FAQ

This will depend on the insulation used in your shipping box and your packaging method. Generally speaking, the ice packs will stay frozen from 24-36 hours in an insulated container. At room temperature, figure on about 3-4 hours. Most importantly, they will maintain stay frozen longer than ice!

These ice packs cost about half as much (or less) as gel packs on a per pound basis (hydrated).

Cut them to your preferred size, then hydrate for up to 1 minute. Wipe ice packs down after hydrating and freeze for 24 hours. Place the ice packs in your insulated box or cooler as needed.

Protecting almost anything that needs to be kept frozen or refrigerated. The ability of these flexible ice packs to drape and/or wrap around large or unusually shaped items makes it incredibly versatile. These ice packs should not be used alone for products requiring temperature maintenance below 32 degree Farenheit, but they can be used to extend the performance of dry ice when used together. They also make a great first aid item for bumps and bruises, headaches, etc.

Indefinite if stored in a plastic bag to prevent it from absorbing moisture from the air. Like salt and sugar the powder needs to be kept dry. A plastic bag works well.

No. Simply email us your request.

Yes, they can be re-hydrated and re-frozen times over and over.

The ice packs measure 3.3" x 3.7" and absorb 2.3 oz. of water when hydrated.

Because these ice packs can be placed so much more efficiently around your items, you will need fewer ice packs than gel-packs by weight in most applications. Exactly how much less will vary with different packaging methods and the products being shipped.

If a cell gets punctured and some gel leaks out, don't worry. The gel is non-toxic and will do no harm, simply rinse it off with water.

The ice packs are environmental friendly and may be incinerated or sent to a landfill.

Absolutely! When the water is absorbed it bonds with the super absorbent powder and forms molecules of gel. The gel molecules are cross-linked with each other and they are much too large to fit through the small openings in the fabric that allowed the water to get into the cell. Therefore, the only way to get the water out of the cell once it has been absorbed is to apply so much pressure to the cell that it ruptures the plastic.

Absolutely. they are excellent at absorbing many liquids.

Not at normal freezer temperatures. If the ice packs have been in contact with extreme cold (e.g. dry ice) it will maintain that extreme temperature for a time and should be handled with the same care as any similarly cold item (insulated gloves are usually adequate).

Yes, used along with dry ice you can cut the volume of dry ice needed by up to 50%.

It does not matter because all products shipped in direct contact with any refrigerant product should be wrapped in plastic or placed inside a cheap plastic bag. This prevents possible water damage from condensation that results from any type of frozen refrigerant in contact with your product's packaging.

Any refrigerant will last longer if more is used. It is like a trip to the beach - the more ice you put in the ice chest to keep your drinks cold, the longer the drinks will stay cold.

Nothing, but they are designed to absorb fast so you can freeze them in minutes after you put them into the water. If you leave them in the water too long they will be as tight as a drum and they may be more susceptible to puncture.
