The invention relates to a method for producing packaging (18) from paper material (5), in particular paper, cardboard or paperboard, said method comprising the following steps: forming packaging (18) from a blank (19) made of paper material (5), which paper material overlaps at at least one joining site (21); positioning the at least one joining site (21) between a sonotrode (2) and an anvil (3); applying the joining site (21) with a joining force in a joining force direction (6); and making the sonotrode (2) ultrasonically vibrate in order to ultrasonically weld the paper material (5) at the joining site (21), which method is characterised in that the paper material (5) is moistened, preferably on the inner sides of the joining sites (21), before forming the packaging (18) and/or while forming the packaging (18) and/or after forming the packaging (18) and/or during the ultrasonic welding.

A meat tray sized and shaped to support raw meat is provided. The meat tray is composed of a paperboard material. The meat tray may include a generally planar base extending to a sidewall that extends transversely from the planar base to an angled outer transition which forms an outer periphery of a tray cavity. A rim of the meat tray is located at a terminus of the angled outer transition and extends away from the cavity. The rim may include an outer arcuate rim portion that extends and curves away from the outer transition and a planar flange extending from the outer arcuate rim portion and terminates at an edge. The edge faces downwardly with respect to the outer arcuate rim portion.

Systems for producing pressware are provided. In one or more embodiments, a system can include an upper moveable platen, a lower moveable platen, a stationary platen, a punch platen, and one or more forming die assemblies. The upper moveable platen and the punch platen can be disposed above the stationary platen and the lower moveable platen can be disposed below the stationary platen. The upper moveable platen, the punch platen, and the lower moveable platen can be configured to move toward and away from the stationary platen. Each forming die assembly can include a set of upper and lower forming dies. The upper and lower forming dies can be coupled to the upper and lower moveable platens, respectively, and configured to press substrates to form pressware products within passageways extending through the stationary platen.

A paperboard servingware container is provided. This paperboard servingware container may include a bottom panel; a curved transition portion located at the periphery of the bottom of panel. An upwardly extending wall extends from the curved transition portion opposite the bottom panel. An angled peripheral transition located adjacent the upward extending wall opposite the curved transition portion. A ledge portion that extends from the angled peripheral transition opposite the upward extending wall and away from the upward extending wall. A folded over flange portion that is bent downwardly with respect to the ledge portion.

A method of processing a blank for forming a construct includes obtaining the blank, the blank including a flexible material and is for being formed into a construct. The method also includes moving the blank in a downstream direction on a first guide and a second guide, and pressing an interior region of the blank with a shaping apparatus in a direction transverse to the machine direction as the blank moves in the downstream direction and as a peripheral region of the blank is engaged by at least one shaping bracket.

Systems and methods for producing pressware are provided. In one or more embodiments, a method for producing pressware can include producing a pressware product between an upper forming die and a lower forming die contained within a forming die assembly, retracting at least a portion of the upper forming die from the pressware product, and ejecting the pressware product from the lower forming die while feeding a web material between the upper forming die and the lower forming die. The method can also include cutting a segment of the web material to produce a substrate, and pressing the substrate between the upper forming die and the lower forming die to produce another pressware product.

A method for forming a composite structure may include positioning a composite sheet adjacent to a die opening. A portion of the composite sheet may be constrained between a first forming surface and a second forming surface. The first forming surface may be spaced a gap distance from the second forming surface. The gap distance may be substantially equal to or greater than the sheet thickness. The composite sheet may be urged through the die opening and along a third forming surface to form a composite bottom from the composite sheet.

A tray made of cardboard, paperboard or other lightweight foldable sheet material that comprises one or more pockets (8) for receiving product. The tray comprises a top sheet defining one or more top sheet openings for the one or more pockets and a bottom sheet attached to the top sheet that comprises one or more bottom sheet openings that are aligned with the top sheet openings.

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.

A bottle forming unit and method for dry-forming a cellulose bottle from an air-formed cellulose blank structure in a bottle forming unit. The dry-formed cellulose bottle comprises a neck portion, a closed bottom portion, and a mid-portion arranged between the closed bottom portion and the neck portion. The mid-portion is arranged in fluid communication with the neck portion. The dry-formed cellulose blank structure is shaped into a shaped cellulose blank structure, where the shaped cellulose blank structure has a tube-like configuration with an inner surface and an outer surface. A first section of the shaped cellulose blank structure is fed to a first forming mould and a semi-closed bottom portion of the cellulose bottle is formed from the first section in the first forming mould, simultaneously with forming the neck portion of a directly preceding cellulose bottle from the first section in the first forming mould. A following second section of the shaped cellulose blank structure is fed to the first forming mould and the neck portion of the cellulose bottle is formed from the second section in the first forming mould, simultaneously with forming a semi-closed bottom portion of a directly following cellulose bottle from the second section in the first forming mould.
