A4 3:1 Plastic Spirals

The standard 3 holes per inch (3:1) is the pitch used for wire binding. You can now use the same punching machine and holes but use our specially made 3:1 plastic spirals instead of wire. With 3:1 wire binding you are limited 14mm thickness before requiring a larger punched hole. But with our 3:1 plastic spirals you can now bind up to 45mm, extending the function of your current equipment. Ideal for situations where you have punched a book that is thicker than 14mm as you can now use plastic spirals rather than having to reprint.

Because we manufacture our plastic spirals from raw materials we can form and cut any length from 170mm > 940mm avoiding waste and cost. Please Contact Us if you have special binding needs for your publications and our sales team will be happy to provide a customised quote.
