Abstract (en)
[origin: WO2007065385A1] The invention relates to a shrinking process for producing solid, transportable and printable containers, especially bottle containers with a height/width ratio of > 1 and containing heat-sensitive filling substances. The shrinking process comprises the steps of covering the containers to be packaged with a film in such a manner as to produce an overlapping section of the film ends on the bottom surface, heating them by heat transfer or convection, thereby fusing together the free ends in the area of overlap, and then finally heating the containers in a shrinking oven, the container so produced being stabilized by the shrinking process. The incoming hot air is first locally limited to the bottom surface of the container in order to form a peripheral shell in the area of the bottle bottoms and the shape of the container is stabilized while the container is continuously transported during stabilization. The hot air directed onto the bottom area of the container in a bundle of discretely distributed gas jets is discharged and returned after a locally limited heat transfer with the film. More hot gas is directed laterally onto the continuously transported container at an increased lateral blow speed in order to complete the shrinking process.
