    Abstract: A method of shrinking a heat shrinkable film onto product units, in which a heat shrinkable film is wrapped around a product unit so as to form an opening in the heat shrinkable film on a side of the product unit. A hot, gaseous medium is then emitted from at least one discharge or nozzle to thereby shrink the heat shrinkable film on the product unit while simultaneously moving the product unit on a conveying arrangement along a transport path. The emission of the hot, gaseous medium is controlled such that essentially all of the hot, gaseous medium emitted from the at least one discharge to shrink the heat shrinkable film on the product unit, during movement of the product unit along the transport path, is directed at the side of the product unit having the opening in the heat shrinkable film.

  • Patent number: 8266875
    Abstract: A hot water shrink tunnel includes a heat chamber that has no flue or vent into the heat chamber, an inlet opening and spaced therefrom an outlet opening. Each opening is closed by an end closing device, such as a curtain. A conveyor carries a product through the heat chamber from the inlet opening to the outlet opening. A duct is mounted adjacent each end opening, where the duct includes a shroud of a size and design to capture hot water vapor that issues from the heat chamber when a product passes through the end closing device of the non-flued/unvented tunnel.

  • Patent number: 8234846
    Abstract: A shrink film applying apparatus includes an article feed for feeding articles for shrink-wrapping at line pressure; a wrapping conveyor driven at a wrapping speed through a wrapping zone, the wrapping conveyor receiving articles from the article feed. First and second films are supplied to the wrapping zone. A plurality of flight bars are individually driven in a path at a variable speed. A sealing mechanism within the wrapping zone seals the first film to the second film at contact points to form a circumferential film unit substantially surrounding grouped articles within loops of second film and a corresponding portion of the first film, the film unit being shrinkable about the grouped articles to form a package. Related methods and subassemblies of the apparatus are disclosed.

  • Patent number: 8235712
    Abstract: A device intended to assist in the accurate and controlled shrinkage of thermo-shrinkable container-jacketing material. Said device producing at least an elevated temperature in a heated processing zone. Heat energy available in said heated processing zone primarily derived from a first heat source, preferably pressurized steam. Said first heat source steam exhibiting preferred characteristics related to the controlled shrinking of thermo-shrinkable materials. A second heat source, other than steam, acting in cooperative relationship with said first heat source steam, delaying the decay of one or more preferred characteristics of said first heat source steam. Said first heat source steam, urging said heat-shrinkable materials to shrink, substantially conforming to receiving containers in a preferred manner along one or more axis.

  • Publication number: 20110284558
    Abstract: This invention is to replace the need for a corrugated carton by wrapping an article with a heat shrinkable bubble wrap film. Heat shrinking the bubble wrap will allow the bubble wrap to shrink sufficiently to conform to an article such as a group of containers, e.g. bottles. Because of the inability of the bubble wrap film to tightly shrink around the containers, the containers can move and bump each other.
