A method of producing a transportable container for flowable bulk goods comprising the steps of: - vertically spacing a slip frame former having at least one former wall defining a frame opening from a bottom support; - dispensing a first portion of outer wrap around the bottom support and around a portion of the at least one former wall to initially form a portion of a transportable container prior to the addition of a plurality of bulk goods to the transportable container; - disposing the plurality of bulk goods into the transportable container through the frame opening to establish a fill level; - vertically moving at least one of the slip frame former and the bottom support relative to the other of the slip frame former and the bottom support to maintain the position of the slip flame former in response to the fill level of bulk goods in the transportable container, as determined by a fill sensor; - as the fill level increases, disengaging previously disposed portions of outer wrap from the slip frame former to squeeze the filled portions of the transportable container and lock together the bulk goods disposed in the transportable container as the at least one of the slip frame former and the bottom support moves relative to the other of the slip frame former and the bottom support; and - disposing additional portions of outer wrap around a portion of the at least one wall of the slip frame former to maintain the transportable container and continue to form the transportable container for receiving bulk goods as previously disposed portions of outer wrap disengage the at least one wall of the slip frame former. - vertically spacing a slip frame former having at least one former wall defining a frame opening from a bottom support; - dispensing a first portion of outer wrap around the bottom support and around a portion of the at least one former wall to initially form a portion of a transportable container prior to the addition of a plurality of bulk goods to the transportable container; - disposing the plurality of bulk goods into the transportable container through the frame opening to establish a fill level; - vertically moving at least one of the slip frame former and the bottom support relative to the other of the slip frame former and the bottom support to maintain the position of the slip flame former in response to the fill level of bulk goods in the transportable container, as determined by a fill sensor; - as the fill level increases, disengaging previously disposed portions of outer wrap from the slip frame former to squeeze the filled portions of the transportable container and lock together the bulk goods disposed in the transportable container as the at least one of the slip frame former and the bottom support moves relative to the other of the slip frame former and the bottom support; and - dispensing a first portion of outer wrap around the bottom support and around a portion of the at least one former wall to initially form a portion of a transportable container prior to the addition of a plurality of bulk goods to the transportable container; - disposing the plurality of bulk goods into the transportable container through the frame opening to establish a fill level; - vertically moving at least one of the slip frame former and the bottom support relative to the other of the slip frame former and the bottom support to maintain the position of the slip flame former in response to the fill level of bulk goods in the transportable container, as determined by a fill sensor; - as the fill level increases, disengaging previously disposed portions of outer wrap from the slip frame former to squeeze the filled portions of the transportable container and lock together the bulk goods disposed in the transportable container as the at least one of the slip frame former and the bottom support moves relative to the other of the slip frame former and the bottom support; and - disposing additional portions of outer wrap around a portion of the at least one wall of the slip frame former to maintain the transportable container and continue to form the transportable container for receiving bulk goods as previously disposed portions of outer wrap disengage the at least one wall of the slip frame former.
