An insulated shipping container includes a body of foamed polymer material. This body defines a plurality of compartments, an opening from each compartment outwardly to ambient, a transition surface surrounding each opening, and an exterior surface. Preferably, the compartments and exterior surface are both like shapes so that a uniformly thick wall of insulative foamed polymer material is provided between the respective compartments and ambient. A single sheet of plastic is integrally bonded to the foamed polymer body and is configured such that it faces all of each compartment within the body, the transition surface, and a substantial portion of the exterior surface of the container. A machine for constructing an insulated shipping container with plural compartments is disclosed. A heat-sealing apparatus or machine with a table-like upper surface and a cavity surrounded on three sides by a heat-sealing margin and a vacuum source may hold two plastic sheets in place while the sheets are heat-sealed thus creating a plastic bag which is trimmed from the sheets. This plastic bag is configured for use in making an insulated shipping container.
