ABSTRACT:
An easy-open container has a spirally-wound bodywall layer, interior barrier liner layer and outer label layer forming an easy-open seam extending spirally between the ends of the container and which is provided with an improved reinforcing and tear strip extending along the easy-open spiral seam. This reinforcing and tear strip is formed by overlapped edge portions of the label layer extending through and out of the spiral seam of the container and being folded-over onto the outside of the bodywall layer and under the label layer. Low strength bonding is provided between the overlapped label layer edge portions and high strength bonding is positioned between the superimposed label layer and folded-over a liner layer edge portion and between the superimposed label layer and bodywall layer for allowing easy starting and stripping of the reinforcing and tear strip along the spiral easy-open seam without the necessity of removing the entire label layer.
