Unwanted adhesion between a second panel and a first panel attendant the formation of the sideseam joint is eliminated by providing the second panel with a notch. The notch corresponds in form to the triangular notch or truncated portion at the tapered end of the sideseam forming fifth panel. In this way, when compression of the first panel against the sideseam panel occurs, there is no hot and sticky exposed area of the first panel which will adhere to the second panel.
