Ice Cold Seafood Box — Built for 0–4°C Iced Fresh Transport
An ice cold seafood box is a waterproof, reusable shipping container engineered specifically for iced-fresh seafood — products stored at 0–4 درجات مئوية using crushed ice or gel packs rather than mechanical refrigeration or blast freezing. Unlike frozen-seafood packaging (designed for −20°C static storage) or general fresh-seafood boxes (designed for ambient or lightly chilled conditions), an ice cold box must solve one challenge that no other packaging faces: continuous ice-melt water management over 24–72 hours of transit.
Every kilogram of ice packed with seafood becomes roughly one liter of meltwater within hours. That water must drain away from the product — without leaking onto pallets below — while the remaining ice continues to keep the catch at food-safe temperature. PPBOXY’s Ice Cold Seafood Box is purpose-built for this exact cycle: load with ice → seal → stack → drain meltwater → replenish ice → repeat.

❌ No drain ports; water pools |
❌ No drainage; soggy bottom |
✅ Integrated drain ports; self-draining |
| Re-icing in transit |
❌ Must open box → break cold chain |
❌ Box too wet to reseal |

❌ Cracks under load when wet |
❌ Compresses when saturated |
✅ No deformation wet or dry |
| After 24h in meltwater |
❌ Seams split; beads detach |
❌ Disintegrates |
✅ Identical to dry condition |
How PPBOXY’s Ice Cold Seafood Box Manages the Melt Cycle
The ice-melt cycle in a PPBOXY Ice Cold Seafood Box works in four continuous stages:
- Pack — Layer product with crushed ice or gel packs inside the waterproof box. The twin-wall PP construction provides passive insulation, slowing ice melt by up to 30% compared to open-top EPS containers.
- Seal & Ship — Close the lid. Meltwater flows downward through the product bed — washing and chilling simultaneously — and exits through فتحات تصريف مدمجة at the base or sides. No need to open the box during transit.
- Drain & Monitor — Meltwater exits through drain ports without opening the box, so cold air stays trapped and internal temperature remains in the 0–4°C safe zone. External temperature indicators or RFID loggers can be mounted on the lid for compliance documentation.
- Replenish & Repeat — At distribution hubs, add fresh ice through the top opening. The box is already empty of standing water (drained), so new ice directly contacts the product. No drying step needed — unlike cardboard that must be replaced after a single wet cycle.

Key Features of the Ice Cold Seafood Box
Integrated Drain Ports for Ice-Melt Management
Every PPBOXY Ice Cold Seafood Box includes factory-cut drain ports positioned at the base or lower sidewalls — exactly where meltwater collects. Unlike aftermarket drilling (which creates sharp edges and weakens the structure), our integrated ports are clean-sealed during die-cutting for smooth edges and zero structural compromise. Available configurations:
| Drain Port Style |

Flow Rate |
| Bottom center (single) |

~2 L/min |
| Dual side ports (left + right) |
Large boxes, mixed loads |

~6 L/min |
All drain ports can be plugged with press-fit caps for dry transport or retail display — one box, two modes.
Twin-Wall & Honeycomb Insulation Options
PPBOXY offers two sheet constructions for ice cold boxes, each optimized for different transit durations:

الـ PP honeycomb construction is exclusive to this product line — no other PPBOXY seafood box offers it. The hexagonal cell structure traps a layer of still air between the inner and outer walls, providing superior thermal resistance without adding solid material weight. This makes it ideal for export shipments where ice must last 48+ hours without replenishment.
Food-Contact Safe (FDA / EFSA / EU 10/2011)
All PPBOXY ice cold seafood boxes are manufactured from البولي بروبيلين المخصص للاستخدام الغذائي متوافق مع:
- لائحة إدارة الغذاء والدواء الأمريكية (FDA) 21 CFR 177.1520 — بوليمرات الأوليفين المخصصة للتلامس مع الأغذية (الولايات المتحدة الأمريكية)
- لائحة الاتحاد الأوروبي رقم 10/2011 — المواد البلاستيكية التي تتلامس مع الأغذية (أوروبا)
- حدود الانتقال التي حددتها هيئة السلامة الغذائية الأوروبية (EFSA) — الهجرة المحددة والإجمالية ضمن الحدود الآمنة
- GB 4806.7 — المواد البلاستيكية الملامسة للأغذية (المعيار المحلي الصيني)
Critical for ice cold applications: meltwater is in continuous contact with both the product and the box interior for the entire transit duration. Unlike dry-storage packaging, an ice cold box must maintain zero chemical migration under prolonged wet contact — all PPBOXY boxes pass immersion migration testing at 40°C for 10 days (far exceeding the 0–4°C real-world condition).

