초록 ▼

A package in the form of a recloseable bag includes a bag body including front and back walls, and a profile strip fastener assembly sealingly mounted on the inside surface of the front wall. The profile strip fastener assembly includes a pair of releasably interlocking profile strips, with a secondary, peelable seal provided between the profile strips apart from their mechanically interlocked portions. By this arrangement, enhanced sealing for the package is provided, while abating the stress to which the interlocked portions of the profile strips are subjected during forming and filling of the package. The bag body preferably includes a removable panel substantially aligned with the fastener assembly for gaining access to the assembly, with the removable panel desirably providing tamper-evidence of opening of the package.
