Abstract: A bag-type liner is applied interiorly of a container, such as a corrugated carton or box, by inserting an open end of the liner over an open end of the container and thereafter creating a vacuum within the container and liner to simultaneously draw the liner within the container. In a first apparatus embodiment of this invention, the vacuum is created by moving a partially opened bottom of the container over a vacuum opening formed in the platen. In a second apparatus embodiment of this invention, a pair of vacuum plenums are movably mounted adjacent to sides and upper portions of the container to draw the vacuum over and between upper closure flaps connected to the container.
