The innovative technical trick that creates this impressive compression effect in folders and shelves is a further development of the conventional interlacing of papers with staples. The technique is called "Flat Clinch" - and the principle behind it is, as usual, surprisingly simple in such cases, but totally awesome: In the "flat clinch" method, the staples are flattened under the leaf, so they no longer To grow up. Take a bulging folder out of the shelf and look closely at how - pardon - "violently" the bulging of the clipped document corners contribute to the total volume of the paper. Such unevenly loaded folders also tend to tilt over. The flat-clinch technique also makes them more stable in the truest sense of the word.
But it is not only in the file folder that it unfolds its effect, but also in the storage system in general. The often extensive paper stacks, which are located in document trays, standing collectors or usually simply on the desk, make a much better impression thanks to the flat-stitching. Because the papers lie flat on each other without arching corners. They also do not come so easily to slip, if you want to quickly pull a document out of the middle of the stack. Real and practical work relief, therefore!
