Abstract
A dough package is described that comprises a fiber can containing dough in which the can wall is composed of a body layer of kraft paper having a helically disposed butt joint defined by its mating side edges to which is releasably bonded a relatively thin lightweight label. The label is releasably bonded to the underlying kraft paper by means of a peelable adhesive layer which functions in one of two ways. In the first, the adhesive functions as a releasable layer interposed between the body layer and the unexposed surface of the label. This layer is released from the label and remains in place when the label is peeled back. In the second method the peelable adhesive layer ruptures or splits as the label is lifted although a small fraction e.g. 10% of the surface kraft fibers may be pulled out when the label is removed. The term 'peelable adhesive' herein refers both to adhesives that split and those that separate from the label when the label is lifted.
