The present invention provides a flexible storage bag comprising at least one sheet of flexible sheet
material assembled to form a semi-enclosed container. The bag has an opening and a closure means
for sealing the opening to convert the semi-enclosed container to a closed container. The closure
means comprises a strip of material forming at least a portion of the periphery of the opening having a
first side facing inwardly toward the opening and a second side facing outwardly of the opening. The
first side exhibits an adhesion peel force after activation by a user which is greater than an adhesion
peel force exhibited prior to activation by a user. In a preferred embodiment, the flexible storage bag
includes at least one auxiliary venting opening located remotely from the primary opening and having
an auxiliary closure means for sealing the auxiliary opening. The auxiliary opening has a periphery,
and the auxiliary closure means comprises a piece of material forming at least a portion of the
periphery and having a first side facing inwardly toward the opening and a second side facing
outwardly of the opening. The first side exhibits an adhesion peel force after activation by a user
which is greater than an adhesion peel force exhibited prior to activation by a user. In another
preferred embodiment, the flexible storage bag is self-supporting with the opening extending in a
direction normal to the opening and a substantially planar bottom extending in a direction substantially
parallel to the opening, such that when the bottom is placed on a horizontal surface the flexible storage
bag is self-supporting and maintains the opening in an upwardly-extending condition. Preferably, the
bag maintains the opening in a substantially open condition.
