<p>A peelable lidding structure (1) particularly for use in the closing of food cans has a tab (3) which is folded over the centre panel (4) and secured in the folded position for processing of can contents and/or handling operations. As the tab (3) is secured, an inexpensive laminate structure which requires little or no aluminium content can be used. Methods of forming the lidding structure (1) include exposing a layer of heat sealable material or an adhesive layer so that the tab (3) can be folded over and adhered to this layer, for example by heat sealing. <IMAGE></p> |
