A composite package for warm food items, and the like, in which a moisutre permeable flexible liner is laminated to a relatively rigid vented container base. Vent openings are provided by openings in the panels of the base, or by the open top of the base, all of which are enclosed by the liner. The liner is preferably treated to be impermeable to grease. Permeability of the liner to moisture allows moisture to escape from the interior of the package, while the liner prevents air circulation within the package and thereby keeps the contents from rapidly cooling.
