The present invention is a method and apparatus for quickly, reliably, and inexpensively evacuating air from ordinary re-sealable plastic bags without employing special adapters to interface with vacuum pumps. The system consists of a vacuum pump, an outer re-sealable plastic bag that acts as a flexible vacuum chamber, a vacuum tray that fits inside the outer plastic bag and prevents the outer bag from collapsing onto the vacuum port. Users operate the system by inserting the re-sealable bag to be evacuated inside the outer plastic bag until the seal of the inner bag is in the proper sealing position inside the vacuum tray. The user then seals the outer bag, turns on the vacuum pump and allows the vacuum process to run to completion, during which the re-sealable inner bag is automatically sealed by the device. The user then opens the outer plastic bag and removes the vacuum-packed inner bag.
