RAINBOW Dry Ice Packs for Shipping Long Lasting, Reusable Cold Ice Pack Sheets for Lunch Box, Flexible Dry Ice Packs for Coolers, Dry Ice for Shipping Frozen Food, 24 Ice Cells Each Sheet, 4 Sheets

Ice packs worked perfectly for shipping almost 160oz of frozen breastmilk to a friend. They were easy to “start” & get frozen. Loved that they were lightweight & didn’t take up much room. No leaks. Best part: they kept the milk perfectly frozen on the overnight trip multiple states away!!

Keeps my food cold for at least 6 to 8 hours. Great product.

Works just as advertised.

I think these are pretty awesome. They swell up fairly good sized creating a nice amount of cold mass. I use two sheets in my lunch box. Each sheet is perfectly sized to lay flat in the box. I lay one sheet on the bottom, put my container of leftovers, usually a string cheese or single server pack of cottage cheese then place another sheet on top. This keeps my lunch cold for the next 6+ hrs. Often the cottage cheese is very firm when I go to eat it. More so than if I ate it out of the fridge.The only thing I don't care so much about is, the absorbent bubbles do over time lose mass. You can resoak them but they don't seem to restore to the same size as a new sheet does. Eventually after probably four or more months of daily (M-F) use, they're be down to maybe half their initial swelled size. They still keep my lunch cold but not as cold. so I'll just toss 'em and soak two new sheets. Also occasionally a bubble will break open at a seem and ooze the absorbent gel. When this happens I just cut out that bubble. When it gets down to three or four cut out from a sheet, I'll just toss it and soak a new one.Overall I think it keeps my lunch colder because the mass is spread out across my whole lunch box, not just one or two concentrated blue ice packs. Their flexibility allows them to mold around a bit and sit closer to the food.

I use these dry ice sheets for shipping chocolate products for my small business during the hot summer months. They are very convenient to use. I cut them into smaller sizes, soak them in water for about 10 minutes and then freeze them for about 24 hours and they are ready to use. I use mylar blankets to wrap my product in with the ice packs and they last for a long time keeping everything cool.These dry ice sheets will do a good job of keeping food and beverages cold for an extended period. They stay frozen for a long time.One of the best features of these dry ice sheets is their ease of use. They come in a flexible sheet form, which can be cut to size or shaped to fit around various items. This adaptability is fantastic for packing coolers efficiently. They are also lightweight, which is a significant advantage for camping and traveling.The reusability factor is a major plus. Unlike traditional ice that melts and needs replacing, these dry ice sheets can be refrozen and reused multiple times. This not only saves money in the long run but also reduces waste, making them an environmentally friendly option.The only downside I encountered was the initial cost. Dry ice sheets are more expensive upfront compared to regular ice packs. However, given their effectiveness and reusability, I believe the investment is worthwhile. Additionally, they can be harder to find in local stores, so purchasing online may be necessary.Overall, I highly recommend dry ice sheets for anyone needing reliable cooling solutions, whether for camping, picnics, or transporting perishable items. They offer superior cooling performance, are easy to handle, and provide excellent value over time. Despite the higher initial cost, their effectiveness and reusability make them a great addition to any cooler setup.

When reviewing this product, it clearly states 12 cells per sheet and “eight sheets.”Yes, it has 12 cells per sheet, but I have ordered this twice now and both times when it is arrived it only comes with ONE single sheet.

Ice packs worked to transport frozen beef for a 900 mile trip. Only used half the quantity.

The non-plastic side is pretty fragile - didn't take long to rip, especially since the sheet sticks to itself so easily.I use these ice sheets at our business to keep the product cool, but they don't do a great job because they lose volume pretty quickly.Won't purchase again.
