Abstract

The invention relates to a membrane that heals on its own after being damaged mechanically as well as a method for producing said membrane which is used for pneumatic structures featuring an internal operating pressure of 10 mbar to 500 mbar. The inventive membrane is provided with a plastic layer on the pressure side, said plastic layer being interspersed with blisters that have a diameter ranging from 10μ to 200μ.
