Abstract
A cellular cushioning article is described. The cellular cushioning article may be used to wrap items such as fragile items needing protection during storage or shipping. The article includes a polymeric film including discrete first cells projecting from a major surface of the film. The first cells are arranged in rows parallel to each other, such that for two opposing polymeric films with the major surfaces facing each other, the total thickness of the two opposing polymeric films is less than twice the thickness of one polymeric film. The cellular cushioning article can be fan-folded into a stack occupying much less volume as compared to stacks formed by fan-folding known cellular cushioning articles.
