DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a label and to a method of producing labels.
The present invention provides a self-adhesive label comprising a label base portion, which is coated on its rear surface with pressure sensitive adhesive and is carried on a release backing material, a varnish layer which extends over at least a part of the front surface of the label base portion and a label portion which is adhered by a region of adhesive to the front surface of the label base portion, at least a part of the label portion being releasably adhered to the varnish layer.
In one preferred embodiment of the present invention, the label portion is folded and includes a rear part which is fixedly adhered directly to the label base portion and a front part which covers the rear part and is releasably adhered to the varnish layer, the front part being selectively releasable from the varnish layer thereby to reveal the rear part.
The label portion preferably comprises a folded longitudinal strip which is divided into a row of panels by a series of transverse fold lines, an end panel of the strip comprising the said front part and an adjacent panel comprising the said rear part, and a free transverse edge of the front part being releasably adhered to the varnish layer.
Advantageously, the free transverse edge, when released from the varnish layer, retains the adhesive on the rear surface of the free transverse edge whereby the free transverse edge can be subsequently re-adhered to the varnish layer.
In a second preferred embodiment of the present invention, the whole of the rear surface of the label portion is adhered to the varnish layer wherebY the whole of the label portion is releasably adhered to the label base portion.
Preferably, the label portion, when released from the label base portion, retains the adhesive on the rear surface of the label portion whereby the label portion can be adhered to an article.
The present invention also provides a method of producing self-adhesive labels carried on a release backing material, the method comprising the steps of:
(a) providing a support layer coated on its rear surface with a pressure sensitive adhesive and which is carried on a release backing material;
(b) coating at least a part of the front surface of the support layer with a varnish layer;
(c) applying a region of adhesive to the front surface of the support layer, the region of adhesive covering at least a part of the varnish layer; and
(d) applying a face of a label portion to the region of adhesive whereby that part of the label portion which covers the said part of the varnish layer is releasably adhered thereto.
In one preferred embodiment of the present invention, the label portion is folded and includes a rear part which is fixedly adhered directly to an area of the front surface of the support layer which is not coated with the varnish layer and a front part which covers the rear part and is releasably adhered to the varnish layer, the front part being selectively releasable from the varnish layer thereby to reveal the rear part.
The label portion preferably comprises a folded longitudinal strip which is divided into a row of panels by a series of transverse fold lines, an end panel of the strip comprising the said front part and an adjacent panel comprising the said rear part, and a free transverse edge of the front part being releasably adhered to the varnish layer.
In a second preferred embodiment of the present invention, the whole of the rear surface of the label portion is adhered to the varnish layer whereby the whole of the label portion is releasably adhered to the support layer.
The method may further comprise the step, at any stage in the method after step (a), of cutting the support layer into a series of label base portions, and wherein a succession of the label portions is applied to successive regions of adhesive whereby a succesion of self-adhesive labels is produced on the release backing material, each including a respective label portion and a respective label base portion.
