A liner film piece b' of a predetermined shape is punched out from b, a large number of them are separately stored, and each piece is taken out one by one as shown in Fig. 1 [C] and Fig. 2 [A]. The cover film pieces a' were overlapped with each other so that the tab c1 of the cover film pieces a' remained as a seal, and then the cover film pieces a' and the liner film pieces 57 were thermally bonded. When putting the disc into the jacket, fold half of the overlapped liner film piece b' and cover film piece a' in half along the line X-X in Figure 2 [A], and then Fold the tabs c1 and cl and heat seal that part to form a bag, insert a disk (not shown) into the bag, and then fold the last tab c3 to form the bag as shown in Figure 2 [B]. It was heat sealed.
