Plastic Sheet – Democratizing Reusable Writing

01/11/2017 at 23:42

Hello guys,

I am working on a project to create a plastic Notebook, there are “Industrial Strudders” that may work for this matter BUT.

What about doing it ourselves and democratizing the blueprints so many people can do it themselves. The need is huge, Billions have limited access to writing and writing is a waste of resources and ends up forgotten most of the time, what about if we do not waste the notebook and digitalize the content.

The objective:

To be able to create a plastic sheet as similar as possible to paper but water resistant and more durable.

1)Thickness matter, paper is the measure ( At least for now)

2) Brightness matters, the plastic type should be be as bright and not as “polished” if that can explain it?.. by this I mean it should be porous, as paper, there are organic plastic bags that would surely look closer to paper.

3) Color matters: It can look like recycled paper, but probably not as recicle plastic full of colors.

Who is in for building this machine all together and sharing the blueprints for the world ?

wow, such an incredible work. if i may give a suggest, may be you can try mix the plastic waste material with paper waste material, make it like paper porridge than press it and wait till dry. i have not try it with plastic waste, but it work with other material like fabric, dry leaves, etc. good luck! 🙂

There are books on the market that are mad from plastic currently. If you can find out what they are being made from you should have a clue as to what kind of materials will hold up to this kind of wear and tear.

Along with the development of plastic notebooks/composition books it would also be prudent to check and see what kinds of writing utensils would work best on the different materials, and how they would affect recycling the products later on. You would want to be sure that the writing implement isn’t contaminating the plastic so as to make it non-recyclable after use.

I think the qualities you would be looking for in a plastic would be: flexible, but with enough strength for not puncture easily or deform when under the pressure of the stylus. A white, satin finish polypropylene for example. It would have the benefit of being moderately chemically resistant meaning that the entire book could be shredded and treated with cleaners to remove certain inks/dyes from its surface when re-recycling.

Good luck in your en-devour!

Thanks a lot for the comments.

I have tested the removable ink from pilot and it works great.
I spent hours yesterday in a huge plastic industry event in mexico city. the CaCo3 concentration have to be very high along with a small concentration of polipropilene (PP as you mentioned), so normal plastic sheets industrial production lines won’t work. I will try with 60% to 70% CaCO3 + 40% to 30% PP and learn what happens, then the sheet pieces for the precious plastic machines must be built 😀

Now it is time to play ourselves.

Thanks and I will keep posting the results.

Hi!! I am in Mexico City and would like to help! Am looking for the local community here in the City to see what I can do. Where are you at?

I’ve tried to iron some plastic bags to get some kind of more rigid material, and the results are quite impressive. The look and feel of the plastic when not very thick, is very similar to paper, yet less easy to cut or to bend.

For me, reusable writing would be the possibility to write on a plastic sheet with some kind of ink and be able to erase it easily using water. recycling a sheet that is 99% clean and ready is, in my opinion a waste of time, resources and energy.

I am keen to see and hold an erasable plastic notebook for drafting, sketching, etc 🙂
