Run the coolant estimate
Usar peso da carga útil, Tamanho da caixa, tempo de rota, and seasonal temperature before finalizing gel pack or PCM mass.
Tuna steaks are sensitive to warm dwell time, mudança de cor, transferência de odor, and pressure marks. A useful packout keeps the product close to ice temperature, shortens uncontrolled pickup or receiving time, and keeps coolant from touching the steak surface or vacuum pack directly.
The coolant amounts below are starting ranges for planning. Final packout should be validated with the exact payload, insulation size, carrier lane, e estação.
| Condição da rota | Intenção de temperatura | Tempk packaging setup | Coolant planning range | Posição do refrigerante |
|---|---|---|---|---|
| Same-day premium delivery, 8-18 h | 0-2 C chilled | EPP shipper or insulated carton, sealed product bag, camada absorvente, barreira contra odores. | 0.7-1.3 kg conditioned gel packs or 0 C PCM for 1-3 kg de carga útil. | Perimeter coolant. Keep frozen packs away from the steak face and vacuum seal edges. |
| Overnight route, 18-36 h | Near-ice route with short dwell | Isolamento mais espesso, tighter void fill, leak liner, temperature logger near product. | 1.4-2.4 kg gel packs or PCM for 1-3 kg de carga útil. | Use side plus top coolant separated by board or pouch; prevent pressure dents. |
| Hot lane or remote delivery, 36-48 h | Validated chilled lane only | Pre-qualified shipper size, reduced headspace, route risk check before launch. | 2.5-4.0 kg gel packs or PCM for 1-3 kg de carga útil. | If validation cannot hold target, upgrade insulation or service level before adding uncontrolled coolant mass. |
For a tighter first estimate, use o Calculadora de bolsa de gelo and then compare coolant families in the Refrigerante & PCM Reference.
Small layout changes can decide whether the receiver sees a clean chilled seafood parcel or a wet, pressured, partially frozen product.
Keep tuna cold before handoff. A warm staging table can create more risk than the parcel transit itself.
Add a divider between coolant and product, then use void fill that prevents movement without crushing steak edges.
Do not tape the logger to the coolant. The receiver needs to see the environment the tuna experienced.
Check receiving temperature, surface color, odor, package leaks, vacuum seal condition, and evidence of coolant contact.
Use these receiving checks when adjusting coolant quantity, espessura de isolamento, or internal separation.

Use the product page for the packaging logic, then use the tools to size the first trial packout before a lane test.
Usar peso da carga útil, Tamanho da caixa, tempo de rota, and seasonal temperature before finalizing gel pack or PCM mass.
Compare frozen gel packs, pacotes de gel condicionado, e 0 C PCM so the product is cooled without direct freeze injury.
Review lane time, tempo de coleta, atraso na última milha, and receiver process before launch.
Share the seafood form, peso da carga útil, Tamanho da caixa, nível de serviço, origin temperature, temporada de pista, and receiving window. Tempk can help compare insulation, massa de refrigerante, colocação, e etapas de validação.
