Shrinking process for producing solid, transportable and printable containers and a device for carrying out a shrinking process of this type

Abstract

The invention relates to a shrinking process for producing solid, transportable and printable containers by wrapping the articles to be packaged with a film in such a manner as to produce an overlapping section of the film ends on the base area, heating by heat exchange or convection in order to seal the free ends in the area of overlap, and finally heating in a shrinking oven, the container so produced being stabilized by the shrinking process. The method comprises first locally limiting the incoming hot air to the base area of the container to form a peripheral shell in the area of the bottle bottoms, the shape of the container being stabilized thereby, while the container is continuously transported during stabilization and the hot air directed onto the base area of the container in a bundle of discretely distributed gas jets is thereby discharged and guided back after a locally limited heat transfer with the film, and more hot gas is directed laterally against the continuously transported container at an increased lateral blow speed in order to complete the shrinking process. The invention further relates to a device for carrying out the shrinking process.
