Abstract
An interchangeable die is disclosed for attachment to a platen of a heat-sealing apparatus for applying seals to containers having an inner sealing surface configured to receive a first lid and an outer sealing surface configured to receive a second lid. The interchangeable die includes a first side defined by a planar first side surface configured to interface with a planar first sealing surface of the platen, a second side disposed opposite the first side and separated from the first side by a first thickness, and a projection extending outward from the second side and having a planar second sealing surface extending parallel to the first side surface and the first sealing surface. The second sealing surface is configured to apply heat and pressure to the inner sealing surface of the container.
