One or more unique hinges are provided within panels of a fragility packaging article for use in retaining one or more fragile articles within a container (e.g., a corrugated box). The unique hinges provide predicted deformation paths that assist in protecting one or more fragile items stored in the container. One of the unique hinges is a diamond shaped hinge that provides at least two predicted deformation paths. Other unique hinges of the present invention includes a gusset hinge, a step hinge, and a v-hinge, each of which provides at least one predicted deformation path. The predicted deformation paths reduce permanent deformation and provide for improved overall cushioning, thereby increasing protection of fragile items and significantly reducing damage that may occur to the fragile items. The unique hinges of the present invention also improve the cosmetic appearance of a fragility packing article because a majority of crushing occurs along the unique hinges, preventing random unsightly crush points from occurring throughout the packaging article.