Seafood Species Best Served on Ice
Not all seafood belongs in a freezer — and not all “fresh” seafood stays fresh without ice. Here are the species categories where iced transport at 0–4°C is the gold standard:
Whole Fish & Fillets (Ice-Packed)
Fresh whole fish — from Atlantic cod to Mediterranean sea bass — is traditionally buried in crushed ice from dock to market. The ice keeps the flesh at 0–2°C, slows bacterial growth by 10x compared to 8°C storage, and maintains the glossy eye and bright gill color that buyers at auction houses and wet markets use as freshness indicators. PPBOXY’s ice cold boxes are designed with elongated dimensions (up to 1200 mm) to accommodate whole round fish without tail-overhang, and drain ports positioned to keep the fish elevated above meltwater.
Shellfish — Oysters, Clams & Mussels
Live bivalve shellfish must remain moist but not submerged during transport. PPBOXY ice cold boxes for shellfish feature a perforated elevated base that allows meltwater to drain below while keeping oysters and clams in a humid — not flooded — environment. The twin-wall insulation slows ice melt, reducing the frequency of re-icing on routes longer than 12 hours.
Crustaceans — Lobster, Crab & Shrimp (Live or Chilled)
Live lobsters and crabs require cool (2–8°C), humid, oxygenated conditions — not freezing. PPBOXY’s ice cold boxes for crustaceans include فتحات تهوية دقيقة that maintain airflow while ice packs regulate temperature. For chilled (not live) shrimp and prawns, see our dedicated صندوق بلاستيكي مموج للروبيان with solid-wall insulation for cold-chain warehouse storage. For crab-specific handling, see our صندوق تعبئة سرطان البحر with reinforced drop-tested construction.
Squid, Octopus & Cephalopods
Cephalopods are among the most delicate seafood — their skin tears and discolors easily under rough handling. Iced transport at 0–4°C in smooth-walled PP corrugated boxes prevents skin damage while maintaining the translucent appearance that signals freshness in Asian and Mediterranean markets. The waterproof interior can be تم رشها بالماء بين قطع الأراضي without drying — a critical advantage over cardboard in high-volume squid processing.
Sashimi-Grade Seafood for Retail & Horeca
Sashimi and sushi-grade tuna, salmon, and yellowtail demand unbroken 0–4°C cold chain from processing to display — even a 30-minute excursion above 4°C can disqualify a batch. PPBOXY ice cold boxes with honeycomb insulation maintain sub-4°C for 24+ hours with standard ice loading, making them suitable for the final-mile delivery of sashimi-grade product to restaurants and retail counters. Custom-printed boxes reinforce brand identity for premium HORECA suppliers.
الأسئلة الشائعة
What is an ice cold seafood box?
ج: An ice cold seafood box is a waterproof, reusable PP corrugated container designed for iced-fresh seafood transport at 0–4°C. Unlike frozen-seafood boxes (−20°C) or general fresh boxes, it is engineered specifically for ice-melt management — with integrated drain ports that let meltwater exit without opening the box, maintaining the cold chain while keeping product elevated above standing water.
How does an ice cold seafood box differ from a frozen seafood box?
ج: Temperature and preservation method. An ice cold box maintains 0–4°C using crushed ice or gel packs — ideal for fresh whole fish, live shellfish, and sashimi-grade product. A frozen seafood box maintains −20°C for blast-frozen fillets and IQF product — see our صندوق شحن الأسماك المجمدة. Ice cold boxes need drain ports; frozen boxes need insulation. They serve different products and supply chains.
Which seafood species need iced (not frozen) transport?
ج: Most fresh-market seafood is best transported on ice, not frozen:
- Whole round fish (cod, sea bass, snapper) → Ice-packed in this box
- Live shellfish (oysters, clams, mussels) → Moist-iced in this box (perforated base)
- Live crustaceans (lobster, crab) → Cool-iced in this box (ventilated) or our صندوق تعبئة سرطان البحر
- Chilled shrimp/prawns → صندوق بلاستيكي مموج للروبيان (cold-chain warehouse)
- Frozen blocks/IQF → صندوق شحن الأسماك المجمدة (−20°C)
How do the drain ports work? Can they be sealed for dry transport?
ج: Integrated drain ports are factory-cut during die-cutting for smooth, sealed edges. Meltwater flows through the ports by gravity — no pumping or tilting required. For dry transport or retail display, each port includes a press-fit cap that seals the opening watertight. One box, two modes: drain-open for iced transit, sealed for dry storage or display.
What is the PP honeycomb sheet option, and when do I need it?
ج: PP honeycomb sheet is a hexagonal-cell structure that traps a layer of still air between inner and outer walls, providing 25–30% better insulation than standard twin-wall fluted sheet. It is recommended for:
- Export shipments where ice must last 48+ hours without replenishment
- Multi-hub routes with 2–3 re-icing stops
- Tropical climates where ambient heat accelerates ice melt
For short-haul (6–12 h) and regional distribution, standard twin-wall construction is sufficient and lighter.
Is the ice cold seafood box food-contact certified?
ج: Yes. All PPBOXY ice cold boxes are manufactured from البولي بروبيلين المخصص للاستخدام الغذائي compliant with FDA 21 CFR 177.1520 (USA), EU Regulation 10/2011 (Europe), and GB 4806.7 (China). For ice cold applications specifically, our boxes pass immersion migration testing at 40°C for 10 days — far exceeding the 0–4°C real-world condition where meltwater is in continuous contact with both the product and box interior.
Can PPBOXY customize drain port positions for different seafood types?
ج: Yes. Drain port placement is customizable during die-cutting — not a post-manufacturing modification. Options include:
- Bottom-center single port — standard, suitable for whole fish
- Dual side ports — for large boxes with mixed loads
- Perforated base panel — for shellfish requiring full-base drainage
- Custom positions — specified by the buyer based on product and stacking orientation
