No. Just leave one corner of the ziplock seal open, and inhale (carefully *\;-). Doesn’t get it really tight, but good enough to more or less keep things in place.
Use a straw. It will amaze you how much more air you can get out of the bags.
A bus driver taught me that! She did it with her meats. She would take them from their original packages, put them in a zipper bag, put in ketchup, or BBQ sauce and whatever seasoning she wanted before sticking them in the freezer, and when she got to the last inch of the zipper, she would put a straw in and suck the rest of the air out.
I thought it was funny, until I tried it.
So I do that with my travel bags.
