METHOD OF VACUUM PACKAGING COMPRESSIBLE MATERIALS AND APPARATUS ABSTRACT A method of vacuum packaging compressible material in a sealed flexible fluid impervious container, such as a poly bag, is disclosed. One or more slits are made in the container and air in the container is withdrawn through the slits. This creates a partial vacuum in the container that results in compression of the compressible material. When the desired compression has been obtained, restraining means are placed around the flexible container to maintain the package in a compressed state when the partial vacuum is eventually lost. A novel apparatus for use in this method is also disclosed.
