A thermal insulating liner for a container lid has a top sheet and a bottom sheet spaced by a core. The bottom sheet has an exterior metal foil layer. A side edge-to-side edge transverse cut line extends through the bottom sheet proximate each of two opposed ends of the liner. The liner has reduced thickness end margins extending between each said side edge-to-side edge transverse cut line and each of the opposed ends. A die to make the lid liner has a central well and, proximate each end of the die, an upward step to a land with an inside edge of the step having a ramp surface. A first cutting blade protrudes upwardly from the land and a second cutting blade protrudes upwardly above the land at each end of the die and above the level of the first cutting blade.
