PP Corrugated Seafood Box — The Universal Packaging for Fish, Shellfish & Crustaceans
A Boîte en PP ondulé pour produits de la mer is a reusable, waterproof shipping container made from polypropylene hollow-sheet — purpose-built to replace disposable EPS styrofoam and waxed cardboard in every segment of the seafood supply chain. From wholesale fish markets to live-lobster export, from shrimp cold-chain warehouses to direct-to-consumer delivery, this one material platform eliminates the three chronic failures of traditional seafood packaging: moisture collapse, contamination risk, and single-use waste .
Unlike generic plastic crates, PP corrugated boxes combine the structural rigidity of twin-wall sheet with the fold-flat convenience of corrugated cardboard — at roughly one-third the weight of solid plastic equivalents. The result is a box that survives ice melt, resists bacterial growth, stacks 8–10 layers high in cold rooms, and folds flat for the return trip.

Why Seafood Demands Better Than Cardboard
Seafood is the only major food category where the packaging is expected to be soaking wet for the entire supply chain. Melted ice, fish slime, and saltwater spray make conventional cardboard — even wax-coated versions — degrade within hours. Waxed cardboard absorbs moisture at the seams; EPS foam cracks under stacking pressure and leaches microplastics. PP corrugated solves all three:
No moisture absorption — closed-cell polypropylene repels water permanentlyNo structural decay — twin-wall flutes maintain rigidity whether dry or submergedAucune libération de microplastiques — solid-sheet construction, not bead-based foam
Built for the Cold Chain: Ice-Melt Waterproof & Food-Safe
Every PP corrugated seafood box from PPBOXY is engineered for the conditions that destroy other packaging:

Key Features of PP Corrugated Seafood Boxes
Imperméable à l'eau de fonte et prêt pour le drainage
Seafood shipping means ice — and ice means meltwater. PP corrugated boxes are 100% étanche at every surface and seam. Optional integrated drain ports (pre-cut or custom-placed) let meltwater exit without opening the box, keeping product elevated and dry between ice top-ups. Unlike cardboard that absorbs meltwater into its walls, PP corrugated stays structurally identical whether the box is dry or sitting in 3 cm of ice water.
Food Contact Compliance (FDA / EFSA / EU 10/2011)

Seafood Industry Applications
Fish Processing & Auction Houses
In wholesale fish markets and processing plants, speed and hygiene are non-negotiable. PP corrugated fish boxes are hosed down between lots , stacked immediately, and returned to the line — no drying time, no cardboard waste, no contamination carryover. Their smooth inner walls prevent fish scales and blood from lodging in crevices, supporting HACCP compliance.
Shrimp & Shellfish Cold Chain
Shrimp and shellfish are among the most temperature-sensitive seafood. PP corrugated shrimp boxes maintain unbroken cold-chain integrity from dock to warehouse to retail, with insulated walls that slow ice melt by up to 30% compared to open-top EPS containers. Built-in drain ports prevent shrimp from sitting in meltwater — a critical quality factor for head-on product where waterlogging discolors shells.
Lobster & Crab Live Transport
Live crustaceans require controlled humidity and ventilation — not airtight insulation. PP corrugated lobster boxes feature precision ventilation holes that maintain oxygen flow while retaining enough moisture to keep gills wet during 24–48 h transit. The result: lower mortality rates compared to EPS coolers, which trap CO₂ and accelerate stress.
International Seafood Trade & Export
Export shipments face the harshest test: multi-modal transport (truck → port → ship → port → truck) over 5–21 days, with customs inspections, temperature fluctuations, and rough handling. PP corrugated seafood boxes are rated for de −20 °C à +80 °C , fold flat for container return, and comply with ISPM-15 exemption (solid plastic, no wood — no fumigation certificate needed).
Retail & E-Commerce Seafood Delivery
Direct-to-consumer seafood is the fastest-growing segment — and the most packaging-intensive per kilogram. PP corrugated boxes deliver the unboxing experience that EPS foam cannot: custom-printed branding, secure tamper-evident closures, and a reusable container the customer keeps for storage. No Styrofoam crumbs, no wax residue, no guilt.
Foire aux questions
What is a PP corrugated seafood box?
A: A PP corrugated seafood box is a reusable, waterproof shipping container made from polypropylene twin-wall sheet, designed specifically for seafood storage and transport. Unlike EPS styrofoam or waxed cardboard, it resists ice-melt submersion, stacks 8–10 layers high in cold rooms, and survives 50–200+ handling cycles — making it the most cost-effective and food-safe option for fish, shrimp, lobster, and shellfish distribution.
Is PP corrugated packaging safe for direct food contact with seafood?
A: Yes. All PPBOXY seafood boxes are manufactured from food-grade polypropylene compliant with FDA 21 CFR 177.1520 (USA), EU Regulation 10/2011 (Europe), and GB 4806.7 (China). Migration test reports and compliance certificates are available on request for import clearance and quality audits.
Which type of seafood box do I need — shrimp, fish, lobster, or general purpose?
A: It depends on your product and supply chain:
En quoi une boîte en PP ondulé pour produits de la mer diffère-t-elle d'une boîte en polystyrène expansé (EPS) ?
A: PP corrugated is waterproof, stackable to 8+ layers, reusable for 50–200+ cycles, and fully recyclable — EPS foam cracks under stacking, absorbs water at seams, is single-use, and is not widely recyclable. While PP corrugated costs more per unit, it breaks even after 10–15 trips and reduces total packaging cost by 40–60% over a 3-year contract. See the full comparison table ci-dessus.
Can PP corrugated seafood boxes withstand freezing temperatures?
A: Yes. PP corrugated maintains full structural flexibility from de −20 °C à +80 °C , covering all standard seafood cold-chain ranges including blast freezing, cold-room storage, and ambient loading docks. Unlike waxed cardboard, which delaminates under thermal cycling, PP corrugated shows zero degradation over 200+ freeze-thaw cycles.
Are PP corrugated seafood boxes foldable for return shipping?
A: Most PPBOXY seafood box models feature a fold-flat design that reduces return-shipping volume by 75–80%. One pallet of folded boxes replaces four pallets of rigid EPS crates — significantly cutting backhaul freight cost and storage space. Foldable models include integrated locking tabs; no tools required for assembly (typical setup: 10–15 seconds per box).
Quelles sont les options de personnalisation disponibles pour les coffrets de fruits de mer ?
A: PPBOXY offers full OEM/ODM customization: 300+ standard size molds or fully custom dimensions, 15+ stock colors plus Pantone matching for species/grade coding, screen or digital printing (Corona-treated surface for high-resolution graphics), and accessories including dividers, absorbent pads, RFID tags, and tamper-evident seals .
