Package cushioning for an article to be packaged

Abstract

A cushioning part for cushioning an article to be packaged in an outer packaging has a mat-shaped base layer, from which at least one hollow support body protrudes above a base cross section cutout on the top side. In order to improve the damping of the article to be packaged by the cushioning part, the invention proposes that the support body is designed in the form of an arcuate bridge which spans the base cross section cut out of the support body.
