Pulled a bag of soup out of the freezer last night and put it in the fridge. Just got home a short while ago and pulled it out to heat for dinner. The bag was dripping a bit, and I just figured some moisture on the outside had collected on it. Then I take the bag to the sink so I can transfer the contents into a bowl- and it's dripping pretty good. So I give it a bit of a squeeze- the bloody thing is a sieve! It leaked from at least ten spots, I didn't count. Not from the zipper part, from the material itself.

This happened to the previous bag I pulled out a few days ago as well. So- these cheap bags are leaky. Now I'm wondering how much recycled sewer pipe went into making these bags-:(

My wife has some small glass/pyrex bowls that she uses with cling tape to freeze soup etc. in the frig or freezer. After that its just a trip to the micro-wave and voilla - hot soup to go. She only uses zip-lock etc. bags for solids.

Check the kind of zip locks you have. Some are a permeable plastic for certain foods.

Some plastics don't survive freezing very well and will crack. Were the ones you used specifically for freezing?

I don't think these are permeable- at least there's nothing on the box saying so. It does say freezer bags though.

I've just been playing with one- it's half full of water and is not leaking at all. I've worked it over a bit, and now it's in the freezer. I'll take it out after a couple of days and see if it leaks after being thawed out.

Funny thing with the ones that leaked- it feels like only water coming out, but the stuff inside is gumbo- just about everything I had in the fridge went into it. What is leaking out doesn't look like, or smell like any of the contents. It's almost like the holes are so small that only the thinnest of liquid will seep out.

Maybe they don't like freezing, and micro pores are opening up because of it. I should wash out the last bag and check it out under the electron microscope. Oh, wait- I don't have one :)

As long as the contents aren't exposed to freezer air, I suppose there shouldn't be a health concern. I think I would like to know at what point the pinholes begin to exist- if it's only once the thawing begins it's easy to handle. If it's during the freeze, then it would seem that the contents could become contaminated by the environment in the freezer.

I suppose I should think of the other possibility, that the gunk I made is affecting the plastic. I thought it was all edible stuff I cooked up though- there shouldn't be anything in there that would eat plastic.

At bear camp we all bring soup,pasta,chili,almost anything frozen in 1 gallon freezer bags. We always keep a big water pot on the woodstove & toss in a meal. About an hour it's ready to open & dip out of & eat.We use paper plates & bowls, No muss no pots to clean & so far no leakers.

This summer we were using Ziploc to put fish fillets in and added water to freeze.
Some of those bags had a pin hole in them, five or six out of about twenty bags.

Another thing to consider is if there frozen and get knocked around in the frezer they will get scuff marks on them that will leak.

On one of our 'medium strenuous' hikes, we ended up in an area where there was no water. It was the end of the line for many of us, as far as running out of steam. That was going to be our camp, period, so we thought about how to get enough water to supply our group for the rest of the day and night. There was nothing to carry water in except our bottles, and that wasn't going to be enough. We had passed clear running water about a kilometer back, so all we needed was some containers.

I always carry ziploc bags with me, figuring that I might need a way to keep things dry. I also carry garbage bags- same reason, plus they are good to put garbage in :), and are good to put dirty clothes in to keep them from smelling up the rest of the pack. Anyway, after convincing a few people that a ziploc bag would carry water, a couple of us set out to stock up.

It's pretty hard to carry a bag of water by itself, but if you put them in a garbage bag, you can carry two large freezer bags full in one garbage bag. I should have gone by myself, as then I'd have one in each hand and be somewhat balanced walking the trail. As it was, we each carried one bag of bags of water back to camp and had lots of water for everything.

(non-leaking) ziploc bags to the rescue.

We were just talking about this today- when I go hiking, I like to be prepared (yes I was a boy scout :)) I bring a ziploc bag full of cedar shavings, one with matches, one with a block of wax, one with gloves- all of my dry food is packed in ziplocs, so are my spare batteries, hand warmers, socks, string and cord, etc. You can get several garbage bags into one ziploc too- helps keep the pack compacted.

I initially put the matches and the block of wax into one bag- mistake. It doesn't take long and the striker is no good. The wax is great for helping to start a fire.

