US retail source for polypropylene sheets?

Factual Questions
1

I have a bunch of project ideas that would be perfect for thin, flexible polypropylene sheets of the sort used for folding dishes, cool origami, lamps, and DIY bellows.

I can buy some three ring binders and chop them up, but ideally I’d like some larger uncreased sheets, like 18 x 24" or larger - without having to buy 20,000 square feet from an industrial supplier. Why is my Google-fu failing me? I’m in the midwest US FWIW.

McMaster-Carr has some here.

Thanks for this; it looks like the largest sheets I can get in the thickness I want would be 12 x 12", in black - that will work for some of my project ideas. I’d still be interested if anyone has a source for larger sheets or sheets in other colors.

Contact your local plastics house - all big cities have one or more. They will be able to source large sheets.

24" x 100’ won’t work? Too much?

That’s a lot more than I need.

OK - I found a local plastics fabricator who could order a 4x8’ sheet of 0.03" polypropylene, but his supplier didn’t have any thinner stock, like the 200 or 300 micron I was hoping for. Any other ideas? Maybe sign printers or something like that?

See if these guys have local distribution, or will sell to you direct. They have 10 mil thick Polypro.

Here’s another.
