A Sustainable Alternative to Freezer Bricks

Freezer bricks are a single-use refrigerant product that is widely used in the cold chain. They solve the shape-shifting problem that gel packs have. Freezer bricks contain a foam brick that holds its shape through freeze/thaw cycles, which can be helpful for dimensional consistency in packing out a cold parcel for example.

Phenolic compounds have been listed by the United States Environmental Protection Agency (EPA) and the European Union (EU) as pollutants of priority concern. This enlistment is due to the fact that these chemicals are noted to be toxic and have severe short‐ and long‐term effects on humans and animals.

Our new Structured Gel is a plant-based, biodegradable, non-toxic Cold Pack that can put the Freezer Brick on ice for good. Shape-constant material that will freeze and thaw in its original form, our Structured Gel has more in common with a solid than a liquid. One of the additional benefits to our Structured Gel is that we are able to produce a fully LEAK-PROOF gel pack.
