A flexible container is provided with an improved cover forming a seal over a preformed opening in the container. The container and cover may be made of plastic film or plastic foil. The cover is secured to the bag. One portion of the cover includes a pull tab and also forms a reinforced removable band which is part of the seal. Another portion of the cover forms part of a reinforced collar positioned around the preformed opening, opposite the reinforced band. A tear zone follows a line between the reinforced band and the reinforced collar. To open the container, the removable portion is pulled by the tab, along a line within the tear zone, to separate the seal from the reinforced collar. The collar may be provided with a memory to preferentially close the opening after the container is opened. In some instances, the opening is preformed on the cover and the container wall overlies the opening. A method of making the flexible container is also described.
