1. A process for forming a medical device comprising:
approximating a film layer comprising cellulose fibers and a porous layer comprising cellulose fibers; contacting the approximated film layer and porous layer with a solvent suitable for swelling cellulose to join the film layer and porous layer to form the medical device as a multi-layered substrate without the use of an adhesive, wherein the medical device is an implantable hemostat and the film layer is bound to a surface of the porous layer by intertwined cellulose fibers of the film layer and the porous layer.
