Plastic Coil Binding
Create an impressive presentation with colorful plastic coil bound books.. Plastic Coil adds energy to your reports and proposals, and demands attention. Plastic Coil is perfect for mailers since the spine always keeps its shape with bounce-back flexibility. It lets pages lie flat with 360° rotation for convenient note taking and photocopying. And, it permanently binds, so you can be sure documents stay organized. 4:1 pitch means the binding machine punches 4 round or oval holes per inch, for a total of 44 holes on an 11 inch binding spine. 4:1 pitch generally binds from 30-265 sheets of 20lb. paper. 4:1 pitch binding coil requires a 4:1 pitch binding machine that punches round or oval holes and turns the coils through the holes by use of a manual, semi-automatic, or fully automated inserter.
