Abstract
Packaging material for self-supporting packaging container walls includes two material layers that are fixed at a given spacing from one another. The two material layers define an interjacent chamber which is filled with gas under pressure. The material is produced by the material layers being sealed to one another over a portion of their surface such that a chamber is formed which is filled with, for example, air under pressure.
