ABSTRACT:
A method of opening a bag includes the steps of providing a bag including a first panel, a second panel, a first bag edge, a second bag edge, a bag bottom, and a bag mouth; holding the bag mouth between a first means for vacuumizing and a second means for vacuumizing; moving the first and second means for vacuumizing such that the bag mouth disengages from the tape; activating the first and second means for vacuumizing to draw a vacuum through said means; and further moving the first means for vacuumizing such that the bag mouth opens. In an alternative method, instead of holding the bag mouth with the vacuumizing means, the vacuumizing means can be brought into close proximity to the bag mouth, and activated to draw each panel of the bag mouth to a respective vacuumizing means. Thereafter, both vacuumizing means can be moved upward, and the bag mouth opened. An apparatus for opening a bag is also disclosed.
