ABSTRACT:
A spiral wound can is described which comprises a body layer made of kraft paper or a relatively heavy fiberboard layer lined within by an oil and moisture impermeable barrier formed from a laminate of aluminum foil and paper. The body layer includes a helically extending separation line or butt joint held together by a label and a reinforcing tensile element in strip form. The liner has a peelable or separable adhesive joint between its helically extending edges aligned with and underlying the butt joint so that the butt joint will open as the edges of the liner peel apart after the reinforcing strip is removed. A discrete label covers both the reinforcing strip and the bodystock and is bonded to the bodystock by at least two broken or unbroken bonds of adhesive on opposite sides of the reinforcing strip. A circumferentially extending collar cut is made through the label and reinforcing strip to facilitate their removal. The reinforcing strip is preferably bonded more strongly to the label than to the body and is removed when the label is removed.