Well, the results are in- I can freeze and thaw water in these ziploc bags with no leakage problems. Now I have to assume that some left-over bones in the chicken were the cause of the leaks. I did de-bone as much as I could, but maybe the little bits that were left in the gumbo were kind of expelled outwards when the gumbo froze. If that's the case I just have to cut the bag off and put the contents into a bowl or something to let it thaw. I couldn't feel any protrusions-

The bags do feel greasy on the outside though, as if they sweated out some of the contents. Odd. Maybe a compound in one of the ingredients has reacted with the bag material. Anyone want to come over and have some poly-gumbo? :)

I did a lot of wilderness canoeing/camping when I was younger. I always at least double bagged everything and sometimes triple bagged. There is no way I would trust a single layer to not leak at least odour which is what attracts the bears. It also insures that the foods remain edible if you dump the canoe and have to round up the packs. Of course I always tied the pack to the canoe so they stayed together. In maybe a couple of thousand kliks of canoeing I never dumped. Also never had a bear problem. I practice no-trace camping. In some areas that includes packing out your 5hit too. Triple bag at least. :D

Darryl,
Could it be that the bag of gumbo got bumped around agains the other frozen inhabitants in the freezer after freezing, and the bag got micro bruises and wounds?

The most unusual use of ziplock bags that I have heard of was reported to me by my daughter. She was on a missionary trip to Belize, where they would encounter makeshift bodegas that sold servings of soft drinks. The drinks were not sold in bottles or cups but in a ziplock sandwich or snack bag with a straw sticking out of the end of the zipper.

These bags have not been bumped around at all. I carefully filled them when the gumbo had cooled to something a little warmer than room temp. I checked each bag to be sure that the zip was sealed, then they all went into a plastic tray and into the freezer. The next time they are handled is when I bring one out to thaw- then it's set into a bowl and put in the fridge for a day. I usually need to defrost it a bit more when I pull it out, but I don't want to leave it so long that it's fully thawed.

I've got one thawing right now- that will be my dinner. A lot cheaper than my prime rib/lasagna/chicken pesto soup/pint of beer dinner that I had at the bar last night :).

I don't know what's going on here, but it's not going to stop me from making other large quantities of food and freezing it. What I will do though is place all the bags that I fill into a plastic container WITH LID, and freezing it that way.

I don't know if the freezer has anything to do with it, but I do know that the fan in there runs constantly, and if there's any chance that moisture can be sucked out of anything I put in there, it will be. If I make ice cubes and don't use them for 2 or 3 weeks, they will be gone.

Have I ever mentioned that I hate this fridge-

Don't worry Darryl, the same thing happens for me & my father when we make gumbo or jambalaya. At this point I've accepted that these will seep when thawing. I just set it on a quarter-sheet baking pan to catch everything.

It does remind me of experiments we did in high school with dialysis membranes- it seems to act the same way. Maybe it has something to do with the salt/dissolved goodness concentrations of the Gumbo? I just know that I get very little of this seepage when I bag up my chicken soup.

Might be worth an experiment (as soon as I rearrange the chaos in my freezers, anyhow).

Oh, and I've found that the greasy/oily residue more often than not is just a result of drips or spillage when putting the stuff in the bag.

While the term ziplock is probably being used as a generic term in the above posts, it's also the trademarked name of a particular brand bag. I've found the Hefty brand of bag to have a superior closing mechanism to the Ziplock. I don't know if there's a difference in leakage in the rest of the bag after freezing soup.

This right here is the answer. Anyone who freezes head on shrimp will agree.

Try a tip from the vacuum machine people.....
Line a bowl with some plastic wrap, fill it up with your choice of soup/gombo/stew/etc. and place in freezer. Once it's frozen, remove it from the bowl & put it in the freezer bag or vacuum bag & return it to the freezer.
When it's time to enjoy your "leftovers" simple remove the plastic & place it back in the original bowl that you froze it in, & pop it in the microwave.:)

(I think that I've been a bachelor for too long):D

When I was a younger fellow, I worked in a muffler shop in Los Angeles, Ca.

When things were slow, "Idle hands are the Devil's playground."

We used to take Zip-Lock sandwich bags, drop in a couple of 3/8" bolts, zip the bag almost shut, and add a mix of oxygen & acetylene....Then, seal it up and throw it as high as we could. When it hit the ground, the two bolts would spark against each other, and the gas would go off with a loud bang.
It was like the Fourth of July...until the boss came out and told us to quit wasting acetylene...
Strange, none of us ever found the bolts or the Zip-Lock bags.
