An apparatus for heat treatment of a heat shrinkable film includes a steam generation apparatus that generates steam, a heated air generation apparatus that generates heated air not lower in temperature than steam generated in the steam generation apparatus, a mixed gas generator that generates mixed gas not lower in temperature than steam generated in the steam generation apparatus by mixing steam generated in the steam generation apparatus and heated air generated in the heated air generation apparatus, a reheating apparatus that generates superheated steam by reheating mixed gas generated in the mixed gas generator, and a supply portion that supplies superheated steam generated in the reheating apparatus to a heat treatment chamber.

A direct gas-fired process air heater assembly that utilizes a premix burner applied to a shrink wrap conveyor oven for uniform dissemination of heated air into the a recirculating air stream of a circulating blower, said air circulating blower directing the heated air into the shrink wrap chamber or tunnel for shrinking polymer film around packaged goods for shipment and/or storage. According to various aspects, exemplary embodiments are disclosed of the direct gas-fired packaged process air heater assembly construction features including the application of premix burner technology.

Disclosed is a packing system for a slide of an aircraft evacuation system, the packing system having: a rigid packboard having a first side end and a second side end that opposes the first side end; a first valise flap having a first outer end and a first inner end, the first outer end connected to the first side end of the rigid packboard; a second valise flap having a second outer end and a second inner end, the second outer end connected to the second side end of the rigid packboard; and lacing for tying together the first inner end of the first valise flap and the second inner end of the second valise flap, wherein the first valise flap and the second valise flap are formed of a heat shrink material.

A system for labeling a beverage container includes a conveyer structured to receive and transport the beverage container. The beverage container is prefilled with an ingestible content and sealed. The top of the beverage container has a mark that a lid reader uses to determine a orientation position and generate an alignment signal. Can positioning pads use the alignment signal to position the beverage container rotationally until the mark aligns with a reference position. An air blast station may be present to release high pressure air onto an exterior of the beverage container and a sleeve applicator overlay a shrink wrap sleeve around an exterior of the beverage container. A steam tunnel uses steam to cause the shrink wrap sleeve label to shrink onto the beverage container.

A shrink-wrapping arrangement can be used for shrink wrapping containers or packages, including bottles, boxes, cans, or similar containers or packages, and a method of operating a shrink-wrapping arrangement can be used for shrink wrapping containers or packages, including bottles, boxes, cans, or similar containers or packages.

A tray sealer including a sealing station comprising a tool upper part, a clamping frame and a tool lower part. The tool upper part may surround a dome-shaped die used for deforming a skinnable top film. First and second channels in the dome-shaped die and in the tool upper part, respectively, are connectable to one another. The tool upper part or the dome-shaped die may comprise at least a third channel communicating with a vacuum generator so as to generate a thermal air convection from the first channel to the third channel along a side of the top film facing the dome-shaped die.

A packaging apparatus includes a control unit, a loading station that positions a tubular film around a product to be packaged, a sealing station, a control unit that controls the sealing station to create one or more seals on the tubular film, an evacuation assembly that includes a first member and a second member arranged opposite the first member, and a means for moving the product relative to and from the evacuation assembly. The first member includes a deformable portion. The first and second members are relatively movable between: a first configuration, in which the first and second members are spaced apart from one another, a second configuration, in which the deformable portion contacts at least part of the second member and/or part of the tubular film, and a third configuration in which the deformable portion is compressed in a compression direction towards the second member.

A method and apparatus that blows a heated airstream at overhanging portions of overwrapping plastic film to diminish same to without curling a product that is overwrapped by the plastic film. The overhang conforms in shape to a neighboring portion of a product. A conveyor conveys the plastic-overwrapped product to a heating section where the heated airstream is directed onto the overhanging portions of the plastic film.
