Abstract: A method for creating a vacuum in a storage bag can be used to create a vacuum without the use of an external vacuum source. The vacuum storage bag has a resilient sponge compressible polymeric material mass such as a sheet of sufficient thickness that is an integral part of an internal wall of a storage bag. A vacuum can be produced by compressing the sponge within this sealable bag. When the sponge is an integral part of the internal bag wall, it will not shift nor interfere with a valve or bag closure. A vacuum may be created by compressing the resilient sponge material along with a food product, dry goods, or any other material that is to be stored. This results in forcing the air volume out of the sealable bag. Any residual air not exhausted from bag will be trapped within sponge material when sponge expands.
