Dry Ice Packs for Shipping & Coolers - Shipping Cold Pack Dry Ice for Shipping Frozen Food - Reusable Cooler Ice Pack - Freezer Cold Packs Keep Food Fresh Beverage Cold - 10 Large Sheets

WE 4LIFE DRY ICE PACKS are a major improvement over ice cubes and plastic ice packs. Included are 10 sheets [each about 6" x 14"]. Each sheet consists of 12 attached, but separate cubes; they can be cut by scissors into smaller combinations of cubes or individual cubes; each cube is larger than a traditional ice cube. A frozen sheet has limited bending capability. The process is simple enough; I submerged 2 paper thin sheets in my sink water for under 5 minutes and watched them expand to large cubes. I then patted them dry, lay them flat on top of one another in my freezer and left them to freeze for at least the recommended 8 hours. Well before that, they appeared to be frozen. I placed 1 sheet at the bottom of a 12 liter insulated cooler, put a bottle of water and a can of beer above it and then placed the other frozen sheet above the drinks. The cooler was kept in a temperature range of 60-70 degrees and out of direct sunlight. The next day I repeated the process, but only used 1 frozen sheet, above my drinks. On each day the sheets remained frozen for about 12 hours and, they remained cold for some time thereafter. That's far better than the freeze time provided by the older methods. The frozen dry ice sheets are about as heavy as those alternatives. The sheets appear to be capable of repeated usage. The other major improvement is that there's no worry about ice turning into water [or plastic sweating alot of water] and soaking the contents and the cooler. Although it's advertised that the sheets remain dry, I detected very small slivers of ice on the "fabric" side when removed from the freezer. That caused tiny droplets of water when I allowed the sheets to totally melt in the cooler. The cooler remained mostly dry and, if the sheets had been taken out of the cooler while still frozen, there'd have been no droplets. Once melted, the sheets remain inflated and may be placed back in the freezer to freeze overnight. I noticed no rips or holes on either side of the sheets and cannot explain how or why the tiny ice slivers appeared on the frozen sheets; I thoroughly patted down the sheets prior to initially placing them in the freezer. In any event, this is not a concern for me, as these dry ice powder sheets are such an improvement over the older methods, both in terms of keeping contents dry and in keeping contents cold.

We initially bought these packs when we were moving, thinking we were going to be without a refrigerator for a few days. That didn't turn out to be the case, so I had them around for a while without using them. I decided to give them a try today. I soaked one of the panels in water for a couple of minutes (the instructions said it only had to be a few seconds), then froze them over night. I was able to pack three sections of one pad into my small lunch box. It kept a sandwich, some stuffed cherry peppers, and an apple cold throughout the day. There wasn't any mess (though when I cut the panels down, I accidentally pierced the chamber with the gel in it, so it was one-and-done. There definitely was one side that was colder than the other, and by the end of the workday, it had started to lose its chill. All in all, I don't know that it was much different than the plastic ice packs I normally use.

This is the first time I’ve used inflatable dry ice packs, and I love them! I was drawn to purchasing because of the ease of folding them and storing flat in cabinet. We frequently use ice packs (the large plastic bulky kind) when going back & forth to our beach cabin, and they take up a lot of room in our limited freezer space. These however come flat and can be cut to size you need to fit around your food or to accommodate the size freezer chest you’re using. Each ice sheet is about 17 inches long, and you get 10 sheets . . . so lots of packets if you need to cut them into smaller sizes. I put several packets in a basin of water and videotaped the process so that you can see how fast they inflate. After inflating them, you put in freezer overnight. Easy to use, and they keep food frozen solid. The only thing I'm unsure of is how long the fabric-like covering on the packets will last, especially if heavy frozen food falls against them.

These work well; They're not as durable as hard plastic/ traditional ice packs, but they definitely have some benefits... they stay frozen longer, you can cut them to different sizes. I'm not sure why i thought the water would evaporate out of them and they would shrink back down if i left them after using them, but... they do not shrink, fyi. I think these are great for shipping or in a situation where you're concerned about getting your ice pack back, (depending on current selling price). For example, if you have a kid that sometimes accidentally throws away their ice pack, then cutting off the appropriate number of rectangles from one of these might be a less expensive loss than a larger ice pack... but again, these aren't as durable. Also, if condensation from a traditional ice pack would degrade paper wrappers or whatever you're trying to keep cold, these would not have that problem. These are somewhat more moldable to different size/ shaped packages, so that's another advantage. If this is what kind of thing you're looking for, this is a very solid product and I'm happy with it.
