A hard case for housing and transporting objects comprises a first shell (2) and a second shell (3), hinge means (4) for connecting said shells (2, 3) and enabling the latter ones to be arranged in a closed configuration (C) or in an open configuration (A), and closing means (5) to lock the shells (2, 3) in the closed configuration (C); the shells (2, 3) include respective main panels (11,12) carried out by thermoforming an interwoven polypropylene sheet comprising a plurality of superimposed layers, each layer having oriented polypropylene fibers therein, the arrangement of said layers being carried out in such a way as to interweave the superimposed fibers, and respective side elements (13, 14) comprising respective interface edges (15, 16) intended to be coupled to each other in the closed configuration (C); the side elements (13, 14) are made of polypropylene by injection molding and are fixed to the main panels (11, 12) so as to carry out respective joining portions (19, 20) in which the injected polypropylene of the side elements (13, 14) and the interwoven polypropylene of the main panels (11, 12) are melted and joined to each other in order to form the shells (2, 3) in a single part and entirely made of polypropylene. |
