are these more rigid or thicker than usps flat rate mailers?

thicker yes. I think USPS mailer is 200-250GSM. I estimate they are about 300GSM material. I was hoping for 350 myself but they will work for what I need.

what pt material are they made of?

don't think there's an official grade provided by seller but I estimate they are about 300GSM material. I was hoping for 350 but they will work for what I need.

Do you think I could fit an 8x8 canvas board comfortably in these?

The mailers I have open on the long side. They would accomodate your 8x8 canvas board. The mailers are very rigid. I've re-ordered.

Are the kraft ones recyclable?

Hello there! Of course, the are made of 100% recycled fibers, and it's still recyclable. Thank you!
