Our plastic coil binding elements are popular for documents that need to lie flat even when opened cover-to-cover. We manufacture plastic coil in a large variety of colors and sizes to suit your needs. Plastic coil is flexible in nature and withstands the wear and tear that comes from rough handling, shipping or mailing.
What is the difference between 4:1 and 5:1 pitch?
Pitch refers to how many holes per inch a binding element uses.
• 4:1 pitch means the plastic coil element has 4 loops per inch.
• 5:1 pitch means the plastic coil element has 5 loops per inch, and the loops are closer together.
