An excellent starter pack for those new to using 3:1 (34 loop) spiral with their existing wire binding punching machine.
3:1 Plastic Spiral Multipack includes:
- 20 x 25mm (approx 175 sheets)
- 20 x 35mm (approx 280 sheets)
- 10 x 45mm (approx 390 sheets)
- Total 50 pieces
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 50mm, 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.
We manufacture our plastic spirals on site 24 hours a day from high grade plastic pellets to ensure we produce the very highest quality.

Note: Using the 35mm and larger spirals can be quite difficult and time consuming to roll on, so we recommend splitting your book if at all possible.
