ABSTRACT:
A method of making a package includes the steps of folding a thermoplastic film web along its longitudinal axis to make a centerfolded film web having two plies which define a folded longitudinal edge and an open longitudinal edge; forming the centerfolded film into a tube such that the folded longitudinal edge is in transversely overlapping relationship with the open longitudinal edge, preferably such that the folded longitudinal edge is inside the tube, and the open longitudinal edge is outside the tube; longitudinally sealing the tube; closing a first end of the tube; filling the tube with a product; closing a second end of the tube to define a tube segment; and separating the tube segment to make a package. The film web is optionally printed before being folded to make a centerfolded film web.
