Navy Plastic Binding Coils 4:1 (Box of 100)

Navy plastic binding coils give bound documents a clean, professional finish. These 4:1 pitch plastic spiral coils measure 12 inches long, and each box contains 100 pieces. The navy colour adds a polished look to reports, manuals, presentations, and other bound documents.

Why choose navy plastic binding coils?

Colour can enhance the appearance of a finished document, and navy offers a professional, versatile look. It pairs well with white, cream, light grey, and other light-coloured covers. As a result, it works well for business reports, training manuals, proposals, presentations, and school projects. The colour runs through the plastic, which helps maintain its appearance during regular handling.

Lie-flat binding that lasts

Plastic coil binding lets pages turn a full 360 degrees, allowing documents to lie flat during use. The flexible coil also makes pages easy to turn and helps bound documents stay practical for everyday handling. You can trim and crimp each coil after insertion to create a finished binding that fits the document.

• Sizes 6mm–32mm
• Colour runs through the plastic for a consistent appearance
• Trim and crimp each coil to fit the document

Choosing the right size

Document thickness determines the appropriate coil diameter. The 8mm coil handles roughly 52 sheets of 20 lb bond, while the 14mm coil accommodates about 115 sheets. If a document falls between two sizes, choose the larger coil. This choice allows the pages to turn freely without making the binding too tight.
