So they use Vac-U-Clamp bags to do vacuum laminating for wood and fiberglass applications. This is the small thick vinyl bag.
So I applied high density 1/2 weather strip on one of the 8x8 square Pyrex brand casserole dishes. This isn't for any kind of seal, its just a cushion. On the round pie dish I was playing with a bead of silicone, but its ugly and I like the weatherstripping better.
The bag can hold a hard vacuum, and I tapped around on the glass with the wood of a hammer handle to see if it was just waiting to implode, and it tolerates that. Ive done 3 runs with the square dish on a heating pad and it really is easy.
I like this better for sure, your casserole dish is your thin film vacuum chamber, easy as pie.
