What is “plasticoil” binding. Plasticoil binding is a plastic spring which is inserted into PUNCHED paper that has a line of punched holes. Ninety-nine percent of the holes are round. Sometimes (only rarely) there are holes that are flat on 2 sides and rounded at the ends.
Plasticoil is one of four styles of binding called “Mechanical binding” that are composed of (IN ORDER of frequency)
- Wire-o binding (also called “double-O”, or twin loop)
- Plasticoil
- Cerlox (Americans call it “comb binding”)
- Spiral wire binding
The fourth process called “spiral wire binding” is the same as “plasticoil” but made of steel. Of the four processes plasticoil has the widest range of colours; over 40! Plasticoil does thicker books. Maximum thickness for “wire-o” is 1 ½”, maximum for cerlox is 2”, maximum for spiral wire is 1 ½”. I’ve seen plasticoil sizes up to 3” thick!

Factors to consider
- When opened flat one side of the book is not lined up with the other side, the pages on one side follow the “spring” upwards or downwards. This is ill ADVISED if there is copy or a picture covering 2 pages
- On occasion the “crimped” or bent ends may “unravel”
