Company Profile.pdf

Introduction to spiral binding:

This thickened nylon coated spiral is stronger and higher end. The binding is convenient to use flat and 360-degree flip; the spiral shape means that half of the book can be folded under the other half, which saves space and prevents misalignment when writing.

The spiral coil binding process is as simple as punching holes in the pages, inserting the coil, cutting and crimping the coil ends to secure the ends. This completes the binding.

If the number of bundles is large, we can choose a threading machine, which is faster, and the ends can also be folded with a bending machine without hurting the hands.

Available in a variety of wire colors. Please email luo@sudidg.com for more information or samples.
