can these pouches withstand a hard freeze or will they burst?

Don't know yet, have not had them that long. The best thing would be to contact Datrex and ask them directly. That would be something they should have tested.

YES, they can. I put a packet in the freezer and held it there for two days, then let it thaw, then repeated the process. No leaks! Important to me because I carry packets in my off road vehicle in freezing temps. I needed confidence that the H2O I kept for just in case would be usable despite several freezing / thawing cycles.

My family of five has one of these three day survival packs in each of their car trunks all year long. None of us has experienced any problems with the water packets bursting. The packets have enough room for expansion.

Happy to answer your questions, Steve. I use them in the freezer all the time but don't drop them! They'll break pretty easily if frozen (especially when filled up with frozen goodies). You didn't ask but I'll offer that I'm very careful when heating something up with these in the microwave. Defrosting, yes; warming, sure; getting something pretty darn hot? I've done it successfully and nothing's melted yet, but I'm cautious.

They have been in my freezer several months. Well made, and I do not think breaking is an issue.

Accidentally answered yes to this. I have never tried freezing with these. Not why I bought them. Sounds a little scary. Would think the glass would easily break.

Yes, IF YOU PURCHASE THE ADAPTERS (sold separately). These pouches are great for storing and freezing. I had only one pouch break and leak on thawing across 9 months of freezing milk (as opposed to many while using other brands with my first).

yes, they freeze very well. I buy them by the case and keep out a few pkgs. and freeze the rest.

Not sure. I did freeze mine but haven't defrosted them yet. I hope they taste alright. I will post when I do defrost them though. They are the same kind that Whole foods and Trader Joe's sell in small containers. They are not that mushy and they were the hit of my party. Everyone loved them!!!

As with freezing any liquid you must leave space for the liquid to become frozen. If you leave enough space for the expansion, no the jar will not break.

I have never used them for freezing food. You can give it a try. they seem spill proof (so far).

Absolutely you can freeze the filled pouches. My friend would make big batches that we would split and freeze. When defrosting you have two options - number one - when traveling you can just let it slowly defrost or defrost in a hot water bath then use the spout to feed baby, option two - at home we would cut the top off of the pouch empty it into a bowl and defrost contents in the microwave. Love this product! (Consider using the spoon attachment when traveling - so convenient)

yes, these are very thick. I use mine to freeze lunch portion left overs. When you accidentally drop one of these plastic containers after it is frozen, it doesn't break like other flimsy ones.

The ones I received are very tough. They are more like a "freezer" strength bag rather than the flimsy sandwich or regular type ziploc bag. I use them for delicate supplements when traveling but have used them for many other items including jewelry.

Yes, though I wouldn't leave them in a freezer as the plastic may become brittle & break.

I would think they would freeze well. I used them fairly quickly, so I didn't have to freeze them. I will tell you they were not all intact when they arrived. It didn't matter for my purposes, but just saying.

Yes, you have to freeze them. They are just like any other Ice pack, but about the size of a slice of bread. There are four in a set, and work well.

I don't know about long term freezing, but the most popular recipe (on the back of the box) calls for a frozen "log" of wafers and whipped cream, and it is all frozen. So, short term, they should be fine. The real problem is that big, thin wafers may break. It doesn't seem to matter, though, since it is only a few.
