| Abstract: |
A reusable, fabric-covered heat exchange bag is provided which includes a thermoplastic waterproof liner means having an interior containment area and an opening for receiving a hot or cold medium, such as hot water or ice. Disposed on a significant portion of the exterior surface of the liner is a thermoplastic fabric-like cover which is joined to the liner to define a peripheral region of the reusable heat exchange bag. The heat seal arrangement which forms the peripheral region of the bag also facilitates the severing of the reusable heat exchange bag from a sheet of stock material.
