A transportable container for flowable bulk goods is formed by vertically spacing a slip frame former from a bottom support. An outer wrap is disposed around the bottom support and a portion of at least one former wall to initially form the transportable container prior to the addition of the bulk goods into the transportable container. At least one of the slip frame former and the bottom support moves vertically relative to other in response to the fill level of the bulk goods. As the fill level increases in the transportable container, previously disposed portions of outer wrap are disengaged 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. Additional portions of outer wrap are disposed around a portion of the at least one wall of the slip frame former to maintain the transportable container for receiving bulk goods as the previously disposed portions of outer wrap are disengaged from the at least one wall of the slip frame former.
