The present invention is directed to a hemostatic composite structure having a bioabsorbable fabric or non-woven substrate having at least two major oppositely facing surface areas and a continuous non-porous polymer-based film that is laminated on one major surface of said substrate. The bioabsorbable fabric substrate can be an oxidized polysaccharide and/or the non-woven substrate can be made from bioabsorbable, non-cellulosic derived polymers. The continuous non-porous polymer based film can be a bioabsorbable polymer. The present invention also relates to a method for providing hemostasis by applying a composite structure described herein onto a wound site in need of a hemostatic device wherein a major surface of the substrate without the film layer is applied onto the wound site.
