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

The invention relates to a closed container, delimiting an interior from an exterior, wherein the closed container comprises a sheetlike composite; wherein the sheetlike composite comprises a layer sequence, comprising as mutually superposed layers in a direction from an. inner face of the sheetlike composite to an outer face of the sheetlike composite a) an inner polymer layer, b) a barrier layer, and c) a carrier layer; wherein the closed container is characterised by a shaping coefficient, determined according to the method described herein, in the range from 1.0 to 10.0 m/kg. Further, the invention relates to a method by which a closed container with a shaping coefficient is obtainable; to the closed container obtainable by this method; to an apparatus, designed for producing one of the afore&#xac; mentioned closed containers; to a use of a sheetlike composite for producing one of the afore&#xac; mentioned closed containers; and to a use of one of the aforementioned closed containers for storing a foodstuff.

Closed container, in particular a foodstuff container, having a shaping coefficient

The invention relates to a container precursor comprising a sheetlike composite, wherein the sheetlike composite a) comprises a layer sequence comprising, as mutually superposed layers, from an inner face of the sheetlike composite to an outer face of the sheetlike composite, i) an inner polymer layer, ii) a barrier layer, and iii) a carrier layer; b) comprises a first longitudinal edge and a further longitudinal edge, wherein the first longitudinal edge is bonded to the further longitudinal edge forming a longitudinal seam of the container precursor; c) comprises, in the following sequence in the direction from the first longitudinal edge to the further longitudinal edge i) a first longitudinal groove, ii) a second longitudinal groove, iii) a third longitudinal groove, and iv) a fourth longitudinal groove, wherein the container precursor can be shaped to form a jacket structure by folding along the first longitudinal groove, the second longitudinal groove, the third longitudinal groove and the fourth longitudinal groove; wherein the container precursor is characterized by a shaping coefficient as per the test method described herein within a range from 8 to 30 m2/g. The invention further relates to a closed container, to a method, to an apparatus and to the use of the container precursor.
