Loop wire is a permanent binding choice that creates true lay-flat documents, opened or closed.
There are two types of loop wire: double loop wire and 19-loop wire.
Double loop wire has more loops per inch than 19-loop wire. It creates a fuller-looking bound document edge. Double loop wire comes in 3:1 pitch and 2:1 pitch and uses either square or round hole punching dies.
19-loop wire uses the same rectangular punch pattern as plastic comb binding.
