<p>The invention relates to a sealed pliable bag (12), containing loose particles (10) adapted for evacuation by use of a valve (50) or an air tube (48), inserted through the bag and subsequently heat sealed upon withdrawal of the air tube. The particle-filled bag is placed in contact with an article (36) and evacuated so as to conform with the size and shape of at least a portion of the article. Additional particle-filled bags (62, 66) may be positioned over a remaining portion of the article (36). In another embodiment, air may be introduced into the bags, after the bags and article are positioned in a closed container, such as by puncturing or by use of a valve, allowing the bag to expand so as to securely engage the packaged article within the container.</p> |
