摘要
A method and apparatus for making a structurally resilient package with a desired shape on a vertical form, fill, and seal machine. The method comprises sealing a film to form a back seal; forming a first end seal to form a partially formed first package; flattening a first side of the partially formed first package to form a flat first side; filling the partially formed first package with product; forming a second end seal on the partially formed first package to form a first package from the partially formed first package; flattening the second side of the first package to form a flat second side, wherein the flattening the first side and the flattening the second side occur on a first machine.
