I reuse my Vacuum bags for freezing..after turning inside out...scrubbing well in hot soapy water,dipped in a weak sanitizing bleach water, then hung to dry. I think I only use them 2 or 3 times max before tossing.

I try to only use those reused bags for meats...not veggies.

I will reuse the bags with fruit or veggie for veggies or meat...AFTER the cleaning process. I just mark F or V or M on bag I am planning to re-use so I am extra careful.

I have reused Gallon Zipper bags...BUT...I tend to prewrap meat then put them inside a Zipper bag for short term freezing. I only do this when using a vacuum bag for a few days is stupid.

I really hate the smell of those Ziplock freezer bags...so I really don't like to put fresh food in them if I have other choice. Smell the inside of them...and tell me that is a good thing...LOL!

Absolutely reuse them! (After washing well, of course.) The only time I don't reuse bags is if they've had raw meat in them - or sometimes greasy cheese.
