The present invention relates to a soluble wound dressing material in a film form which is formed from hyaluronic acid (HA), has a thickness of 10 μm or thicker, and has a dense structure which does not include pores on a surface thereof and therein. The soluble wound dressing material in a film form according to the present invention has a dense structure which does not include pores on a surface thereof and therein to drastically reduce a dissolution rate due to a surface area thereof which is much smaller than a surface area of a conventional wound dressing material. Since the soluble wound dressing material in a film form is slowly dissolved on a surface in contact with an exudation to maintain a high HA concentration condition on a wound surface for a long period of time, an excellent would healing environment is created for the wound surface. Also, the soluble wound dressing material in a film form can be conveniently used by easily cutting the material according to a shape and a size of a wound surface. |
