Can Ice Gel Packs Stay Cold 48 Hrs Like Dry Ice?
Can ice gel packs stay cold 48 hrs like dry ice? Yes—ice gel packs stay cold 48 hrs like dry ice when you match PCM setpoint, insulation, and packout to your lane and validate with an ISTA‑style 48‑hour thermal test. Design frozen routes to ≤0 °F (−18 °C), choose −20/−23 °C PCM for “frozen‑class,” and use thicker EPS/PUR or VIP to stretch hold time. Then prove it with a data logger before scaling.
