A method is provided for hermetic packaging of unimpregnated and impregnated adsorbents which provides for improved packing densities, reduced attrition losses, and reduced exposure of the adsorbent to environmental or other contamination. Furthermore, the method inherently provides for identification of instances of packaging failure. The method entails hermetically sealing a collapsible gas and vapor impermeable vessel containing an adsorbent which is at an elevated temperature. Subsequent cooling of the adsorbent results in the production of a partial vacuum within the vessel. As a result of this partial vacuum, the environmental atmospheric pressure collapses the vessel to firmly compresses the adsorbent in a hermetically sealed low-pressure environment to provide the stated advantages.

[ What is claimed is:] [1.] A method for hermetically packing adsorbents comprising the steps of:(a) hermetically sealing said adsorbent in a gas impermeable hermetically sealable package, said adsorbent being at elevated temperature and(b) hereafter cooling said package to about ambient temperature

[ What is claimed is:] [1.] A method for hermetically packing adsorbents comprising the steps of:(a) hermetically sealing said adsorbent in a gas impermeable hermetically sealable package, said adsorbent being at elevated temperature and(b) hereafter cooling said package to about ambient temperature to provide a reduced pressure within said package by adsorption into said adsorbent, said reduced pressure being reduced below that pressure attainable by cooling said package without said adsorbent.
