A packaged article is composed of a bulk bag having a top end and a bottom end. Further included is a pallet having a first side and a second side. Also included are an outer bag having a first closed end and a first open end and a heatshrink bag having a second closed end and a second open end. The first closed end of the outer bag is between the bottom end of the bulk bag and the first side of the pallet. The first open end of the outer bag is gathered over the top end of the bulk bag to enclose the bulk bag within the outer bag. The second closed end of the heatshrink bag is proximate to the top end of the bulk bag and the second open end contacts the second side of the pallet.

System for heat shrink sealing open-topped containers wherein the system includes a housing or enclosure wherein a majority of a bulk roll of film material is accessible when the cover is open. The system preferably includes two opposing rollers that are configured to engage the film and cause it to move to a dispensing position. In a preferred aspect, the system includes a movable sealing unit that accommodates use of the lidding system with open ended containers having various sizes and shapes. In a more preferred aspect, the system includes an indicia generating device operable to label sealed containers and a knife that generates a perforation in the film during sealing operations.

The present invention relates to a heat-shrinkable packaging intended for wrapping a series of containers, comprising a lower portion, an upper portion and lateral portions and having a reinforcement strip arranged transversely to the rows of containers, the packaging according to the present invention comprising at least two perforation lines. The present invention also relates to a method for packaging containers by means of a packaging and to a packaging blank.

A device for heating wrapped batches of products and a packaging installation provided with such a heating device, specifically having a manifold of heating elements with lines of orifices and a blocking device for the orifices using a mobile plate having for each line of orifices openings, at least two successive openings having different lengths, to go the direction of movement a) from a position blocking at least a first line of orifices and opening at least a second line of orifices, b) to another position opening the first line of orifices whilst maintaining open the second line of orifices.

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.

The purpose of the present invention is to provide a heat-shrinking apparatus for shrink labels which is capable of uniformly heat shrinking a shrink label covering a portion or the entirety of an article, and which is capable of completing heat shrinking in a state in which water drops are not deposited on the article and the surface of the shrink label. Accordingly, the present invention is provided with: a heat treatment chamber (2) having, provided therein, a steam discharge unit (12) for discharging superheated steam in order to heat shrink a cylindrical label (L) fitted to a container (PC), and a heated air blowing unit (14) for causing deposited water drops to evaporate by blowing heated air on the container (PC) after the cylindrical label (L) has been heat shrlUlk; a superheater (22) which heats steam generated by a steam boiler (20), to generate the superheated steam; a preheating lUlit (27) which uses the surplus steam inside the heat treatment chamber (2) to preheat air used to generate the heated air; a heated-air-generating heat exchanger (15) which uses steam to heat the preheated air to a prescribed temperature; and a condensing heat exchanger (31) for condensing the surplus steam.
