Heya guys im gonna need a lot of materials to DIY build them myself for a small to medium sized room (unsure measurements yet, gonna move in soon). I'm looking at like minimum 8 inch acoustic panels 14 inch by 8 inch rectangles, at least 6 of these (first reflection points at the sides, and a cloud absorption panel at the ceiling, 2 each). No doubt the acoustic material will be the most expensive so I wana get this out of the way first. I'll probably just wrap them up in breathable fabric and do the wooden plywood frames myself.

To be clear; I just wana know where I can get acoustic materials like Owens Corning or Rockwool (or any other suitable materials for that matter) at wholesale prices since I'm probably gonna need quite a lot to make them into 8 inches (to absorb the low frequencies 100Hz and below).

You don't want rockwool in a breathable fabric in your room. It makes incredibly irritating dust. My parents house has it as roof insulation and I have to wear a mask and gloves to go near it.
You can seal it in plastic and still get the absorption.

Bass will go straight through a thin plastic sheet, like a plastic bag.

Buy Roxul rockwool from hardware store.

If u want thick bass trap, no need to unwrap the plastic packaging. Just double wrap with cheap fabric. Do not choose super thin cloth.

A good idea to keep the fibres in, but won't the fibre be too densely packed, although it would be self supporting?

It's not really self supporting. Every sheet is 2" thick. What you get is like soft mattress. It can't even stand. It's only self supporting when you maintain the original packaging, which is tightly packed.

I thought that is what you meant.
Where did you find this Roxul?
