Paintball shell material
Question: What exact material are paintball shell's generally made of? I need to write a paper for my materials class and I want to do a little research on prolonging the shelf life of a paintball. I know that a large problem is that they absorb water and swell. I propose that there could be some coating put on the paintball that would prevent this or at least delay it, giving paintballs a longer shelf life. My biggest concern is environmental impact. Can't use plastic shelled paintballs because the plastic isn't biodegradable. Or at least I think it isn't.
Anyway, I was just looking for some material data so I can get started on this. Hopefully someone here knows, or at least knows who I can go ask (Manike).
If you're really intersted I can post the results of my paper after it's finished in a few weeks.
msg tom "AO TOMS WORKSHOP"he makes balls LOL for real im not busting your stones
I know that Tom either still owns, or used to own Perfect circle paintball. I did a quick serch for that username and phrasing, but I didn't find anything. Can you be more specific?

Barring that, maybe some dessicant powder or something. Chalk maybe? I think I need to do some tests.
I think its made from a Polyethylene glycol. Its hardened through different stages of drying after its a coherent sphere.
Polyethylene glycol is the main ingredient in the fill (along with food dye and sometimes wax), not the shell. The shells are typically made with gelatin (like a soft capsule medicine shell).

look on you tube, theres a short vid about how paintballs are made, it might help a little.

Thanks for the link.
