Round containers are a special challenge for booklet labels.
The standard booklet label won’t work because it is unable to curve beyond how it was made on press. This happens because the laminate on the top of the booklet is shorter than the materials below it. Since the laminate doesn’t stretch, the booklet bunches when it is made to bend around a sharper curve. Aside from bunching, a standard booklet label on a curve is almost impossible to open.
The solution is what we call our Lam to Liner construction. The Lam to Liner booklet label construction is open on one edge. If you notice in the picture above, the peel open edge lays directly on the liner rather than contacting the right base label. In effect, this style booklet label is open on one side which allows it to have zero stress when being applied. Once applied, it becomes sealed. The Lam to Liner works so well because the seal is formed during the application of the label to the container rather than on press.
This is exactly how we handle label very thin curved surfaces with very thick booklet labels.
