Abstract
A storage bag includes an upper layer and a lower layer. The lower layer is bonded to the upper layer. An internal cavity is formed by the layers. An edge is formed by the upper and lower layers. The edge has an opening to provide access to the internal cavity. A spacer is mounted within the internal cavity. The spacer may include at least one channel or cavity that holds liquid in the storage bag when suction is applied to the internal cavity. The spacer provides a structure that prevents the flexible material of the bag layers from moving inward and exerting a pressure on the liquid. The retention of the liquid by the spacer prevents liquid from contaminating the vacuum sealing machine.
