Abstract

In order to protect the structural integrity of fragile products during the process of vacuum packaging, a protective cage is used. The protective cage may be constructed using a membrane supported by a suitable frame. In addition, the protective cage may include a suitable mechanism to allow gas to exit the protective cage during the process of vacuum packaging. Further, the protective cage may be adapted to have a variable size, and thus may be adjusted to a desired size. To protect fragile products, the frame and the membrane are such that they, in combination, provide sufficient resistance to compressive forces that might occur during the vacuum packaging process.
