ABSTRACT:
Containers are produced from a sheet of flexible material having a thermally bondable inside surface. In one embodiment flaps are formed and folded outwardly to form two windows in the sheet. Pleats are formed and bonded to transverse the windows so that a pleat ply closes the windows. The pleats are folded to bring the flaps against the window closing pleat plies and bonded. In another emobdiment holes are cut in the sheet located in one ply of the pleats.
