Run the coolant estimate
Gunakan berat muatan, ukuran kotak, waktu rute, and seasonal temperature before finalizing gel pack or PCM mass.
Near-ice seafood route
Tuna Steaks Cold Chain Packaging Solution
Tuna steaks are sensitive to warm dwell time, perubahan warna, perpindahan bau, 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.
Maksud suhuUse a near-ice chilled route, commonly planned around 0-2 C for quality, and follow the seafood safety plan for histamine-sensitive species.
Kontrol kelembabanUse liner and absorbent layers so leakage or condensation does not reach the outer carton.
Coolant ruleDo not rely on a light chilled meal-kit packout for tuna steaks. Tuna needs tighter dwell control, isolasi yang lebih kuat, and clearer receiving checks than many prepared foods.
Pemeriksaan validasiKonfirmasikan suhu produk, kondisi paket, posisi pendingin, and receiving quality together.
Choose the packout by route condition
The coolant amounts below are starting ranges for planning. Final packout should be validated with the exact payload, insulation size, jalur pembawa, dan musim.
| Kondisi rute | Maksud suhu | Tempk packaging setup | Coolant planning range | Posisi pendingin |
|---|---|---|---|---|
| Same-day premium delivery, 8-18 H | 0-2 C dingin | EPP shipper or insulated carton, sealed product bag, lapisan penyerap, penghalang bau. | 0.7-1.3 kg conditioned gel packs or 0 C PCM for 1-3 muatan kg. | 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 | Isolasi lebih tebal, tighter void fill, leak liner, temperature logger near product. | 1.4-2.4 kg gel packs or PCM for 1-3 muatan kg. | 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 muatan kg. | If validation cannot hold target, upgrade insulation or service level before adding uncontrolled coolant mass. |
For a tighter first estimate, gunakan Kalkulator Paket Es and then compare coolant families in the Pendingin & PCM Reference.
Packout sequence that protects product quality
Small layout changes can decide whether the receiver sees a clean chilled seafood parcel or a wet, pressured, partially frozen product.
1
Control dwell before packing
Keep tuna cold before handoff. A warm staging table can create more risk than the parcel transit itself.
2
Use low-pressure separation
Add a divider between coolant and product, then use void fill that prevents movement without crushing steak edges.
3
Place the logger in product air space
Do not tape the logger to the coolant. The receiver needs to see the environment the tuna experienced.
4
Inspect for quality loss
Check receiving temperature, surface color, bau, package leaks, vacuum seal condition, and evidence of coolant contact.
Common losses this packout is meant to prevent
Use these receiving checks when adjusting coolant quantity, ketebalan isolasi, or internal separation.
Quality and packaging risks
- Temperature abuse from long pickup dwell or a delayed final-mile stop.
- Color dulling or surface dehydration when liners and coolant position are poorly matched.
- Pressure marks from top-loaded frozen packs.
- Odor transfer into retail packaging or subscription boxes.

Use the product page for the packaging logic, then use the tools to size the first trial packout before a lane test.
Choose coolant behavior
Compare frozen gel packs, paket gel yang dikondisikan, Dan 0 C PCM so the product is cooled without direct freeze injury.
Periksa risiko jalur
Review lane time, penjemputan tinggal, penundaan mil terakhir, and receiver process before launch.
