It should preferably be a liquid-tight packaging for the protection of food, which have at least one liquid component.
  • the invention relates to a method for the production of a packaging, comprising the following steps: a) providing a packaging jacket of a composite material with at least one layer of paper, paperboard or cardboard, with a bottom sealing surface and with a gable sealing surface, b) providing a bottom element and / or a gable element, c) providing a

  • Packaging can be done in different ways and in different ways
  • Packing coats done are often used, for example, a composite of several thin layers of paper, cardboard or cardboard, plastic or metal, especially aluminum. Such packaging is widely used, especially in the food industry.
  • a first manufacturing step is often to produce a circulating packing jacket from a blank by folding and welding or gluing a seam.
  • the folding of the blank is usually along embossed fold lines, which are summarized together with so-called dummy rows under the generic name Rillinien.
  • the position of the fold lines corresponds to the position of the edges of the packaging to be produced from the packing jacket.
  • a blank is therefore understood to mean a longitudinally and transversely cut sheet which has been cut to length in the transverse direction and defined in terms of its circumference ("sheet-like composite") ready for sale, with a packing coat as salable has to be regarded as finished if, if necessary, it is readily ready to be processed in a filling machine provided for this purpose after removal from an outer packaging intended for the transport of the place of manufacture to the place of use.

Abstract

L'invention concerne une enveloppe d'emballage (10') en matériau composite, destinée à la fabrication d'un emballage (15'). L'enveloppe d'emballage comprend : une surface d'enveloppe (17) comportant une sous-région intérieure (17A) et deux sous-régions extérieures (17B), une surface de scellement inférieure (19) destinée à relier l'enveloppe d'emballage (10') à un élément inférieur (23), une surface de scellement frontale (20) destinée à relier l'enveloppe d'emballage (10') à un élément frontal (24), une jonction longitudinale (11) qui relie deux bords du matériau composite à une enveloppe d'emballage périphérique (10') et deux lignes de pliage factices (18) qui s'étendent à travers la surface d'enveloppe (17). La surface de scellement inférieure (19) et la surface de scellement frontale (20) sont disposées sur des côtés opposés de la surface d'enveloppe (17), et l'enveloppe d'emballage (10') est pliée exclusivement le long des deux lignes de pliage factices (18). Afin de permettre la fabrication d'emballages, en particulier d'emballages en plusieurs parties, ayant une géométrie complexe en matériau composite peu coûteux, selon l'invention l'enveloppe d'emballage (10'), dans la région de la surface d'enveloppe (17), ne comporte aucunes lignes de pliage continues à l'exception des deux lignes de pliage factices (18). L'invention concerne également un emballage (15') réalisé à partir d'une telle enveloppe d'emballage (10') et un procédé de fabrication d'un emballage (15') à partir d'une telle enveloppe d'emballage (10').
