Container precursor, in particular for the manufacture of a food container, from a laminate with a plastic gas and aroma barrier and a peeled edge region, which is partially folded back on itself

A process, comprising, as process steps

• a) Provision of a sheet-like composite, comprising
• i) A composite layer sequence, comprising
• A) a composite carrier layer, and
• B) a composite barrier layer, comprising a barrier plastic for at least 70% by weight relative to the weight of the composite barrier layer,
• ii) an edge region, and
• iii) an inner region, abutting against the edge region;
• b) Reduction of the layer thickness of the composite carrier layer in the edge region;
• c) Creation of a fold in the edge region to obtain a first edge fold region and a further edge fold region,
• wherein the first edge fold region and the further edge fold region abut against each other along the fold;
• d) Bringing the first edge fold region into contact with a first part of the further edge fold region, and
• connecting a further part of the further edge fold region to the inner region;
• e) Creation of a further fold in the inner region to obtain a first composite fold region and a further composite fold region,
• wherein the further composite fold region comprises the edge region;
• and
• f) Connecting the first composite fold region to the first part of the further edge fold region and the further part of the further edge fold region.

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, as overlying layers laid on top of one another from the interior region outwards, a first wall layer, a second wall layer and a third wall layer;
• wherein, in the first wall region the first wall layer is connected to the second wall layer and the second wall layer is connected to the third wall layer;
• wherein the first wall layer, as first wall layer sequence from the interior region outwards, comprises a first barrier layer, comprising a barrier plastic for at least 70% by weight relative to the weight of the first barrier layer, and a first carrier layer;
• wherein the second wall layer, as second wall layer sequence from the interior region outwards, comprises a second carrier layer and a second barrier layer, comprising the barrier plastic for at least 70% by weight relative to the weight of the second barrier layer;
• wherein the third wall layer, as third wall layer sequence from the interior region outwards, comprises a third barrier layer, comprising the barrier plastic for at least 70% by weight relative to the weight of the third barrier layer, and a third carrier layer;
• wherein, in the first wall region, the second carrier layer is characterized by a smaller layer thickness than the first carrier layer, or the third carrier layer, or both;
• wherein the second wall region comprises a second layer sequence, comprising, as overlying layers from the interior region outwards, the first wall layer, the second wall layer, and the third wall layer;
• 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 characterized by a larger layer thickness than the second carrier layer, or the first carrier layer, or both;
• wherein, in the second wall region, the first wall layer is not connected to the second wall layer.
