Are these zip lock or zippers? If they are zippers do they create an air tight seal? Thanks!

these are zip lock. they do not have the zipper runner. they do make a seal good enough to keep clothes "vacuum" packed. That is I don't get any air in once I squeeze all the air out. I have put food in them and when they are too full they will leak.

They are zip lock, not sure what a "zipper" is...seem to be air tight, would not put under water, but keep thing fresh.

J. R., I don't know unless it has to do with the fact that they are Very difficult to open once tightly 'sealed'. Otherwise, they are just 'Mini Ziplock baggies'.

Hmm, I'm not sure. They are plastic with regular zippers sewn in them. I would think some air could get in, and they would not be air tight.

I don't think the're airtight but the ones I have are defective. The "zip strip" is not attatched to both sides of the bag, so they don't seal at all. I have purchased these big zip bags for a few years now and have some old ones here but these are manufactured wrongly.

They stay sealed for a long time. I have used these many times and the seal stays with no problem.

I've already answered these questions!!!! NO zipper doesn't snag. Please don't ask again!!Don't know what material they are and don't care!! THEY WORK IN ALL TEMPERATURES AND CYCLES AND THEY DON"T SHRINK.

Yes, it's possible. They are not air tight seals. Opening and closing is a flap that does not lock onto anything, it just rests on the container.

Yes the lids seem airtight to me. They have screw on grooves that secure on pretty well. Interesting idea to use them for dry snacks. Will have to try.

If a zipper is air tight, then yes. Maybe you want the bags that you use the vacuum cleaner to take the air out and then the package stores flat. Those appear to be air tight.

They are not airtight. Water will not get in. There is no seal, but the lid overlaps the side by 2 inches. The lid also fits very snug. I have used these for about 5 years now. They are very well made (good materials, heavy duty) hold up to lots of abuse and have a lot of space. I put gear I want to keep dry and safe in it and put it in the bed of my truck. I have traveled many thousand miles with these in my truck bed and never had any issues with water leakage no matter what the weather brings.

They work great. You can get all the air out, so there's no chance for frost. It won't be quite as good if you're freezing chunks of things (since it's nearly impossible to get all those air gaps out) or if you're freezing something soft that can get smashed if you seal it too much. Still, it works very well. Much better than regular Ziplock bags. I've reused some of my bags about 3 times, but I'm sure I can get plenty more uses out of them (so long as you're gentle with them and don't accidentally puncture them).

I use these for sewing items fabric and tools etc. Although the lids fit very well I wouldn't say they are airtight. I think they would keep out most bugs. I store some things in my garage. But I wouldn't swear to the kind of vermin and bugs that seem to find their way into just about everything. So far none of my fabrics or tools have had anything in the boxes I didn't put there! If you have something you need to be absolutely airtight against anything. I would recommend a screw on top container. These do though close well and no problems so far. Good luck.

No they are not, The only covering is over just the pull tab when completely closed. The zipper it self is not covered by any flap.

They're not airtight. They're tight enough to stay on when not tossed around or shifted. But, they're definitely not like a Tupperware lid that seals shut.

The bag has a ZIP lock. I squeeze all the air out before closing. I also store it in the fridge. This bag barely lasts a month for a single user.

It really is all about getting a air free seal. As long as I have that I have no problems. I've been using them for years. Also, don't use the bags that are made for another brand. Have never had any luck trying to go cheaper.

I don't know, I got them for work, I can check in a couple of days....Sorry this doesn't help out now, but they are very durable. They get a lot of use at my work and I'm surprised that the zippers are holding up nicely.
