Abstract
A peelable lid structure, particularly for use in the closing of food cans, has a tab which is folded over the center panel and secured in the folded position for processing of can contents and/or handling operations. As the tab is secured, an inexpensive laminate structure which requires little or no aluminum content can be used. Methods of forming the peelable lid structure include exposing a layer of heat sealable material and/or an adhesive layer so that the tab (3) can be folded over and adhered to this layer, for example, by heat sealing.
