NL330L Rotomolded Plastic Insulated Fish Tub for Seafood Storage

NL330L Rotomolded Plastic Insulated Fish Tub – Medium-Batch Seafood Handling

As a Nl330l Rotomolded Plastic Insulated Fish Tub For Seafood Storage.html manufacturer, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

Ningbo Nelgreen Outdoor Products Co., Ltd. manufactures the NL330L Rotomolded Plastic Insulated Fish Tub for Seafood Storage, a purpose-built container for dockside sorting, processing-plant staging and cold-chain transport of medium seafood batches. As a dedicated NL330L Rotomolded Plastic Insulated Fish Tub for Seafood Storage manufacturer, we combine food-grade LLDPE rotomolding with high-density PU foam insulation to deliver reliable thermal performance in wet, salt-laden environments. The 330-litre capacity bridges the gap between compact 220L tubs and bulk 660L containers, giving you commercial carrying volume without sacrificing floor space.

This model is specified by seafood processors, fishing ports, aquaculture operations and cold-chain logistics teams that handle whitefish, lobster, shrimp and other fresh products from vessel landing to processing or distribution. Optional caster wheels simplify repositioning on wet decks and plant floors. Custom colors, logos and project-specific configurations are supported through our OEM/ODM program.

Key Specifications

Application Fit and Workflow Integration

The NL330L is designed for operations that process medium-volume catches – typically 200–400 kg per batch depending on product density. Its internal footprint (92 × 685 cm) accommodates whole fish, fillets, lobster and shrimp with enough depth for ice layering. Common use cases include:

• Dockside sorting – after vessel landing, the tub receives catch for grading and icing before transfer to processing or cold storage.
• Processing-plant staging – holds product between cleaning, filleting and packing lines.
• Cold-chain transport – stacks efficiently in refrigerated trucks or containers for regional distribution.
• Aquaculture harvest – suitable for temporary holding of farmed fish or shellfish during harvest operations.

Optional caster wheels allow the tub to be moved easily across wet floors, reducing manual lifting. The smooth interior surface and rounded corners simplify cleaning and sanitation between batches.

Material and Construction Quality

Every NL330L tub is rotomolded from food-grade LLDPE (linear low-density polyethylene) in a single-piece construction, eliminating weld lines and weak points. The material is UV-stabilised for outdoor exposure and resists impact, corrosion and chemical cleaning agents. High-density polyurethane foam is injected between the inner and outer walls, providing consistent insulation that maintains internal temperature for extended periods under normal operating conditions.

Our factory in Yuyao, Ningbo, operates under quality management systems aligned with BSCI, ISO 9001, SGS, RoHS and FDA standards. Each production batch is inspected for dimensional accuracy, wall thickness uniformity and foam integrity before release.

Configuration Options and Customisation

We offer the NL330L in standard white/blue, with the following project-level customisations available through our OEM/ODM service:

• Color – any RAL or Pantone match for brand identity.
• Logo – in-mold or pad-printed logos, text or graphics.
• Caster configuration – two fixed + two swivel, with or without brakes; wheel diameter options for rough or smooth surfaces.
• Drain plug – standard or lockable drain for meltwater management.
• Lid attachment – hinged or removable lid; custom latch or seal options.
• Stacking features – lid recess and base ribs for stable stacking during transport.

For volume orders, we can also adjust wall thickness or add reinforcement ribs based on your handling equipment (forklift pockets, pallet jack clearance).

Installation, Maintenance and Serviceability

The NL330L requires no on-site installation – it is ready for immediate use upon delivery. For caster-equipped units, the wheels are pre-mounted or supplied with simple bolt-on brackets. Cleaning is straightforward: rinse with potable water and mild detergent; avoid abrasive tools that could damage the interior surface. The drain plug (if fitted) allows meltwater to be emptied without tilting the tub.

Spare parts – including replacement casters, drain plugs and lid hinges – are available from our warehouse. We maintain a 24-hour response time for technical inquiries and can arrange remote or on-site support for large-scale projects.

Quality Assurance and Compliance

Each NL330L tub is produced under documented quality control procedures. Key checks include:

• Raw material certificate of analysis (food-grade LLDPE).
• In-process wall thickness measurement (minimum 4 mm nominal).
• Foam density and adhesion test per batch.
• Dimensional verification against drawing.
• Load test (stacked configuration) for transport safety.

Our products comply with FDA food-contact requirements and RoHS restrictions. Third-party testing reports (SGS, Intertek) can be provided upon request for specific projects.
