Cryopak’s IcePak Bricks phase at 0° C and offer thermal performance of gel packs, yet maintain their shape even after they’re frozen.
The packs employ 4-mil polyethylene film; each brick is vacuum-sealed
to insure consistent dimentional tolerance. Available in custom sizes;
used with Tempak™ EPS and PU-insulated shipping containers, or in
conjunction with Cryo-Gel™ gel packs.
