Patent ID: 7316101

Claim:
A method for sealing an article in a flexible plastic bag of the type having a mating male rib or bead and a female sealing channel closure along the length of the bag opening, comprising the steps of: placing said article into said flexible plastic bag; applying a flowable liquid to the female channel of the bag closure so that it flows into the female channel and becomes generally evenly distributed therein along its length; engaging the rib or bead and female channel together along the length of the opening so as to leave a short portion of the closure unclosed; venting a substantial amount of air from the bag through the unclosed portion of the closure; and thereafter manually applying pinching pressure to the unclosed portion of the closure to engage and close the rib or bead and female channel of the unclosed portion of the closure along its length to seal the bag; whereby the liquid in the channel occupies voids between the surfaces of the engaged mating elements to provide a supplemental seal to increase resistance to air entering the sealed bag.
