A lid that can be sealed to a container to provide packaging includes an edge with a pull tab which facilitates removal of the lid from the container. The lid and pull tab are injection molded integrally, and the pull tab has the form of a flexible grid-like flap that is bendable to a substantially upright position. The pull tab is formed by a number of spaced, parallel and interconnected bars that extend in a direction substantially at right angles to the direction of pulling of the pull tab.
