Shrimp and Prawns Cold Chain Packaging Guide for Seafood Delivery
Cold chain packaging guide for shrimp and prawns, covering chilled holding, drip control, pre-cooling, pressure protection, coolant placement, route duration, common losses, and Tempk seafood packout selection.
Why shrimp and prawns need a specific seafood packout
Shrimp and prawns have high surface area and release drip quickly. A packout that works for a thick fish fillet can still fail if small packs warm during sorting or leak into the outer box. Seafood packaging has to protect temperature and visible receiving quality together. A parcel can arrive cold but still fail if it leaks, smells warm, crushes delicate product, or wets the outer carton.
The packout should start from a cold product, use a seafood-safe inner liner, keep coolant separated from the seafood pack, and include receiving checks for temperature, odor, drip, texture, and carton condition.
Packout requirement table
| Cold chain factor | Shrimp and Prawns requirement |
|---|---|
| Target temperature | 0-2 C chilled, or -18 C or below when shipped frozen |
| Humidity and condensation | High drip and odor risk; keep seafood packs sealed and outer cartons dry |
| Pre-cooling | Load from cold storage and avoid warm bench time before the insulated shipper is closed |
| Packaging pressure | Medium. Small pieces compress easily and can leak through weak retail packs |
| Coolant position | Gel packs or seafood ice packs above and around the seafood zone with a leak barrier |
| Transit duration | Same-day to 48 h chilled parcel lanes after product-level route testing |
| Common losses | Warm odor, drip leakage, crushed packs, label wet-out, texture softening, and customer rejection |
| Tempk packaging response | Tempk insulated seafood shipper with sealed inner liner, conditioned gel packs, absorbent pad, product divider, and temperature logger |
Route design notes
Map each warm point in the route: packing bench time, carrier handoff, sort-center dwell, delivery vehicle dwell, and receiver delay. Seafood with high moisture or small pack size can warm and leak faster than dense fillets, so the inner layout should be approved with the real retail pack.
Use sealed liners, absorbent layers, tray support, and separated gel packs where needed. For live seafood, avoid freezing contact and standing water. For chilled processed seafood, focus on product temperature, drip control, odor control, and package dryness.
Tempk recommendation
A typical Tempk seafood packout uses an insulated shipper, conditioned gel packs or seafood ice packs, leak-proof liner, absorbent pad, product divider, coolant separator, and a product-level logger. Approve the packout after checking temperature, odor, drip, texture, shell or tray damage, and carton dryness after the actual route.
