Why Polypropylene Ring Binders?

At PFS Design we have been dealing with polypropylene for a number of years now and we use these for ring binders, amongst many others.

Polypropylene is a kind of plastic polymer with numerous applications. It is a key ingredient in both industrial processes and consumer goods such as lunch boxes, toothbrushes, golf balls etc. as a structural plastic or a fibre. It is preferred over normal plastic because it is more durable and more resistant to shattering.

Polypropylene is used to make food containers as it does not melt below 160 degrees centigrade. It is also used for outdoor carpeting as it does not absorb water. It is made from monomer propylene by a process known as polymerization.

Polypropylene ring binders are made from a sheet of polypropylene creased into shape with a ring mechanism riveted in place. Polypropylene is a durable and flexible material available in various thicknesses:

  • 475 micron – lightweight
  • 750 micron – medium weight
  • 1100 micron – heavy weight

The thickest materials are used for larger binders. There are a variety of clear, tints and opaque colours available. They are either screen or litho printed and the print can go right to the edge of the binder but not over the edge.


Polypropylene is a cost effective material with the protective properties of plastic. It will protect contents from spillages and can be wiped clean. Polypropylene is a popular choice for promotional ring binders and can be recycled. Polypropylene ring binders are less rigid than vinyl/paper over board binders, so they will not ‘stand’ on a shelf. The material has a ‘memory’ and once fixed in a position, it will retain that position.

In summary, polypropylene ring binders are:

  • Contemporary
  • Durable
  • Economical
  • 100% recycled available
