This paper proposes the study of innovative packages based on a new folding technique namely crumpling. This technique consists in creating a network of complex 3d crease patterns according to a crumpling process that generates random folds from a single flexible sheet. In order to understand the topological and geometric properties of crumpled structures, a hypergraph modelling is proposed. The graph gives a trajectory of the geometric and topological changes of the crumpled structure during the folding process and highlights some fundamental crumpling operational sequences.
