CA 2498279

A stand-up reclosable package is formed with a top and bottom seal, and a length-wise seal. The end of the bag is gusseted to form a flat, square shaped surface for the package to stand up. Another seal is formed length-wise along one side of the package to form the sides of the pack, defining the interior volume of the package. The top of the bag may be sealed in a manner consistent with existing vertical form fill and seal technology. The top of the package may have a reclosable feature. Additionally, the present invention provides a method of forming said reclosable stand-up package, including filling the package with desired contents as the package is formed and sealed.

L'invention concerne un emballage refermable vertical qui comporte une soudure supérieure, une soudure inférieure et une soudure longitudinale. L'extrémité du sac comporte des soufflets afin de former une surface carrée plate permettant à l'emballage de tenir verticalement. Une autre soudure, formée dans le sens longitudinal sur un côté de l'emballage pour former les côtés de celui-ci, définit le volume intérieur de l'emballage. Le sommet du sac peut être soudé de manière compatible avec la technologie de remplissage-formage-scellage vertical existante. Le sommet de l'emballage peut comporter une caractéristique refermable. L'invention concerne de plus un procédé permettant de former cet emballage vertical refermable, qui comporte l'étape consistant à remplir l'emballage d'un contenu voulu à mesure que l'emballage est rempli et scellé.
