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:\u00a0<strong>moisture collapse, contamination risk, and single-use waste<\/strong>.<\/p>\n<p>Unlike generic plastic crates, PP corrugated boxes combine the structural rigidity of twin-wall sheet with the fold-flat convenience of corrugated cardboard \u2014 at roughly one-third the weight of solid plastic equivalents. The result is a box that survives ice melt, resists bacterial growth, stacks 8\u201310 layers high in cold rooms, and folds flat for the return trip.<\/p>\n<h2>Specifications<\/h2>\n<table>\n<thead>\n<tr>\n<th>Attribute<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Material<\/td>\n<td>Polypropylene (PP) corrugated hollow sheet<\/td>\n<\/tr>\n<tr>\n<td>Food Contact Grade<\/td>\n<td>FDA 21 CFR 177.1520 \/ EU 10\/2011 \/ GB 4806.7<\/td>\n<\/tr>\n<tr>\n<td>Wall Type<\/td>\n<td>Twin-wall fluted sheet<\/td>\n<\/tr>\n<tr>\n<td>Sheet Thickness<\/td>\n<td>3 mm, 4 mm, 5 mm (custom 2\u201312 mm)<\/td>\n<\/tr>\n<tr>\n<td>Rango de temperatura<\/td>\n<td>\u221220 \u00b0C to +80 \u00b0C<\/td>\n<\/tr>\n<tr>\n<td>Waterproof Rating<\/td>\n<td>100% waterproof (closed-cell PP)<\/td>\n<\/tr>\n<tr>\n<td>Stack Height<\/td>\n<td>8\u201310 layers (standard), 4\u20136 layers (live product)<\/td>\n<\/tr>\n<tr>\n<td>Reusability<\/td>\n<td>50\u2013200+ cycles depending on duty level<\/td>\n<\/tr>\n<tr>\n<td>Fold-Flat Volume Reduction<\/td>\n<td>75\u201380%<\/td>\n<\/tr>\n<tr>\n<td>Drainage<\/td>\n<td>Optional integrated drain ports (pre-cut or custom)<\/td>\n<\/tr>\n<tr>\n<td>Ventilation<\/td>\n<td>Optional precision ventilation holes (lobster\/crab models)<\/td>\n<\/tr>\n<tr>\n<td>Standard Sizes<\/td>\n<td>400\u00d7300\u00d7150 mm to 1200\u00d7800\u00d7400 mm<\/td>\n<\/tr>\n<tr>\n<td>Tama\u00f1os personalizados<\/td>\n<td>Available (300+ standard molds + fully custom)<\/td>\n<\/tr>\n<tr>\n<td>Colors<\/td>\n<td>15+ stock colors; custom Pantone matching<\/td>\n<\/tr>\n<tr>\n<td>Impresi\u00f3n<\/td>\n<td>Screen print (standard) \/ digital print (Corona-treated)<\/td>\n<\/tr>\n<tr>\n<td>Accessories<\/td>\n<td>Dividers, absorbent pads, RFID tags, tamper-evident seals<\/td>\n<\/tr>\n<tr>\n<td>ISPM-15<\/td>\n<td>Exempt (solid plastic, no wood content)<\/td>\n<\/tr>\n<tr>\n<td>Reciclabilidad<\/td>\n<td>100% PP recyclable<\/td>\n<\/tr>\n<tr>\n<td>Cantidad m\u00ednima de pedido<\/td>\n<td>Contact for details<\/td>\n<\/tr>\n<tr>\n<td>Certifications<\/td>\n<td>FDA \/ EFSA \/ EU 10\/2011 \/ GB 4806.7 \/ ISO 9001<\/td>\n<\/tr>\n<tr>\n<td>Plazo de entrega<\/td>\n<td>7\u201315 business days (standard); 3\u20135 days (stock sizes)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Why Seafood Demands Better Than Cardboard<\/h3>\n<p>Seafood is the only major food category where the packaging is\u00a0<em>expected<\/em>\u00a0to be soaking wet for the entire supply chain.

