Abstract: The Padding Element is created by two synthetic foil runs (1, 2) arranged one over the other and which are connected by means of first welding seams (3) and second welding seams (4). In each case two adjacent first welding seams (3) and second welding seams (4) create a chamber which during the manufacturing process of the Padding Element can remain unfilled with air, be partially filled with air, or completely filled with air, as required. In this manner Padding Elements can be produced with configurations individually adaptable to the object to be packed (6). The Padding Element is preferably used for at least three-sided enclosure of the object to be packed (6) and comprises, rather like a book cover, a top cover (7), a back (9) and a bottom cover (8). The Padding Element offers the advantage of requiring little material to create appropriately configured packing elements, with all the corresponding benefits, whereby space-saving disposal after use is effected by slitting open the air-filled chambers. As it is intended to produce the Padding Elements on a Device installed close to their place of use, on an as-required basis, storage space requirements for packing material will be practically negligible.
