A method of producing a transportable container for bulk goods comprising the steps of: placing a bag with an open top and a closed base through a former opening defined by a slip frame former having at least one wall, the slip frame former surrounding a portion of the bag with the closed base being disposed adjacent a bottom support and the open top being vertically spaced from the closed base and disposed adjacent a feed source; filling the bag with bulk goods from the feed source through the open top; disposing a stretch wrap from a stretch wrapping device radially about the bottom support and a portion of the at least one former wall of the slip frame former to initially form a shape of the transportable container; monitoring a fill level of the bulk goods in the bag with a fill sensor while filling the bag; vertically moving at least one of the slip frame former and the bottom support relative to other of the slip frame former and the bottom support in response to the fill level of the bulk goods in the bag to expose the filled portion of the bag there between as the bag is filled with bulk goods, the slip frame former being maintained in a position to surround the fill level of the bulk goods in the bag; disengaging previously disposed portions of stretch wrap from the slip frame former to squeeze the filled portions of the bag and lock together the bulk goods disposed in the bag 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 stretch wrap around a portion of the at least one wall of the slip frame former to maintain the shape of transportable container for receiving bulk goods as previously disposed portions of stretch wrap disengage the at least one wall of the slip frame former. placing a bag with an open top and a closed base through a former opening defined by a slip frame former having at least one wall, the slip frame former surrounding a portion of the bag with the closed base being disposed adjacent a bottom support and the open top being vertically spaced from the closed base and disposed adjacent a feed source; filling the bag with bulk goods from the feed source through the open top; disposing a stretch wrap from a stretch wrapping device radially about the bottom support and a portion of the at least one former wall of the slip frame former to initially form a shape of the transportable container; monitoring a fill level of the bulk goods in the bag with a fill sensor while filling the bag; vertically moving at least one of the slip frame former and the bottom support relative to other of the slip frame former and the bottom support in response to the fill level of the bulk goods in the bag to expose the filled portion of the bag there between as the bag is filled with bulk goods, the slip frame former being maintained in a position to surround the fill level of the bulk goods in the bag; disengaging previously disposed portions of stretch wrap from the slip frame former to squeeze the filled portions of the bag and lock together the bulk goods disposed in the bag 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 stretch wrap around a portion of the at least one wall of the slip frame former to maintain the shape of transportable container for receiving bulk goods as previously disposed portions of stretch wrap disengage the at least one wall of the slip frame former.
