I'm making an ink tank for my inkling cosplay, from 3mm Flexible acrylic sheet ([URL="https://www.amazon.co.uk/gp/product/B00MOP69A4/"]This stuff.[/URL])
Anyway, getting it into a tube and keeping it that way is proving... difficult.

So far I've hot-glued it, but it's quite messy looking and I'm not really confident it's going to hold long-term; parts of it are already separating.

Does anyone have any suggestions for a better way to hold it together? (As cheaply as possible, ideally. I don't have much in the way of hardware, or the skills to use it anyway.)

For best results, acrylic cement.

Other types of plastic cements may work, but may not be as strong.
I haven't used this but it might be OK:

Cyanoacrylate (super glue) might work. I haven't tried it. It DID NOT work on clear polycarbonate, but I haven't tried it on acrylic.

In a super pinch, high-temp hot glue will work better than low-temp or multi-temp hot glue, but this is still pretty much a last resort.

Ah! Thank you!

Both of those are astoundingly expensive on the UK site. Is [URL="https://www.amazon.co.uk/Plastic-Cement-Perspex-Acrylic-Styrene/dp/B01I5ORS1Q"]this[/URL] the same thing?

Almost certainly the same thing (or close enough).

Make sure to test on scrap pieces first; it'll be much different than working with hot glue.

You might look for a local plastics supplier or sign shop, who might have it on hand and be able to give you additional advice.

edit, in the "frequently bought together" there was also this:
