Abstract

A method for manufacturing a label laminate. A transparent plastic film having a first side and a second side is introduced. The second side of the transparent plastic film is printed. A release liner including a release surface and single layer of a non-tacky adhesive on the release surface is introduced. The non-tacky adhesive on the release surface is activated so that the non-tacky adhesive becomes tacky. The tacky adhesive is attached on the release surface to the second side of the transparent plastic film.

Claims

1. A method for manufacturing a label laminate, comprising:

introducing into a printer a transparent plastic film having a first side and a second side,

printing the second side of the transparent plastic film,

introducing into the printer a release liner wound on a roll, the release liner having a release surface and which release surface is coated with a single layer of a non-tacky adhesive,

activating in the printer the non-tacky adhesive on the release surface during printing so that the non-tacky adhesive becomes tacky, and

attaching the tacky adhesive on the release surface to the second side of the transparent plastic film by the printer to form a pressure-sensitive label laminate.

2. The method according to claim 1, wherein the adhesive comprises particles which have a hydrophobic core and a hydrophilic shell.

3. The method according to claim 1, wherein the adhesive comprises particles having a hydrophobic core embedded in a hydrophilic matrix.

4. The method according to claim 1, wherein the adhesive comprises side-chain crystallisable polymers.

5. The method according to claim 1, wherein the adhesive comprises a thermoplastic resin, a solid plasticizer and an adhesive agent.
