A package is provided for individual plastic membrane discs (7) which makes it possible to remove the discs one at a time without damage to the discs and without disturbing other discs in the package, comprising, in combination, a spirally wound roll (16) of at least two plies (2, 10) of sheet material having facing surfaces to which the plastic membrane discs do not adhere; and a plurality of individual plastic membrane discs (7) interleaved between and supported upon the sheet material and spaced apart from each other on the sheet material so that the discs can be removed one at a time individually without disturbing adjacent discs. A process is also provided for preparing packages of this type, which comprises distributing the discs in spaced-apart relationship upon a surface to which the discs are not adherent of one ply of sheet material (1); placing a second ply of sheet material (10) having a surface facing the discs to the discs are not adherent atop the first, so that the discs are protectively sandwiched between the sheets; and then spirally rolling up the two plies of sheet material to form a roll package (16) with-the discs sandwiched between the sheets. A protective container (30) for the roll can be provided, with means permitting unrolling the two-ply sandwich a little at a time, sufficient to expose and remove one disc at a time, or more, as required. |
