Abstract
A packaging bag for the packaging of articles comprises an envelope made of flexible material containing light weight, energy absorbing, compressible particles in a closed pack relationship, the envelope being sealed into an air tight relationship about said particles and evacuated to an air pressure significantly less than atmospheric pressure such that the particles are maintained in a non-free flowing condition by exterior atmospheric pressure. The bag can then be molded around an article, placed within a container for shipment. Thereafter, the bag can be reused with other articles by restoring its original shape and then molded around the other articles, even if differently shaped, as before.
