What kind of method is the flexible binding (semi-hardcover binding) mentioned in the MD notebook description?
When looking at the notebook description, one comes across the unfamiliar notation of thread-bound flexible binding. It makes one wonder how it differs in craftsmanship and openability compared to general perfect binding or thick hardcover binding.
It is a method where bundles of paper are stitched and bound with thread and wrapped with a flexible cover, helping it open completely flat at 180 degrees without catching.
Flexible binding is a method of finishing by wrapping a soft cover around the book block stitched with thread instead of thick cardboard. Unlike general perfect binding, which hardens the paper spine only with glue, a thread-bound book moves flexibly at its folded sections, so it does not easily tear apart and opens wide.
MD PAPER PRODUCTS makes notebooks by securing the spines of 16-page folded paper bundles using a traditional thread stitching method[1][2]. Although it takes a lot of manual effort and time to produce, the binding structure remains sturdy, and the notebook opens flat at 180 degrees when opened[3][4]. Because the folded center does not bulge upward, it is convenient to write smoothly without catching[5].
The specific material or thickness of the thread used in the thread binding has not yet been confirmed in official materials.
