Chilled Mixed Grocery Pallets
Control 2-8 C chilled routes while protecting airflow, mixed SKU compatibility, condensation, carton strength, and dock exposure.
Cold Storage & Pallet Logistics Cold Chain Solutions
Pallet cold chain planning is not parcel packaging scaled up. The route must account for pallet mass, warehouse airflow, dock exposure, stretch-wrap tension, edge warming, carton compression, and logger positions across the top, exposed edge, core, and lower layers.
Choose the pallet plan by load type
A chilled mixed grocery pallet, frozen meat pallet, and frozen seafood pallet may all pass through the same warehouse, but the failure points are different. Tempk plans the cover, liner, airflow, dry ice option, and logger map around the actual load.
Frozen Meat Pallets
Protect -18 C frozen lanes from edge thaw, carton compression, frost melt, and open-door transfer risk.
Frozen Seafood Pallets
Maintain frozen control while managing glaze condition, leakage, seafood odor separation, and exposed edge cartons.
Typical pallet route choices
| Pallet route | Temperature intent | Load protection setup | Coolant or cover planning | Check at receiving |
|---|---|---|---|---|
| Chilled mixed grocery pallet, cold room to reefer, 2-12 h | Use the strictest product requirement on the pallet; many mixed grocery lanes are planned around 2-8 C. | Pre-cooled pallet, airflow-aware wrap, carton-strength stacking, thermal cover or liner for dock exposure. | Primary control should be the refrigerated lane. Add gel packs or PCM only in a validated insulated pallet plan, often 8-25 kg for exposed handoff or passive buffer lanes. | Top/edge/core temperature, wet cartons, crushed soft cartons, odor transfer, wrap movement, and receiving delay. |
| Frozen meat pallet, frozen warehouse to reefer, 4-24 h | Common frozen planning target is around -18 C; protect exposed edges and avoid partial thaw during transfer. | Frozen pallet cover or liner, corner boards, heavy-carton pattern, protected exposed edge, dry dock transfer limit. | Use active frozen transport as the main control. Dry ice may be planned for validated backup or passive segments, commonly 10-50 kg per pallet depending on lane, pallet size, and allowed handling rules. | Edge and core temperature, carton strength, frost melt, drip signs, wrap stability, and remaining dry ice if used. |
| Frozen seafood pallet, frozen warehouse to reefer or cross-dock, 4-24 h | Plan around frozen control, often near -18 C, with attention to surface glaze, leakage, and odor separation. | Frozen cover or liner, leak/odor separation, stable carton pattern, exposed edge protection, top-edge-core logger map. | Use reefer control first. Dry ice or frozen pallet shroud can be considered for validated exposed lanes, commonly 10-55 kg per pallet depending on duration and pallet mass. | Glaze condition, leakage, odor transfer, edge thaw, carton wetting, logger map, and remaining dry ice if used. |
These ranges are starting points for sampling and route discussion. Final coolant or dry ice mass must be confirmed by pallet size, product mass, regulatory and carrier rules, route duration, ventilation, ambient exposure, and receiving procedure.
How Tempk builds a pallet route plan
Pre-condition the pallet before wrapping
Load from stable cold storage. A cover, liner, or coolant plan should hold the route, not remove heat from a warm pallet.
Protect airflow and pallet stability
Stretch wrap, carton pattern, air gaps, and cover fit should work together. Over-wrapping can trap warm zones; weak stacking can crush lower cartons.
Use coolant only where it belongs
Gel packs, PCM, or dry ice can support some pallet routes, but they should not replace a required refrigerated or frozen lane unless the passive pallet setup has been validated.
Map the real temperature positions
Use loggers at the top, exposed edge, core, and lower pallet positions. One center logger can miss edge warming or top-layer exposure.
Route validation image
The pallet curve helps compare dock exposure, pallet cover performance, and logger locations. Read it together with receiving checks for carton condition, leakage, frost, odor, wrap shift, and exposed-edge quality.
