Testing Our Binders

Strongest 3-Ring Binder In The World

strongest 3-ring binders in the world - Naked Binder

Flexed a quarter of a million times and still working...

Hinge strength:

Your average binder will fall apart under moderate use and have to be taped together with in a few months. The cover falls off - which means the hinge has failed. The reason for this is that the strongest part of the binder - the board- does not continue through the hinge. This leaves a small amount of vinyl or a piece of cloth holding your whole binder together. Oops.

The Naked Binder is made from one piece of board. We press the hinge directly into the 110pt binders board that is 100% post consumer waste. This leaves no weak spots on the binder as seen here on the bare board Naked Binder.

This translates to a kind of super binder status. We had an independent laboratory flex these binders 250,000 times with out failing. You can use this binder 20 times a day for the next 34 years and still the hinge will last.

The hinge on a Naked Binder will not fail in regular use. We guarantee it.

Binder strength in the face of water:

Our binders are made from 100% post consumer waste paper board. Will they absorb water? Yes. Will they fall apart? No. How do we know? We are a curious people.

First we left them out in the rain-- for 3 hours and then for two days. They dried out flat and worked fine. So we put them through a dishwasher. Still no problems and still in use. Lets face it, if your binder gets that wet, the papers inside are already ruined, and while it may be a bit warped, you can still use your binder after re-printing everything.

First what are they? We went to the source of all open information - Wikipedia:

Phthalates, or phthalate esters, are esters of phthalic acid and are mainly used as plasticizers (substances added toplastics to increase their flexibility, transparency, durability, and longevity). They are used primarily to soften polyvinyl chloride. Phthalates are being phased out of many products in the United States, Canada, and European Union over health concerns.

What health concerns? Good question. "Children that live in homes with vinyl floors, which can emit phthalates, are more likely to have autism, according to research by Swedish and U.S. scientists published in May 2010." (read the whole thing here)

Vinyl binders, by their very nature contain and give off phthalates. This means the school binders your kids use, the scrapbook binders you collect their pictures in and the wall of binders with your tax information are all releasing phthalates all the time.

What Naked Binder is doing to insure safe products:

Almost everyone at Naked Binder either has children or was a child once (we are pretty sure), and so we were concerned. So we had our binders tested.


No Phthalates detected in tests by method CPSC-CH-C1001-09.2 and U.S. EPA method 827D.

So please, don't use toxic office and schools supplies. It just isn't worth it when better alternatives are right there for you.
