Temperature intentPlan around 0-4 C or the product label requirement, with pre-chilled meals loaded quickly into the shipper.
Chilled Ready Meals Cold Chain Packaging Solution
Chilled ready meals often combine trays, sealed films, sauce compartments, sleeves, labels, and sometimes mixed protein or vegetable components. The packout needs reliable 0-4 C control without flexing trays, creating wet sleeves, or pressing frozen gel packs against the film lid.
What the package needs to control
Coolant ruleUse conditioned gel packs or 0 C PCM around the tray stack, separated by a spacer so the top tray is not pressed by frozen packs.
Packaging focusTray support, sauce control, label dryness, and consistent stacking are as important as the temperature curve.
Choose the packout by route condition
| Route condition | Packaging setup | Preliminary coolant range | Placement and receiving check |
|---|---|---|---|
| Local delivery, 4-8 h | Insulated carton or small EPP box, snug tray insert, liner, side gel packs. | 0.4-0.9 kg gel packs or PCM for a 1-3 kg payload. | Keep trays flat; place coolant on sides instead of directly on film lids. |
| Same-day or overnight, 8-24 h | EPP or insulated carton, tray divider, leak liner, top and side coolant with spacer. | 0.9-2.0 kg gel packs or PCM for a 2-5 kg payload. | Check meal core temperature, sauce cup seal, sleeve dryness, and tray movement. |
| Warm route or possible delay, 24-36 h | Thicker insulation, balanced side/top coolant, stronger tray support, absorbent layer. | 2.0-3.4 kg gel packs or PCM for a 2-5 kg payload, route tested before launch. | If sleeves get wet, improve liner and spacing before simply adding more coolant. |
Use these ranges as a starting point for packaging review. Confirm the final coolant mass with the product label, pre-chill state, shipper size, route duration, ambient profile, and a temperature logger test.
How Tempk would build the shipment
Pre-chill the meals and shipper area
Load chilled meals quickly so the coolant is maintaining temperature, not trying to pull down a warm tray stack.
Support the tray stack
Use a snug inner carton, paperboard divider, or molded insert so trays do not flex or rub during courier handling.
Separate coolant from film lids
Gel packs should cool the payload cavity without pressing directly on the top tray or freezing sauce areas.
Inspect quality, not just temperature
At receiving, record temperature, tray cracks, sauce leakage, sleeve dryness, label condition, and remaining coolant.
Common failure points to prevent
For prepared foods, a cold arrival is only part of the decision. The shipment also needs to look clean, stay dry, protect texture, and pass the receiver’s quality check.
- Tray seal failure or cracked corners from pressure.
- Sauce migration after side handling or vibration.
- Wet sleeves and unreadable labels from condensation.
- Cold spots where frozen gel packs touch the top tray.
Validation curve and receiving evidence
Review the curve with the actual product, coolant mass, shipper size, lane duration, and season. Add arrival photos and receiving notes so the packout is judged by temperature and product condition together.
