A bag having a built-in closure tab is defined. The closure tab is formed from the outer layer of the laminate which makes up the bag. When a user of the bag wishes to close the bag, the user folds or rolls the sides of the bag together down the side of the bag having the tab. The tab is partially separated from the rest of the outer layer of the laminate. A pressure sensitive adhesive disposed on the interior surface of the tab is used to affix the tab to the rolled down portion of the bag, preventing unwanted opening of the bag. The tab may be affixed and removed from the rolled down portion a number of times, thereby allowing the user to open and reseal the bag as many times as desired.

Il est défini un sac intégrant une languette de fermeture. Cette dernière est formée de la couche extérieure du laminé dont est fait le sac. Pour fermer le sac, il faut plier ou enrouler ensemble les côtés du sac jusqu'au bas du côté où se trouve la languette, qui est séparée, en partie, du reste de la couche extérieure du laminé. Un adhésif sensible à la pression, appliqué sur la surface intérieure de la languette, sert à fixer celle-ci sur la portion enroulée au bas du sac, ce qui empêche ce dernier de s'ouvrir par mégarde. La languette peut être assujettie à la portion enroulée et retirée à maintes reprises, si bien que le sac peut être ouvert et refermé aussi souvent que souhaité.
