Techni Ice HDR 4 Ply Reusable Ice & Heat Packs 6 Sheet Special

These Techni Ice Sheets are the best. The majority of the other brands out there have a cloth-like backing which tear easy and they have a tendency to leak. Techni Ice Sheets do not have the cloth backing and are much more durable and sturdy. Yes, they cost more but are definitely worth it. I always take a couple with me to put in my cooler bag when I go grocery shopping. These will easily stay frozen/cold for the entire day.

HOW TO GET THE MOST OUT OF THESE MAGICAL ICE THINGSI believe the reason why some people had issues with these is because they didn't read all the instructions and the tips provided by Techni Ice. Techni Ice should really provide more detailed instructions with the package. Below I will share the additional information from the Techni Ice website.TOP NOTES----------------------------------------------------------------------------------1. The most important thing to understand here is that the colder your freezer is, the better these things will perform. Techni Ice can be frozen as low as your freezer temperature can go (40c if you have a deep freezer).2. These things are NON-TOXIC! If it leaks a bit, don't worry about the gel. According to the Techni Ice website, you can put it on your tongue or skin and it will not harm you!3. Use 1 sheet per 7-8 liters of space. Ideally, everything you put in your cooler should be pre-chilled before hand. The colder everything is before you load your cooler, the better Techni Ice will perform.HOW TO USE----------------------------------------------------------------------------------1. Fill your sink or bath tub with the warmest water you can comfortably put your hands in for an extended period of time. Techni Ice hydrates faster in warm water.2. Scrunch up the Techni Ice sheet to get as much air out of the cells as possible. You should see bubbles coming out of them. There are tiny holes on both sides. Be sure to scrunch them up every which way paying particular attention to the cells in the middle of the sheet. Let the sheet absorb some water and then do the scrunching then again. It should be obvious when the cells are full.3. Sandwich the sheet between some towels and apply gentle pressure to get some of the water back out. Ideally, you don't want the cells 100% full because when the cells freeze the material inside will expand and may rupture the cells. If you have time, leave the sheets out in open air to dehydrate for 1-2 days. You want the outside of the sheets to be as dry as possible before loading them into the freezer.4. Freeze the sheets as cold as you can get them. The colder and longer you leave them in the freezer, the better they will perform. According to Techni Ice, it can take 2-3 days for the sheets to reach their coldest temperature.5. When using the sheets, you can fold them in half and place them in a gallon sized zip-lock bag to prevent any of the gel material from seeping onto other items in your cooler. The main thing you need to be concerned with is preventing the sheets from absorbing more liquid from your cooler. If you put regular ice in the cooler, make sure that it is also bagged.IMPORTANT NOTE: Cold sinks from top to bottom! When arranging the ice in your cooler, ideally, you should line the walls as high as you can get it. Also make sure that there is a blanket of ice on the very top.STORAGE: When not using your Techni Ice packs they can be stored in an open plastic bag in a cupboard or freezer. They are virtually maintenance free, but can be run under the water every so often to maintain or regain hydration. Remember to leave a thumb indentation in each cell for room to expand whilst freezing.FREQUENTLY ASKED QUESTIONS (from Techni Ice website)----------------------------------------------------------------------------------1) Why does Techni Ice last longer than regular Ice?Answer: YES, ice melts at 33 degrees and turns into water. Techni Ice keeps releasing cold air up to room temperature (most refrigerators are set at 45 to 47 degrees. As long as your food and or your drinks are still cool & dry you can eat or drink them). Techni Ice can be frozen as low as your freezer temperature can go (40c if you have a deep freezer).2) What is the difference between Techni Ice and Blue Ice?Answer:Techni Ice can be used for heat also, blue ice can't; Blue Ice is a liquid base while Techni Ice is a Polymer Crystal Base that will not stain or harm the environment or foods because it is similar to polymers that are used in baby diapers, and the Agricultural Industry uses them for holding water for plants.Techni Ice sheets are made up of 24 individual cells; if one of the cells breaks you only lose the one cell with Blue Ice, if you puncture it, you lose the whole product.Techni Ice creates a blanket of cool air while Blue Ice stays in one position in your cooler. Techni Ice is flexible and it can be wrapped around food or drink and thus produces a blanket of cool air, while blue ice stays in one location in your cooler. Since Techni Ice are individual cells when one cell goes from solid to gel it doesn't melt the other cells. But when Blue Ice goes from solid to liquid the whole package chain-reacts and defrosts.3) Why doesn't the water come out of the cells?Answer: The water enters the tiny holes per cell in Techni Ice and mixes with the crystals and becomes a polymer gel and thus the polymer gel has a bigger molecular make up and since the gel is bigger than the tiny cells, it won't come out4) Will Techni Ice contaminate my food? Is it toxic?Answer: No! It is a polymer crystal gel similar to what they use in baby diapers and is what the Agriculture Industry uses to hold water for vegetation. It is nature friendly and non-toxic. Place a dab on your tongue, rub it on your skin, it won't hurt you!5) Can you cut Techni Ice?Answer: Absolutely! Remember, it's flexible and adaptable. You can cut each sheet into 24 individual cells or any configuration that suites your needs. From a soda can to an aching neck, Techni-Ice fits! (Be sure to cut between the cells, not where the polymer gel is).6) How do you activate Techni Ice?Answer: You submerge It. in warm to hot water and scrunch it from side to side from top to bottom evenly. You do this for approximately 4 to 6 minutes or until hydrated (you should be able to put a thumbprint in each cell. The reason for the thumbprint is when you put anything into the freezer it expands 10%, so you must leave some room for expansion when frozen). If you over hydrate your Techni Ice, just lay it on a counter for 1 to 2 days or put it in the microwave a few times to dehydrate it.7) How many sheets do I need?Answer: You need one sheet per 8 Quarts of space in a cooler. An example is a 54-quart camping cooler needs 6 to 8 sheets to give the full cooling benefit of the Techni Ice. A day cooler needs 2 to 4 sheets, and a lunch box cooler needs only 1 to 2 sheets to keep your lunch cool all day.8) How long does Techni Ice last?Answer: It depends on how often you open and close your cooler, how many sheets you use, how cold you froze the Techni Ice (recommended time of freezing is 24 to 36 hours before using. The longer you freeze, the colder your freezer, the quality of your cooler, the longer it will last). A typical camping cooler with Techni Ice should give you 1 to 4 days approximately of lasting coolness, a day cooler will last a day, and a lunch box will last through a normal lunch period.9) How often can you freeze Techni Ice and how durable is it?Answer: Remember Techni-Ice is a replacement product Forget those messy water ice cubes that promptly melt and make a soggy mess in your cooler. You can freeze Techni Ice as often as you like. With proper use, you will have years of benefit from Techni Ice.10) Can I use Techni Ice with Ice?Answer: Yes, you could, but why bother? You must put either the Techni Ice or the ice in a waterproof bag so the water from the ice doesn't melt onto the Techni Ice. If it does melt onto the Techni Ice the Techni Ice will absorb the liquid and melt quicker (It will also make the Techni Ice too full and when it expands in the freezer it will probably burst or split because it is too full).11) How should I store the Techni Ice?Answer: The best place to store the Techni Ice is in the freezer. However, If you have a frost-free freezer, it will most likely dehydrate a little. If this happens all you have to do is re-hydrate the sheets in warm to hot water again for just a few moments or until a thumbprint can be put in each cell. You can also store it in an open plastic bag and lay it on a shelf. It too will dehydrate eventually. All you have to do is re-hydrate again for a few minutes or until you can put a thumbprint in each cell12) How do you heat Techni Ice?Answer: Place it in a microwave oven for, to begin with, one minute. If you need it hotter, just add time to your microwave oven until you reach the desired temperature. It is recommended that, if frozen, defrost the Techni Ice first.13) How should the Techni ice be placed in the cooler?Answer: You can either put some on the bottom first, then circle the edges of the cooler or layer it with food, then add a layer of Techni Ice, then food, then Techni Ice, etc.14) Why should I heat the Techni Ice?Answer: You can make a hot pack for your body or use it to keep food warm. Be careful not to overheat Techni Ice; just like the baby's bottle, touch it gently to your wrist and adjust the temperature as needed. Be sure to put a towel or clothe between the spot to be treated and the Techni-Ice. This way you will feel the benefit of warm heat without the discomfort of plastic on your skin.

