<p>An envelope for optical discs consists of a rectangular pattern from which, after folding along the fold line, an envelope is formed. The characteristic feature of the envelope is that at the extension of the front wall (2), or at the extension of the back wall (3) there is a cut (4), which closes the envelope (1). An envelope for optical discs consists of a rectangular pattern from which, after folding along the fold line, an envelope is formed. The characteristic feature of the envelope is that on the open edge of sliding, the optical disc (115) of the envelope (11), behind perforation (16), or crease (1B). There are at least two projections (113) and (113''), that constitute extension of front wall (12) or back wall (13) of the envelope (11).
