Run the coolant estimate
Use payload weight, حجم المربع, وقت الطريق, and seasonal temperature before finalizing gel pack or PCM mass.
Live chilled shellfish
Oysters Cold Chain Packaging Solution
Oysters are not handled like fish fillets. The packout must keep live shellfish cold and damp, protect shells and tags, avoid freezing injury, and prevent oysters from sitting in meltwater. The best design depends on shellfish rules, موسم, حجم الطلب, and carrier time.
نية درجة الحرارةPlan a cold non-freezing route, في كثير من الأحيان حولها 0-4 C or the supplier's specified range, with moisture and ventilation requirements matched to the shellfish program.
مراقبة الرطوبةUse liner and absorbent layers so leakage or condensation does not reach the outer carton.
Coolant ruleDo not seal live oysters in an airtight wet box or place frozen gel packs directly against shellstock. Cold injury and standing water can be as damaging as a warm route.
فحص التحقق من الصحةتأكيد درجة حرارة المنتج, حالة الحزمة, موقف المبرد, 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, ممر الناقل, والموسم.
| حالة الطريق | نية درجة الحرارة | Tempk packaging setup | Coolant planning range | موقف المبرد |
|---|---|---|---|---|
| Local restaurant delivery, 8-18 ح | Cold and damp, لا تجمد | Insulated carton or EPP box, shellstock bag or tray, damp liner, قاعدة ماصة. | 0.5-1.0 kg conditioned gel packs for small parcels, adjusted by order size. | Coolant above or beside shellstock with a divider; avoid direct shell contact. |
| Overnight live shellfish, 18-30 ح | 0-4 C planning range unless supplier states otherwise | عزل أقوى, non-airtight design where required, tag-protective inner layout. | 1.0-1.8 kg conditioned gel packs for small to mid-size parcels. | Keep shellfish out of standing meltwater and protect the harvest tag from moisture damage. |
| Hot season or longer lane, 30-48 ح | Validated non-freezing lane | عزل أعلى, route risk check, reduced headspace, earlier carrier pickup. | 1.8-3.0 kg conditioned gel packs, confirmed by seasonal test. | If shells show freezing, reduce contact risk before increasing coolant mass. |

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
Confirm shellfish handling requirements
Use the supplier's range, وضع العلامات, tag, and ventilation rules before choosing a closed shipper design.
2
Keep dampness separate from leakage
Use damp food-safe material for humidity and a separate absorbent base for meltwater or condensation.
3
Protect shells and tags
Pack oysters so they cannot crush labels or each other during parcel handling. Keep the shellfish tag readable at receiving.
4
Receive by condition, ليست درجة الحرارة وحدها
Check shell closure, رائحة, رُطُوبَة, shell damage, tag condition, and any freezing signs.
Common losses this packout is meant to prevent
Use these receiving checks when adjusting coolant quantity, سمك العزل, or internal separation.
Quality and packaging risks
- Freezing injury from gel packs touching shellstock directly.
- Mortality or quality loss from standing meltwater or airtight packing when ventilation is required.
- Broken shells and wet tags caused by poor internal bracing.
- Warm top layer when coolant is under the product instead of above or beside it.
