Convenience of Ice Packs
Gone are the days when our only option for cooling was ice.
The development of ice packs many years ago have made cooling with ice
more convenient, and more innovations in the field has continued in the
recent years. Today, we can now enjoy the utmost convenience of
instant ice packs, also commonly called cold packs. These instant ice
packs typically look like a plastic bag that is filled with a gel-like
liquid. The cold pack is termed "instant" because once the sheet is
hit, shaken or disturbed, it immediately get extremely cold and the low
temperature gets retained for an extended time period.
The concept behind instant cold packs is scientific in nature. The
liquid inside is typically water, and somewhere inside the bag is a tube
or container that holds an ammonium nitrate or similar fertilizer.
Disturbing the cold pack initiates the mixing of the liquid and the
fertilizer, which is an endothermic reaction where heat is absorbed at a
rapid pace. As a result of the reaction, temperature then falls
rapidly and the ice pack stays cold for 10 to up to 20 minutes,
depending on the ice pack's cooling power.
ThermaFreeze, a leading brand in ice packs.
What makes them superior to other ice pack brands is that ThermaFreeze
ice packs do not involve the use of ammonium nitrate for the
endothermic reaction to ensure. Instead, they have developed a product
that is based on environmentally-friendly, natural, non-toxic and
biodegradable materials. ThermaFreeze ice packs are not only safer,
but easier to use and dispose of without harming the environment. They
are safe to use with food (FDA Approved) and with different parts of
the body, even during situations where the ice pack accidentally gets
