PROBLEM TO BE SOLVED: To provide a backing material hard to debond a flat membrane tissue made of a biologically derived material and enabling the membrane tissue to be held advantageously, and to provide a method for easily and inexpensively storing/transporting, packaging and handling, e.g. drawing out, a membrane tissue thus reinforced with such a backing material while preventing the membrane tissue from breakage or the like without impairing its biological properties with its flat shape retained. SOLUTION: In order to storing/transporting this flat membrane tissue made of a biologically derived material, the membrane tissue is lined with the backing material the peripheral rim of which is provided with a means for seizing the peripheral rim. |
