Estimate coolant mass
Usar peso da carga útil, Tamanho da caixa, duração da rota, and ambient season before the first lane test.
Seafood subscription boxes need chilled temperature control, contenção de gotejamento, odor protection, and a clean unboxing experience. Peixe fresco, marisco, and mixed seafood packs should stay cold without direct coolant pressure, standing meltwater, or carton wet-out.
The coolant amounts below are starting ranges for planning. Final packout should be validated with the exact order mix, tamanho do remetente, carrier lane, e estação.
| Condição da rota | Intenção de temperatura | Tempk packaging setup | Coolant planning range | Posição do refrigerante |
|---|---|---|---|---|
| Fresh seafood box, 8-18 h | 0-2 C or 0-4 C chilled route | Insulated carton or EPP box, leak liner, almofada absorvente, barreira contra odores, separated gel packs or 0 C PCM. | 0.8-1.6 kg gel packs or PCM for 1-4 kg de carga útil. | Top/side coolant with divider; avoid direct pressure on fish packs. |
| Overnight seafood subscription, 18-36 h | Near-ice chilled route | Isolamento mais espesso, sealed liner, base absorvente, logger in product air space. | 1.6-3.0 kg gel packs or PCM for 1-4 kg de carga útil. | Perimeter coolant plus separated top layer; keep seafood out of standing liquid. |
| Hot lane or delay risk, 36-48 h | Validated chilled lane | Maior isolamento, double leak containment, reduced headspace, route risk check. | 3.0-4.8 kg gel packs or PCM for 1-4 kg de carga útil. | If drip or odor escapes, improve liner and absorbent design before adding coolant. |
Use o Calculadora de bolsa de gelo for chilled routes. For frozen boxes, compare with the Calculadora de gelo seco before testing.
A good subscription box should hold temperature and still arrive clean, legível, separado, and easy for the customer to unpack.
Fish fillets, marisco, and mixed seafood boxes have different pressure, umidade, and odor risks.
Use um forro, almofada absorvente, and sealed inner layer so drip does not reach the outer carton.
Place gel packs or PCM above and around the seafood chamber with a divider to prevent freeze marks or pressure damage.
Check temperature, pingar, odor, condição do rótulo, carton wet-out, and whether coolant shifted during parcel handling.
Use these checks when adjusting coolant quantity, estrutura do forro, espessura de isolamento, or fulfillment timing.

Use the product page for handling logic, then size the first trial with tools and validate the real parcel route.
Usar peso da carga útil, Tamanho da caixa, duração da rota, and ambient season before the first lane test.
Compare conditioned gel packs, 0 C PCM, and dry ice where frozen delivery is required.
Review fulfillment dwell, atraso de retirada, exposição de última milha, and receiving window before launch.
Share the product mix, peso da carga útil, Tamanho da caixa, fulfillment dwell time, duração da rota, temporada, e recebendo padrão. Tempk can help choose insulation, massa de refrigerante, estrutura do forro, and validation checks.
