The invention relates to a process for production of a package which consists substantially of plastic film and has means for opening the package without the aid of a tool. The plastic film (10) is supplied from the roll to a cutting station in which cuts (11) are provided in a cycle adapted to the size of the final package, the width of said cuts being smaller than the width of the plastic film, and said cuts pass completely through the thickness of said plastic film. Sealing cover strips (15) which can also be removed are applied in the region of the cuts which they cover completely in each case. The resultant plastic film is subsequently processed further in a known manner to form the final package. The invention also relates to a package which can be subsequently produced.

L'invention concerne un procédé de production d'un emballage, consistant essentiellement en une pellicule plastique et comportant des éléments permettant de l'ouvrir sans avoir à faire recours à un outil. La pellicule plastique (10) est acheminée depuis le rouleau jusqu'à un poste de coupe où sont pratiquées des découpes (11) à un rythme adapté à la taille de l'emballage final, et dont la largeur est inférieure à celle de la pellicule plastique et qui séparent ladite pellicule plastique sur toute son épaisseur. Des bandes de recouvrement (15) sont appliquées dans la zone des découpes qu'elles recouvrent, de manière étanche, mais amovible. La pellicule plastique ainsi préparée subit ensuite d'autres traitements de manière connue en soi, pour donner lieu à un emballage final. L'invention concerne en outre un emballage pouvant être obtenu selon ledit procédé.
