3 mil vs 4 mil vacuum bags

[Beaverdam213]

In the last year I killed a Foodsaver vacuum sealer and one from Cabella’s. I just bought a chamber sealer. I see bags online in different thicknesses. I bought a bunch of 3 mil bags but wondered what you peeps recommend?...

At these thicknesses, each mil (.001") makes a big difference in strength. And the bigger the bag, the more strength you typically need. I'd say .003" is good for up to a couple quarts (at least) and .004" for larger.

I've had failures with the 3 mil bags. Be it material or usage. I don't know. But I use 4 mil bags only now. And the only failures I've had since then was caused by overhandling when I was moving things to the new freezer.
