Abstract: A method for producing a cardboard-plastic composite shell (10), in particular an MAP cardboard-plastic composite shell for food products, includes at least the method steps (66, 68, 82, 88) providing a plastic foil (12), pre-forming the plastic foil (12) to form a shell shape (14), providing a cardboard blank (16), and connecting the cardboard blank (16) to the already pre-formed plastic foil (12) in order to form the cardboard-plastic composite shell (10). The cardboard blank (16) provided is not folded or incompletely folded directly before the connection to the pre-formed plastic foil (12). When the cardboard blank (16) is connected to the pre-formed plastic foil (16), the cardboard blank (16) is folded onto the plastic foil (12) by a stamp mechanism (24).

Abstract: A system for forming a pressware product from a web of a roll of material includes a positive mold, a negative mold, a heating element, an actuator, a force sensor, and a control system. The positive mold forms a top surface of the pressware product. The negative mold forms a bottom surface of the pressware product. The heating element is coupled to the positive mold or the negative mold. The actuator shifts the positive mold or the negative mold to cut and form the pressware product in a single stroke. The force sensor detects the forming force applied by the actuator, and the control system directs the actuator to adjust the forming force.

Abstract: A system for forming a pressware product comprises rollers, a scoring tool, a scoring station actuator, a forming tool, and a forming station actuator. The rollers pull the web along a path having an angle. The scoring tool receives the material from the rollers and includes a vertically shiftable scoring punch with an edge that extends about an outline of the pressware product and a striker plate. The scoring station actuator shifts the scoring tool to form a slot in the web. The forming tool receives the scored web and includes a vertically shiftable positive mold assembly and negative mold assembly. The forming station actuator shifts the positive mold assembly to press against the web and form the pressware product.

Abstract: The present invention relates to a container for liquid containing food products, manufactured by press forming of a polymer coated fiber based substrate, said container comprising a bottom portion, a sidewall portion and a top flange portion, wherein said press forming has resulted in the formation a plurality of creases extending in a direction from the bottom portion to the top flange portion and further across the top flange portion. The container comprises an indentation pattern (130, 140, 150, 160, 170, 180, 190a, 190b, 200) formed at a creased inner surface of said sidewall portion and/or at a creased top surface of said top flange portion, said indentation pattern preventing migration of liquid from a liquid containing food product in the container along said creases. The invention relates also to a method for manufacturing such container.

Abstract: An apparatus for forming an upper edge of a paperboard container includes a pocket including a shell having a cavity with a mouth configured to receive the container along an axis such that the rim extends beyond the mouth. A workstation includes a forming member having a first forming surface which is actuatable toward the axis from a retracted position spaced from the rim to an extended position lying adjacent an upper end of the rim, and a forming segment having a second forming surface which is actuatable along the axis and the forming member in response to axial movement thereof such that the second forming surface is positioned spaced from a lower end of the rim. The second forming surface is actuatable along the axis towards the first forming surface to form the rim therebetween.
