Abstract (en)
A container (10) having an ethylene vinyl acetate-based or ethylene methylacrylate-based sealant as the sealant layer (28) for a flexible membrane lid (18) that is heat-sealed to a ring-shaped metal end (16) on the container (10). In some embodiments, the sealant comprises ethylene vinyl acetate blended with a polyolefin. The polyolefin can comprise a polyethylene such as low-density polytheylene. The metal end (16) can have a spot-coated surface or an uncoated (i.e., bare metal) surface. A coating (30) of a polypropylene-based composition is provided on the metal end (16). The sealant layer (28) of the lid is heat-sealed to the polypropylene-based coating on the metal end (16) to form a peelable seal. The resulting seal allows the lid to be peeled off the metal end by detachment of the sealant layer from the polypropylene-based coating. <IMAGE>
