An insulating beverage cup or sleeve is produced with a foam layer disposed on an inner surface of a food or beverage paper stock. A polyethylene film layer is arranged in a position between a paper stock layer and an inside surface of the beverage container. The foam layer decreases the energy transfer between the beverage and the user's hands allowing the user to hold onto the cup for an extended period of time without causing user discomfort or pain, e.g. greatly extends the hold time of the paper cup. The exterior surface of the beverage cup remains highly printable and predisposed to high quality graphics both before and after cup manufacture.
