PCM bricks hold a fixed plateau temperature (على سبيل المثال, 5 °F or 28 °F), which stabilizes the box as heat enters. Gel packs span a wider band but excel for fridge‑range holds with no paperwork. Many shippers combine PCM + هلام to buffer hot lanes at lower weight and cost.

|---|---|---|---|
| 5 °F PCM brick | “Freezer‑like” assist | Frozen pastries/ice‑cream | قابلة لإعادة الاستخدام, simpler than dry ice |
| 28 °F PCM | Near‑freezing drinks | المشروبات & ينتج | Very cold, less freeze risk |
| حزمة هلام | 2–8 °C holds | Meal kits/dairy | لا خطر, easy scaling |
