Abstract
A method of opening a bag includes the steps of providing a bag having a first lip and a second lip defining a substantially flat bag opening, the first lip being secured to adhesive strips for positioning the bag and the second lip having an extending portion extending beyond the first lip; and applying a force to the extending portion of the second lip of the bag so as to displace the second lip away from the first lip, thereby opening the bag opening.
