Does nobody worry about the foil lining inside the tube affecting the soap? I know a lot of people use Pringles tubes as a soap mould, so I’m guessing it must not be aluminium?

It's covered in a fairly tough, thin plastic film.
I only use pringles tubes for friends to take away soap they've made while visiting, as my recipe takes a couple of days to harden up enough to unmould cleanly and slice.
If it later develops a tiny area of DOS due to a small invisible perforation in the plastic, it's really not a big deal since it's just for fun, though it's not an issue I've encountered yet.
I don't reuse the tubes, which probably helps. The easiest way to get the soap out is to cut down through the first part of the tube, then tear it away from the soap in a spiral pattern.
I knew there was a plastic lining between the inner and the aluminum colored part, but I also lined mine with freezer paper because I wasn't sure if the plastic would melt. I used to use Pringles cans and anything else I could find in the pantry that would produce a log of soap before I got my first log mold.
I also lined mine with freezer paper…..
I line mine with freezer paper too for easier soap removal.
I use parchment paper.
Parchment paper always wrinkled around my final soaps no matter how smoothly it appeared that I had lined my molds. It was baffling and irritating. The problem was solved as soon as I started using freezer paper so I haven't bothered trying to use parchment for soaping since then.

I really don't want to line it if i can get away with it. Besides which - we can't get any of your butcher, parchment or freezer paper here. I usually use baking paper but that won;t work for what I want to do:
Google says it is aluminum foil. The video you attached really doesn’t look like the can is lined, especially when the can is peeled away. Just the ends with some plastic wrap to prevent leakage. 
Here's another round soap video by Etsuko where the Pringles can is clearer (skip to where the soap is being unmolded).
@KiwiMoose if the Pringles cans are the same in NZ as we have here in the US, you don't have to line them. I only do it so I don't have to deal with peeling the can off the soap.
That looks like a fun project
Can you order heat resistant Mylar sheets where you are @KiwiMoose? I have some similar to those in the link above. They are very flexible, but I would cut them with an overlap to force the full circle shape. I can test one in a Pringles can for you when I get home this afternoon and send a pic.
Great idea @ScentimentallyYours, I use this Mylar on the bottom of my silicone mold. It would also work great to line a Pringle’s can. https://a.co/d/gSe1RNk
May I ask why you line the bottom of your silicone mold? Also: Does this material fold? I'm curious to know if this could be used to make a reusable liner for wooden molds, too.
