What temperatures are standard water-based cold packs best suited for?

Standard water-based cold packs are best suited for maintaining temperatures around 0°C (32°F), which aligns with typical refrigerated conditions. As the water-based gel melts at this temperature, it absorbs heat and helps keep the surrounding products within a narrow, controlled range.

For applications that require other temperature ranges (such as deep freezing or higher controlled temperatures), specialized PCMs formulated for those specific phase change points may be more appropriate.
