What’s in a Gel Pack?

Gel packs are found everywhere, in homes, hospitals, schools, pharmacies and groceries. Their purposes can greatly vary, but most commonly, we know them for treating injuries and keeping our food cold. However, gel packs can be more practical than one can think of, for instance, in the cold chain industry, which is a crucial component in maintaining temperature range profiles.


Ice Packs and gel packs are used daily and at multiple times, some pharmacies and hospitals can use up to 10, 000 units daily, making gel packs a critical element in protecting temperature-sensitive products like vaccines and drugs. Typically, gel packs are made with temperature-sensitive ingredients which are sealed inside a protective malleable bag. If we’re talking about reusable ice packs, then these packs would contain water, propylene glycol, a thickening agent, silica gel and in some cases a non-toxic coloring agent. The water is usually used to help lower the freezing temperature, which can be advantageous or disadvantageous depending on the type usage.

Gel Packs are versatile and can be implemented in different cases. Whether it is for keeping fruits and vegetables, frozen food, vaccines, drugs, at a controlled temperature, utilizing gel packs and freezer packs are a universal and cost effective way to maintain consistent temperature for thermo-sensitive products. At the manufacturing point, storage facilities, and distribution centers, gel packs come in handy for maintaining the integrity of transported merchandise to the consumer.
