Abstract
In producing laminated material for self-adhesive stamps or labels which are stripped from a backing, the backing is coated with a release agent and the adhesive which is dried until it is at least touch dry. Then the perforated face layer of stamps or labels carrying the printing is applied to the backing and the adhesive bonds thereto. By this method, the face layer can be perforated prior to application to the backing and cockling or buckling of the face layer is avoided. This is in contradistinction to the conventional prior methods in which the adhesive is applied to the face layer.
Description
SPECIFICATION
Improvements in manufacture of self-adhesive materials for stamps, labels or the like
DESCRIPTION
This invention relates to improvement in the manufacture of self-adhesive materials for stamps, labels or the like such as tokens, tallies, tickets or markers. For convenience herein, the term stamps or labels will be used as the context permits and is intended to include various forms or applications which arise from the eventual use or printing applied.
Conventional self-adhesive materials comprise sheet or strips of laminated form having a backing coated with a release agent, such as a silicon, and an adhesive intermediate the release agent and a face layer of which the top or outer face is presented for use such as printing. The face layer is usually paper.
Previously it has not been possible to provide lines of weakness in the form of pin-hole perforations or slotted for separation of the individual stamps or labels. This is because it is not possible to use pin-hole perforating or slotting techniques on sheets or strips of conventional laminated materials. This has meant that the lines of weakness have had to be formed by scoring or slitting. In many applications of stamps or labels it is preferred to use lines of weakness such as pin-hole perforations or slots, for instance for postage or revenue stamps. Because this has not been possible, change to self-adhesive materials has been obviated for some traditional uses and applications.
According to the invention, we provide a method of producing laminated material for self-adhesive stamps or labels wherein the backing has a coating of a release agent and a coating of adhesive is applied thereto and, after drying the adhesive coating so as to reduce the water content to an extent that the adhesive coating is at least touch dry, a face layer comprising at least one stamp or label defined by lines of weakness in the form of pin-hole preforations or slots is applied thereto.
By this invention, as the adhesive is dry before bonding, there is no risk of the adhesive flowing through the perforations or slots in the face layer to later interfere with removal from the backing or marking or damaging the printing on the face layer. Additionally, cockling or creasing of the face layer such as arises from laminating onto wet adhesive, is avoided. Thus the face layer can be printed prior to lamination and accurately applied to the backing. This has particular importance for postage or revenue stamps.
This invention permits the use of face layer which is perforated or slotted prior to lamination to the backing, and if desired, the backing can be formed with lines of weakness.
Alignment of the facing layer and the backing can be achieved by providing optical or other registration marks or indices as required.
This has particular advantage in high quality printing for postage and revenue stamps.
Preferably, the facing layer is also provided with a coating on the reverse face to which the adhesive is bonded. Such coating should be substantially impervious and seal the surface of the facing material, usually paper, to ensure that the adhesive bonds thereto. Conveniently such coating on the facing layer can be applied whilst the facing material is in continuous web form and can be sprayed or roller coated thereon. The facing material can then be held or stored for subsequent processing by printing, cutting, perforating, scoring etc. Thus conventional processing can be employed.
It is also preferred that such coating applied to the reverse face of the facing material is soluble in water and coatings of polyvinyl chloride, dextrine, starch or gelatine or blends or mixtures are suitable. By using a water soluble coating, other advantages having particular importance for postage, revenue and other stamps are obtained, as by a simple water treatment, the used stamp can be removed from the carrier leaving behind the adhesive which has secured the stamp to the carrier. For instance, postage stamps can be removed from envelopes, gift tokens from packaging or from labels on jars.
CLAIMS
1. A method of producing laminated material for self-adhesive stamps or labels wherein the backing has a coating of release agent and a coating of adhesive is applied thereto and, after drying the adhesive coating so as to reduce the water content to an extent that the adhesive coating is at least touch dry, a face layer comprising at least one stamp or label defined by lines weakness in the form of pinhole perforations or slots is applied thereto.
2. The method according to claim 1 wherein the front face of the face layer is printed prior to application of the reverse face of the face layer to the backing.
3. The method according to claim 1 or claim 2 wherein lines of weakness are formed in the backing.
4. The method according to claim 2 or claim 3 wherein the reverse face of the face layer is provided with an impervious coating prior to application to the backing.
5. The method according to claim 4 wherein the impervious coating is applied to the reverse face of the face layer whilst the material of the face layer is in continuous web form.
6. The method according to claim 5 wherein the impervious coating is applied by spraying or roller coating.
