Label center-sealing method, label center-sealing device and center-sealed label

Abstract

The invention discloses a label center-sealing method, a label center-sealing device and a center-sealed label. The label center-sealing method comprises the step that concave-convex embossed patterns are embossed in a non-center-sealing position area on the label before or after the label is center-sealed. Through embossing the concave-convex embossed patterns on the center-sealed label, tension caused by an arch in a center-sealing position after the label is rolled can be offset, thereby avoiding the problem of deformation occurring after the center-sealed label is rolled; as the deformation of the center-sealed label is overcome, blockage of label sleeving can also be overcome, thereby avoiding the label sleeving efficiency from being influenced and improving the product quality after the center-sealed label is sleeved.

Description

technical field [0001] The invention belongs to the technical field of plastic film labels, and in particular relates to a label folding method, a label folding device and a folding label. Background technique [0002] For container bottles, usually the label with folded palms is used to cover the body of the bottle. Therefore, after the printing of this type of label is completed, it is necessary to put hands together so that the label becomes a ring and can be placed on the bottle body (ie sleeve label). Such as figure 1 As shown, the folded palms label 100 has three layers of film at the folded palm position 101, and only two layers at the non-joined palm position. But label usually all will be rolled up after putting hands together, like this, combined figure 2 As shown, after the label is rolled, a curved edge 103 will be arched at the position 101 of the combined palm label 100 on the combined palm label roll 102 because it is thicker than the non-closed palm posit...

Problems solved by technology

But label usually all will be rolled up after putting hands together, like this, combined figure 2 As shown, after the label is rolled, a curved edge 103 will be arched at the position 101 of the combined palm label 100 on the combined palm label roll 102 because it is thicker than the non-closed palm position, which will cause the label to deform, and finally Lead to poor sleeve labeling, affect the efficiency of label sleeves, and even produce waste products
