Abstract
A paperboard carton is provided with an upper and lower continuous thermoplastic liner adhesively connected in spaced relation to the walls of the carton to form with the walls, a pouch for the contents of the carton. The pouch eliminates the need of a separate foil, glassine, plastic or like receptacle within the interior of the carton to preclude the contents from sifting through the walls and to provide an effective seal once the carton is opened, so as to maintain the carton contents, such as food, fresh.
