Abstract

"VACUUM PACKAGING APPARATUS AND PROCESS" A vacuum packaging process and apparatus employ the novel step of deliberatety at least partically repressurizing the exterior of a packaging receptacle after commencement of the evacuation of the exterior and interior of the receptacle in a chamber. Two separate gas pressure restroation phases may be employed, separated by a resumption of the gas extraction, and the receptacle is closed during the second of these gas pressure restoration phases.
