Title (EN) METHOD OF FORMING A BONDED PACKAGE GUSSET
(FR) PROCÉDÉ DE FORMATION D'UN SOUFFLET D'EMBALLAGE CONTRECOLLÉ
Abstract:
(EN) The present invention is directed to a method forming a bottom-gusseted package, wherein each package includes an inwardly-extending, pleat-like gusset at the bottom of the package. To permit heat-sealing formation of each package, the sleeve from which each gusset is formed comprises a lamination of two differing polymeric materials, so that only an exterior surface of each sleeve exhibits the desired heat- sealing characteristics. To facilitate package formation, the sleeves from which the bottom gussets are formed are maintained in a temporarily closed or sealed configuration during package formation by providing a preferably frangible bond or seal at the edge of each sleeve. This result is preferably achieved by folding the laminate material, and temporarily sealing or joining an outer layer of the laminate material from which gusset is formed, while an inner layer is maintained in an unsealed condition.
(FR) L'invention concerne un procédé de formation d'un emballage avec fond à soufflets, chaque emballage comprenant, en son fond, un soufflet plissé qui s'étend vers l'intérieur. Pour assurer la formation de chaque emballage par thermoscellage, le manchon à partir duquel chaque soufflet est formé comprend une stratification de deux matériaux polymères différents, de sorte que seule une surface extérieure de chaque manchon présente les caractéristiques de thermoscellage désirées. Pour faciliter la formation de l'emballage, les manchons à partir desquels les soufflets de fond sont formés sont maintenus dans une configuration temporairement fermée ou scellée, pendant la formation de l'emballage, par la mise en place d'un collage ou joint d'étanchéité de préférence frangible, au niveau du bord de chaque manchon. Ce résultat est de préférence obtenu par pliage du matériau stratifié, et collage ou scellage temporaire d'une couche externe du matériau stratifié à partir duquel le soufflet est formé, pendant qu'une couche interne est maintenue dans un état non scellé.