PP corrugated boxes are\u00a0<strong>100% waterproof<\/strong>\u00a0at every surface and seam. Optional\u00a0<strong>integrated drain ports<\/strong>\u00a0(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.<\/p>\n<h3>Food Contact Compliance (FDA \/ EFSA \/ EU 10\/2011)<\/h3>\n<p>All PPBOXY seafood boxes are manufactured from\u00a0<strong>food-grade polypropylene<\/strong>\u00a0compliant with:<\/p>\n<ul>\n<li><strong>FDA 21 CFR 177.1520<\/strong>\u00a0\u2014 Olefin polymers for food contact (USA)<\/li>\n<li><strong>EU Regulation 10\/2011<\/strong>\u00a0\u2014 Plastic materials in contact with food (Europe)<\/li>\n<li><strong>EFSA migration limits<\/strong>\u00a0\u2014 Specific and total migration within safe thresholds<\/li>\n<li><strong>GB 4806.7<\/strong>\u00a0\u2014 Food contact plastics (China domestic standard)<\/li>\n<\/ul>\n<p>Documentation and compliance certificates are available on request for import clearance and audit trails.<\/p>\n<h3>50\u2013200+ Cycle Reusability<\/h3>\n<table>\n<thead>\n<tr>\n<th>Usage Intensity<\/th>\n<th>Estimated Cycle Life<\/th>\n<th>Comprador t\u00edpico<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Light duty (retail display)<\/td>\n<td>150\u2013200+ cycles<\/td>\n<td>Supermarkets, fish counters<\/td>\n<\/tr>\n<tr>\n<td>Medium duty (regional distribution)<\/td>\n<td>80\u2013150 cycles<\/td>\n<td>Wholesalers, restaurant suppliers<\/td>\n<\/tr>\n<tr>\n<td>Heavy duty (export + cold chain)<\/td>\n<td>50\u201380 cycles<\/td>\n<td>International traders, shrimp processors<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Even at 50 cycles, the per-trip cost of a PP corrugated seafood box is\u00a0<strong>70\u201385% lower<\/strong>\u00a0than a single-use EPS equivalent.<\/p>\n<h3>Custom Sizes, Colors &amp; Branding<\/h3>\n<table>\n<thead>\n<tr>\n<th>Customization<\/th>\n<th>Options<\/th>\n<th>Typical Use<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Tama\u00f1o<\/td>\n<td>300+ standard molds; fully custom dimensions<\/td>\n<td>Species-specific packing<\/td>\n<\/tr>\n<tr>\n<td>Color<\/td>\n<td>15+ stock colors; custom Pantone match<\/td>\n<td>Species\/grade color coding<\/td>\n<\/tr>\n<tr>\n<td>Impresi\u00f3n<\/td>\n<td>Screen print (standard) \/ digital (Corona-treated)<\/td>\n<td>Logo, handling icons, traceability codes<\/td>\n<\/tr>\n<tr>\n<td>Accessories<\/td>\n<td>Dividers, absorbent pads, RFID tags, tamper-evident seals<\/td>\n<td>Multi-product lots, export compliance<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Stackable &amp; Foldable Designs<\/h3>\n<ul>\n<li><strong>Stackable<\/strong>: Reinforced corners and flat rims enable\u00a0<strong>8\u201310 layer stacking<\/strong>\u00a0in cold rooms without compression damage to contents below.<\/li>\n<li><strong>Foldable<\/strong>: Return-trip volume reduction of\u00a0<strong>75\u201380%<\/strong>\u00a0\u2014 one pallet of folded boxes replaces four pallets of rigid crates, cutting return freight cost dramatically.<\/li>\n<\/ul>\n<h3>\u00a0Seafood Industry Applications<\/h3>\n<h3>Fish Processing &amp; Auction Houses<\/h3>\n<p>In wholesale fish markets and processing plants, speed and hygiene are non-negotiable. PP corrugated fish boxes are\u00a0<strong>hosed down between lots<\/strong>, stacked immediately, and returned to the line \u2014 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.<\/p>\n<h3>Shrimp &amp; Shellfish Cold Chain<\/h3>\n<p>Shrimp and shellfish are among the most temperature-sensitive seafood. PP corrugated shrimp boxes maintain\u00a0<strong>unbroken cold-chain integrity<\/strong>\u00a0from 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 \u2014 a critical quality factor for head-on product where waterlogging discolors shells.<\/p>\n<h3>Lobster &amp; Crab Live Transport<\/h3>\n<p>Live crustaceans require\u00a0<strong>controlled humidity and ventilation<\/strong>\u00a0\u2014 not airtight insulation. PP corrugated lobster boxes feature\u00a0<strong>precision ventilation holes<\/strong>\u00a0that maintain oxygen flow while retaining enough moisture to keep gills wet during 24\u201348 h transit. The result: lower mortality rates compared to EPS coolers, which trap CO\u2082 and accelerate stress.<\/p>\n<h3>International Seafood Trade &amp; Export<\/h3>\n<p>Export shipments face the harshest test:\u00a0<strong>multi-modal transport (truck \u2192 port \u2192 ship \u2192 port \u2192 truck)<\/strong>\u00a0over 5\u201321 days, with customs inspections, temperature fluctuations, and rough handling. PP corrugated seafood boxes are rated for\u00a0<strong>\u221220 \u00b0C to +80 \u00b0C<\/strong>, fold flat for container return, and comply with ISPM-15 exemption (solid plastic, no wood \u2014 no fumigation certificate needed).<\/p>\n<h3>Retail &amp; E-Commerce Seafood Delivery<\/h3>\n<p>Direct-to-consumer seafood is the fastest-growing segment \u2014 and the most packaging-intensive per kilogram. PP corrugated boxes deliver the\u00a0<strong>unboxing experience<\/strong>\u00a0that 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.<\/p>\n<h2>Preguntas frecuentes<\/h2>\n<h4>What is a PP corrugated seafood box?<\/h4>\n<p><strong>A:<\/strong>\u00a0A 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\u201310 layers high in cold rooms, and survives 50\u2013200+ handling cycles \u2014 making it the most cost-effective and food-safe option for fish, shrimp, lobster, and shellfish distribution.<\/p>\n<h4>Is PP corrugated packaging safe for direct food contact with seafood?<\/h4>\n<p><strong>A:<\/strong>\u00a0Yes. 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).
