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, saison, taille de la commande, and carrier time.

Intention de températurePlan a cold non-freezing route, souvent autour 0-4 C or the supplier's specified range, with moisture and ventilation requirements matched to the shellfish program.
Contrôle de l'humiditéUse 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.
Contrôle de validationConfirmer la température du produit, état du colis, emplacement du liquide de refroidissement, 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, carrier lane, et assaisonner.

État de l'itinéraire Intention de température Tempk packaging setup Coolant planning range Emplacement du liquide de refroidissement
Local restaurant delivery, 8-18 h Cold and damp, pas gelé Insulated carton or EPP box, shellstock bag or tray, damp liner, fond absorbant. 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 h 0-4 C planning range unless supplier states otherwise Isolation plus forte, 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 h Validated non-freezing lane Isolation supérieure, 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, étiquetage, 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, pas seulement la température

Check shell closure, odeur, humidité, shell damage, tag condition, and any freezing signs.

Common losses this packout is meant to prevent

Use these receiving checks when adjusting coolant quantity, épaisseur d'isolation, 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.

Outils, composants, and related seafood routes

Use the product page for the packaging logic, then use the tools to size the first trial packout before a lane test.

First calculation

Run the coolant estimate

Utiliser le poids de la charge utile, taille de boîte, temps de parcours, and seasonal temperature before finalizing gel pack or PCM mass.

Coolant family

Choose coolant behavior

Compare frozen gel packs, packs de gel conditionnés, et 0 C PCM so the product is cooled without direct freeze injury.
