Lobster Boxes — The Box That Ships a Live Animal, Not Just a Product
Every other box in PPBOXY’s seafood range handles dead product — fresh fish fillets on ice, frozen shrimp at −18°C, chilled scallops in sealed trays. Lobster boxes handle a living animal that must arrive at the restaurant or market alive, undamaged, and vigorous. A dead lobster is a 100% loss.
This changes every packaging requirement. The box must retain moisture — lobsters are shipped packed in damp newspaper or seaweed, and gills must stay wet for the animal to breathe. The box must withstand wet stacking — damp newspaper transfers moisture to the box walls, and the entire pallet travels at 0–4°C with near-saturated humidity. The box must protect lobsters from each other — claws can crush adjacent lobsters in transit if the animals are not separated; a single damaged lobster in a box can trigger aggressive behavior that cascades through the entire shipment.
PPBOXY’s lobster box is fabricated from twin-wall corrugated polypropylene that delivers all three requirements simultaneously. Waterproof walls do not soften from the damp newspaper packing. The rigid structure maintains divider integrity even when the box walls are wet from condensation. And the PP material withstands the 0–4°C cold chain without embrittlement — boxes can be moved between the refrigerated truck, the walk-in cooler, and the restaurant receiving dock without cracking or structural failure.

The Three Challenges of Live Lobster Transport — and How PP Solves Them
Challenge 1: Moisture Without Structural Failure
Live lobsters are packed in damp newspaper or seaweed to keep gills moist during transport. This packing medium transfers moisture continuously to the box walls for the entire trip — typically 12–36 hours from Nova Scotia to a Manhattan restaurant, or from a Maine wharf to a Los Angeles distributor. Waxed cardboard absorbs moisture gradually through wax imperfections and loses 40–60% of its compression strength within 12 hours of damp contact. PP absorbs less than 0.01% water — the box walls are bone-dry internally regardless of how wet the newspaper packing becomes.
Challenge 2: Claw Damage Prevention
Lobsters are aggressive in confined spaces. An unrestrained lobster will attack adjacent lobsters, crushing claws and antennae. Damaged lobsters release stress hormones that trigger aggression in neighboring lobsters — a cascade effect that can ruin an entire shipment. The solution is physical separation: PP dividers inside the box create individual compartments, and elastic band anchor points hold claws in a closed position. Unlike cardboard dividers that soften from moisture and collapse, PP dividers maintain their shape and position for the duration of the trip.
Challenge 3: Wet-Stack Compression
Lobster boxes travel stacked 6–8 high on pallets in refrigerated trucks at 0–4°C and > 90% relative humidity. The bottom box in the stack supports 100–175 kg of static load — while its walls are wet from condensation and its contents are shifting live animals. Waxed cardboard under these conditions fails progressively: the bottom boxes soften, compress, and eventually collapse, crushing the lobsters inside. PP boxes maintain full compression strength in this environment — the box at the bottom of the pallet is mechanically identical to the box at the top.

Lobster Supply Chain — From Trap or Wharf to Restaurant Kitchen
Stage 1: Harvest & Primary Packing (Hour 0–4)
Lobsters are landed at the wharf or processing facility, graded by weight (chicken 1 lb, quarter 1.25 lb, half 1.5 lb, select 1.75–2.5 lb, jumbo 3+ lb), and packed into PP boxes with damp newspaper or seaweed. Claws are banded. Internal dividers separate lobsters by size or individually. Boxes are stacked on pallets.
Stage 2: Refrigerated Transport (Hour 4–36)
Pallets are loaded into refrigerated trucks at 0–4°C. The lobster box’s rigid PP walls prevent crushing during transport vibration. Moisture from the damp packing is contained within the box — condensation does not soften the walls. Drivers can stack 6–8 high without bottom-box collapse risk.
Stage 3: Distribution Center / Wholesale (Hour 12–48)
At the distribution center, pallets are broken down and individual boxes may be re-sorted by destination. The PP box is clean, dry externally (regardless of internal dampness), and professional in appearance — important for wholesale buyers who inspect product on arrival.
Stage 4: Restaurant / Retail Receiving (Hour 24–72)
The box arrives at the restaurant or seafood market. The chef or fishmonger opens a clean, intact box — not a water-stained, collapsing cardboard mess. Lobsters are removed alive and vigorous. The box is washed, sanitized, and returned to the supplier for the next shipment.

Foire aux questions
Q: Can lobsters really be shipped in a PP box instead of a waxed cardboard box?
Yes — and many lobster distributors are making the switch. The PP box outperforms waxed cardboard in every dimension relevant to live lobster transport: waterproof structure maintains integrity in damp conditions, rigid dividers prevent claw damage, and stackable design eliminates bottom-box collapse risk. The initial cost is higher, but at 30–50 reuse cycles, the per-trip cost drops to a fraction of single-use waxed cardboard.
Q: How do you keep lobsters alive during transport in a PP box?
Live lobsters are packed with damp newspaper or seaweed to keep gills moist, and the boxes travel in a refrigerated truck at 0–4°C. The PP box walls are non-porous and trap humidity around the lobsters — maintaining the moist environment their gills require. The box is not airtight (lobsters can survive extended periods without water as long as gills remain moist), but optional small ventilation slots can be added for air exchange on long-haul shipments.
Q: How do you prevent lobsters from damaging each other in the box?
Three methods, all compatible with PPBOXY’s lobster boxes: (1) Claw bands — elastic bands placed over each claw before packing, the industry standard for wholesale lobster transport. (2) Internal dividers — fixed PP partitions create individual compartments so lobsters cannot reach each other. (3) Combination — bands plus dividers for maximum-value shipments (jumbo lobsters, live export). PPBOXY can integrate elastic band anchor points into the divider walls for secure band attachment during transport.
Q: Can the boxes be washed and reused?
Yes. PP is non-porous and compatible with seafood-grade sanitizers. After each trip, wash the box and dividers with a standard seafood processing sanitizer (peroxyacetic acid, quaternary ammonium), rinse, and air-dry. The box is ready for its next shipment. Waxed cardboard, by contrast, is single-use — it cannot be washed because the material absorbs water and cleaning chemicals.
Q: What sizes are available for different lobster grades?
Standard boxes accommodate the full range of commercial lobster sizes — from 1 lb chickens to 5+ lb jumbos. Box height and divider spacing are configured to your typical product mix. Common configurations: 600×400 mm box with 8–12 compartments for half/select lobsters (1.5–2.5 lb), 800×600 mm box with 12–20 compartments for chicken/quarter lobsters (1–1.5 lb), or large-format bulk boxes for jumbo lobsters (3+ lb, 4–6 per box). Contact us with your typical grade distribution for a configuration recommendation.
Q: What is the minimum order quantity?
We do not impose a minimum order requirement. Our production capabilities accommodate a wide spectrum of order volumes — from prototype sampling and small-batch testing to full-scale mass production — allowing us to align with your specific project needs at every stage.
