A process to form a generally rigid cushion package from loose fill dunnage material. The loose fill dunnage material is particles of cellular thermoplastic or thermosetting material. The process involves surrounding, within a second packaging enclosure, the article to be packaged with an amount of loose fill dunnage material. The second packaging enclosure is placed in a first packaging enclosure. The second packaging enclosure has an original volume greater than internal volume of the first packaging enclosure. An internal vacuum is created in the second packaging enclosure causing the original volume of material therein to decrease below the internal volume of the first packaging enclosure. The first packaging enclosure is sealed and the vacuum within the second packaging enclosure released.
