Abstract:
A method for producing a storable molded body made of bacterial cellulose and a molded body produced according to the method. A preferred method includes providing a molded body made of bacterial cellulose. Optionally, mechanically pressing the entire molded body or parts of the molded body at temperatures in the range of 10° C. to 100° C. and pressures in the range of 0.01 to 1 MPa for a pressing time of 10-200 min. Treating the molded body with a solution of 20% by weight to 50% by weight of glycerol and 50% by weight to 80% by weight of a C1-C3-alcohol/water mixture. Drying the treated molded body.
