The invention provides a flexible package comprising a support member having a flexible film attached to the support member to thereby define a continuous sidewall of the package. The package is movable between a collapsed state for storage and an extended state for use. The support member may comprise an insulating material that substantially limits the amount of heat that may be dissipated through the support member and into the outer surface of the support member. As a result, the support member permits a person to handle the support member portion of the flexible package without burning or discomfort. In addition, the insulated support member may be used to help a heated item disposed in the interior of the flexible package retain its heat. The flexible package may also comprise a support member having fold lines that may extend upwardly from the support member to form a tray-like structure.
