A method of forming reinforced packages. The method can comprise moving a blank in a machine direction on a blank conveyor, and forming a tubular web while moving a first web of material and a second web of material in the machine direction. The forming the tubular web can comprise at least partially sealing at least a portion of the first web and the second web together to form a sealed margin of the tubular web. The method further can comprise forming a liner by cutting the tubular web, forming an attached blank by attaching the liner to the blank, and moving the attached blank in the machine direction on the blank conveyor.

The invention relates to a can containing a liquid and/or a gaseous medium which has positive pressure or develops such during transport or storage, wherein the cylindrical can shell of the can consists mainly of paper or cardboard material and is closed at the bottom with a bottom element and at the top with a cover element, wherein the can withstands an internal pressure of at least 5 bar, wherein the innermost layer of the can shell consists of a straight-wound barrier layer having a longitudinally extending folded seam, wherein the barrier layer is a prefabricated laminate made of an inner diffusion-tight barrier film or an inner diffusion-tight barrier laminate and an outer kraft paper layer.

A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.

A can to contain a liquid and/or a gas is closed with a bottom element and a cover element. The innermost layer is a straight-wound barrier layer having a folded seam extending in a longitudinal direction. The barrier layer includes an inner diffusion-tight layer and an outer kraft paper layer. At least two further straight-wound layers made of paper or cardboard are around the barrier layer of the can shell. Adjoining cardboard or paper surfaces of the barrier layer and a next wound layer are adhered directly to each other. Each of the two further wound layers is longitudinally wound and include in the longitudinal direction an overlapping region with itself. The overlapping region of the next wound layer adjoining the barrier layer is offset relative to the folded seam of the barrier layer and the overlapping regions of the two further wound layers are located at different peripheral regions.

A system and method of at least partially forming reinforced packages. The method comprises moving a web of material in a downstream direction through a web forming section, at least partially forming at least a bag portion in the web of material during the moving the web of material through the web forming section, forming an attached web by adhering a construct to the bag portion of the web of material, and moving the attached web through a separating station. The moving the attached web can comprise moving the construct with the web of material. The method further can comprise separating the bag portion from a remainder of the web of material to form a bag during the moving the attached web through the separating station, the bag being attached to the construct.
