2 mil vs. 3 mil thickness?

GeoHawk · Dec 24, 2011

I am looking into starting to ship some coral. I feel that I have done enough research to do it safely, but I have one last question. The place I want to order my supplies from (insulated box, fish bags) only has 2 mil think bags in the size I want. If I double or triple bag, would this be the same as if I had used 3 mil thick bags? Just wanted to get some thoughts.

I don't think it really matters, personally, I think the thicker the bag, the more air that escapes, so 2mil is perfect if you double or triple bag, making sure that you band each bag separately.

Two mil bags I would triple or quadruple. I started doubling 4 mil bags several years ago and no one ever says their bags leaked. Packages get beat around a lot during transit, better safe that sorry. If a bog leaks and gets the heat pack wet the pack stops working immediately.
