Abstract
An easy-open, spiral wound container for packaging refrigerated dough products includes a spirally wound fibrous core layer, forming an unbonded spiral butt joint. The container also includes an inner liner layer and an outer label layer, each having a seam. The outer label layer is weakened along the butt joint to facilitate opening of the container. An end closure member seals an end of the container.
