together forming the pad.

Abstract:

A method for making a photographic print having an adhesive is provided. The method includes the steps of (a) providing a roll of dual coated adhesive tape, (b) providing a roll of photographic print having two substantially parallel edges and having opposing first and second surfaces, the first surface containing an image; and (c) laminating the tape and the photographic print. The dual adhesive coated tape includes a differential release liner having opposing first and second surfaces, the first surface having a higher release value than the second surface; a repositionable adhesive disposed on the first side of the liner; a support layer disposed on the repositionable adhesive, the support layer having a stiffness of less than about 50,000 Newton per meter in its cross-web direction, as measured according to ASTM 882-02; and a permanent pressure sensitive adhesive disposed on the support layer.