I was given a couple of these ice sheets many years ago, and have been using them in my Golf Cooler Bag for years. They work great, bending to fit inside the smaller cooler, and around the bottles of "water" inside. They finally started to show signs of wear, and I was surprised to find them still on the market, and now in a new improved version. New version is nearly identical to the older ones, and work just as well.

Love the fact that they stay super cold. I use them for frozen foods. Only issue is that they can occasionally split, which leads to a film coming out of them which can be inconvenient. That happens after a while of use though, so the value is still good. Nothing lasts forever, so I do have to replace them from time to time.

I use these every day in my "personal refrigerator." Everyone talks about this weird slime and it's weird alright. I don't know why it has this. But the bottom line is that these WORK. If you get the full set DO NOT SOAK THEM ALL. Save a couple of sheets. My freezer is now full of these dang things and I only use four 6 x 6 sheets (cut them when they are dry and flat).I first soaked them in a CLEAN tub of cold water, "smooshing" them with my hands as directed to get the bubbles out, and then went and turned the freezer to the lowest setting. I let them soak for about 2 hours because I forgot about them.They worked great until the slime. I didn't want to eat my bananas or anything that touched it, and I had to Lysol the personal refrigerator every day. So I bought some Ziplock freezer bags to put them in and now - No slime AND they stay COLDER longer for whatever weird reason. When I get home after a 10 hour day, most of them are still frozen. Plus, now that they are in the freezer bags, I don't have to pull out and rearrange them back into the freezer. I just slide them in on top of one another. I also didn't keep the freezer at the lowest setting after that first freeze - just FYI.Some of the cubes on the sheets never inflated with the water so I just threw those out. You will have more than enough - trust me.I would totally buy this again.

The techni ice is great for using after oral surgery. it molds around my jaw and helps to keep the swelling down. Also great for throwing in a pack to transport frozen items on trips.

Absolutely brilliant for keeping things cold for a long period BUT trying to defrost them in order to store and reuse them is a nightmare and very messy. I've now given up and thrown them away. So a good but very expensive one-off solution in the end.

Perfect for my needs

Leak their horrible slimy contents. Have reverted to a nice big bag of ice…
