A container having an ethylene vinyl acetate-based or ethylene methyl-acrylate-based sealant as the sealant layer for a flexible membrane lid that is heat-sealed to a ring-shaped metal end on the container. In some embodiments, the sealant comprises ethylene vinyl acetate blended with a polyolefin. The polyolefin can comprise a polyethylene such as low-density polyethylene. The metal end can have a spot-coated surface or an uncoated (i.e., bare metal) surface. A coating of a polypropylene-based composition is provided on the metal end. The sealant layer of the lid is heat-sealed to the polypropylene-based coating on the metal end 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.
