Abstract
A bag has wall panels defining a receptacle space and providing a bag mouth arrangement between upper end portions of the wall panels. A tamper evident, and if desired hermetic seal, non-reclosable closure adjacent to a reclosable zipper and located adjacently below upper end portions of the wall panels is accessible to be opened when the zipper is open. The zipper is arranged for intermittent opening and closing of the bag and its opposite ends are sealed into the side edges of the bag. The non-reclosable closure may be a peel seal or a rupturable connection.
