The present invention relates to a protection device (10). The protection device comprises: a sheet (11); and a plurality of longitudinally extending sealing strips (2, 3) provided on the sheet. The opposed sides of each strip (2, 3) are provided with a sealing surface that is complimentary to the other sealing surface of the strip, such that one side of a strip can sealingly engage with the other to form a seal when the protection device (10) is rolled up into a spiral. The plurality of strips (2, 3) are transversely spaced on the sheet (11) such that when the protection device is rolled up, the strips (2, 3) seal against themselves to form a pocket within the rolled sheet that is bound along longitudinal edges by a pair of transversely spaced seals. |
