An exemplary method of making packages includes advancing a web of connected bags to a position where an opening of the bag is below an engagement device and opening the engagement device. Additionally, the exemplary method includes blowing the opening of the bag to a partially opened configuration, and reverse indexing the web of connected bags so that a portion of the engagement device is disposed inside of the bag and a portion of the engagement device is disposed outside the bag. Subsequently, the exemplary method includes closing the engagement device so that the engagement device engages the bag and moving the engagement device to a position that causes the opening of the bag to have a rectangular shape.
