A flexible package is provided having a side panel with an inner surface that is fixedly sealed to the inner surface of a second side panel. A pressure-sensitive adhesive is disposed between the sealable material of one side panel and the outer ply or layer of the side panel. A separation line is provided within the sealable material adjacent the fixed seal. The sealable material from the first side panel separates from the pressure-sensitive adhesive upon application of an opening force transverse to the fixed seal. The sealable material from the first panel remains sealed to the sealable material on the opposing surface of the second panel upon release. The release of the sealable material from its associated panel causes exposure of the pressure-sensitive adhesive. The exposed pressure-sensitive adhesive forms a reclosable seal for the ends of the first and second panels.

La présente invention concerne un emballage souple, comportant un panneau latéral avec une surface interne scellée de manière fixe sur la surface interne d'un second panneau latéral. Un adhésif de contact est disposé entre le matériau scellable d'un panneau latéral et le pli ou la couche externe du panneau latéral. Une ligne de séparation est pourvue dans le matériau scellable à proximité du scellement fixe. Le matériau scellable provenant du premier panneau latéral se sépare de l'adhésif de contact sur application d'une force d'ouverture transverse au scellement fixe. Le matériau scellable provenant du premier panneau reste scellé avec le matériau scellable sur la surface opposée du second panneau, sur libération. La libération du matériau scellable de son panneau associé provoque l'exposition de l'adhésif de contact. L'adhésif de contact exposé forme un scellement refermable pour les extrémités des premier et second panneaux.
