The method of claim 1 wherein the method further comprises the step: a. forming at least one hem seal on the film. 18. The method of claim 17 wherein step a takes place prior to the film being introduced to the first machine. 19. The method of claim 1, wherein the first package comprises: a front face;a back face;a top face and a bottom face connecting the front and back faces;a first side and a second side connecting the front and back faces, wherein the first and second sides are perpendicular to the front and back faces, and wherein the first side comprises the first end seal, and the second side comprises the second end seal;a first upper hem seal located at the approximate intersection of the front face and the top face;a first lower hem seal located at the approximate intersection of the front face and the bottom face. 20. An apparatus comprising an improved vertical form, fill, and seal machine for making a first package with a desired shape, said vertical form, fill, and seal machine comprising a product conduit, a conveyor, bottom gusseters, and seal jaws; wherein the conveyor is positioned to contact a package film that is wrapped around the product conduit; wherein the conveyor moves the package film along the product conduit; wherein the seal jaws are positioned adjacent to opposite sides of the package film to form a first end seal on the package film thereby forming a first side of the first package and thereby forming the first end seal of the first package when the seal jaws move together and the package film is pressed between the seal jaws; wherein the bottom gusseters are positioned to form gussets adjacent to the first end seal of the first package; wherein the product conduit is positioned so that a product passing through the product conduit will enter the first package after exiting the product conduit; wherein the product conduit is positioned above the bottom gusseters; wherein the bottom gusseters are positioned above the seal jaws; and wherein the bottom gusseters are adjacent to a first side of the seal jaws; wherein the improvement comprises: tuckers and top gusseters;wherein the tuckers are configured to move between an engaged position of the tuckers and a disengaged position of the tuckers;wherein, in the engaged position of the tuckers, the tuckers contact the first package and are adjacent to the top gusseters; andwherein in the disengaged position, the tuckers do not contact the first package;wherein the top gusseters each comprise two portions rotatable along an axis of rotation to form a folded configuration and a flat configuration of the top gusseters;wherein, when the top gusseters engage the first package and the top gusseters are in the folded configuration, a first side of the top gusseters presses a second side of the first package against the tuckers;wherein the seal jaws are positioned above the top gusseters, wherein the first side of the top gusseters is adjacent to a second side of the seal jaws, wherein the second side of the seal jaws is opposite the first side of the seal jaws, and wherein a second side of the top gusseters is opposite the first side of the top gusseters. 21.
