Im täglichen Leben ist es häufig erforderlich, beschriebene oder bedruckte Papierblätter, Bilder, Kunststoffolien oder dergleichen geschützt aufzubewahren. Als zweckmäßig hat es sich dabei erwiesen, ein Blatt oder kleine Gruppen von Blättern mit sinn- oder sachverwandtem Inhalt in eine ebene Schutzhülle einzulegen. Die Schutzhülle weist ein rechteckiges Deckblatt und ein rechteckiges Hinterblatt auf, wobei das Deckblatt und das Hinterblatt flexible Folien sind. Das Deckblatt und das Hinterblatt sind entlang von zwei der Blattränder miteinander verbunden; so daß die Hülle entlang von zwei der Blattränder offen ist, und die miteinander verbundenen Blattränder in der Hüllenebene Liegen.In everyday life it is often necessary written or printed sheets of paper, pictures, plastic films or the like to be protected. As It has proven to be useful, a leaf or small Groups of sheets with meaningful or related content in insert a flat protective cover. The protective cover shows rectangular cover sheet and a rectangular back sheet on, the cover sheet and the back sheet are flexible foils. The cover sheet and the back sheet are along two of the Leaf margins joined together; so that the shell along two of the leaf margins is open, and the connected Sheet margins lying in the cover plane.

Auch sind ebene Schutzhüllen bekannt, bei denen das Deckblatt und das Hinterblatt entlang von drei der Blattränder miteinander verbunden sind, so daß die Hülle entlang von einem der Blattränder offen ist.Flat protective covers are also known, in which the Cover sheet and the back sheet along three of the sheet margins are interconnected so that the shell along one the leaf margins are open.

Die Deckblätter vieler ebener Schutzhüllen sind transparent, so daß der Betrachter das zu oberst eingelegte Blatt durch das Deckblatt hindurch sehen kann. Eine solche ebene Schutzhülle, deren Deckblatt transparent ist, wird im folgenden als ebene Klarsichthülle bezeichnet.The covers of many flat protective covers are transparent so that the viewer can put the top one Sheet can see through the cover sheet. Such Flat protective cover, the cover sheet is transparent, is in the hereinafter referred to as a flat transparent cover.
