Shown and described are a packaging machine and a method for producing a packaging unit from a packaging sleeve group comprising a plurality of flat folded, upright packaging sleeves, and an outer packaging. It is provided that the packaging machine comprises at least one conveyer unit for conveying the packaging sleeve group in a conveyor direction perpendicular to the longitudinal extent of the packaging group and at least one outer packaging unit for preparing an outer packaging-shaping sheet material in a base position, and in that, seen in the conveyor direction behind the sheet material in the base position, a sealing unit is provided for sealing of the sheet material enclosed in the packaging sleeve group.

Packaging machine and method for producing a packaging unit as well as a packaging unit made of packaging sleeves and an outer packaging

There is illustrated and described a bundle () comprising packaging sleeves () and an outer packaging (), comprising: a plurality of packaging sleeves () of a composite material, and an outer packaging () which surrounds the packaging sleeves (), wherein each packaging sleeve () has a front side () and a rear side (), wherein the front side () and the rear side () of each packaging sleeve () are separated from each other by means of folding edges (F), along which the packaging sleeve () is folded flat, wherein each packaging sleeve () has two openings which are arranged on opposite sides of the packaging sleeve (), and wherein each packaging sleeve () has a longitudinal seam () which connects two edges of the composite material to form a circumferential packaging sleeve (). In order to enable a space-saving, cost-effective and reliable transport of packaging sleeves (), it is proposed that the outer packaging () be produced from a plastics material film ().

Bundle comprising packaging sleeves and an outer packaging

A method for precursor production includes A) providing a multitude of container precursors, and in each case a) providing a sheet-like composite, having a first longitudinal edge, a further longitudinal edge and, from the first longitudinal edge to the further longitudinal edge: i. a first longitudinal crease, ii. a second longitudinal crease, iii. a third longitudinal crease, and iv. a fourth longitudinal crease. The method includes b) producing a first longitudinal fold characterized by a first internal angle along the first longitudinal crease and a third longitudinal fold characterized by a third internal angle along the third longitudinal crease; c) producing a second longitudinal fold characterized by a second internal angle along the second longitudinal crease and a fourth longitudinal fold characterized by a fourth internal angle along the fourth longitudinal crease; d) contacting and joining the first longitudinal edge to the further longitudinal edge thereby obtaining a longitudinal seam.

Method of producing a packaging enveloping container precursors, especially each for a single dimensionally stable foodstuff container, with folding over of the container precursor

The invention relates in general terms to a device for production of a packaging precursor, wherein the packaging precursor consists to an extent of at least 80% by weight, based on the packaging precursor (), of a sheetlike composite, wherein the sheetlike composite includes:

The invention relates to a container precursor comprising a wall, wherein the wall a) surrounds an interior region, and b) comprises a first wall region and a second wall region; wherein the first wall region comprises a first layer sequence comprising a first wall layer, a second wall layer and a third wall layer as overlying layers from the interior region outwards; wherein, in the first wall region, a second carrier layer is characterised by a smaller layer thickness than a first carrier layer, or a third carrier layer, or both; wherein the second wall region comprises a second layer sequence comprising first wall layer, a second wall layer and a third wall layer as overlying layers from the interior region outwards; wherein, in the second wall region, the second wall layer is connected to the third wall layer; wherein, in the second wall region, the third carrier layer is characterised by a larger layer thickness than the first carrier layer, or the third carrier layer, or both. Further, the invention relates to a process for manufacturing a container precursor, a container precursor obtainable through this process, a closed container, a process for manufacturing a closed container, a closed container obtainable through this process, a use of the aforementioned container precursor, and a further use of the aforementioned container precursor.
