ABSTRACT:
A blank which is capable of producing a tube of moisture-resistant material which may be end sealed to form a package. The blank comprises a substratum of card or the like with a delaminable sheeting thereon. The blank has fold lines defining opposable body walls and at least one end closure panel. Flange panels are defined with extensions and allow the formation of a sealable fin. Apparatus and method are provided for side seaming such a blank with outfolding of panels to fuse the sheeting into a tube and delaminate the sheeting from the substratum. Apparatus and method are also provided for end sealing such a tube, with provision for outfolding of gussets and fusion and delamination of the sheeting to provide an end membrane delaminated from the substratum.
