Product Details

The 140QT NL-140 has an interior of about 105 × 32 × 38 cm, and its more-than-one-meter usable length is the key advantage of this model. It is better suited to larger fish, longer catch and supplies for extended group trips, with a clear focus on offshore fishing, yachts and commercial leisure boats. The rotomolded body suits marine and dock environments and PU foam provides insulation. Logos, colors and packaging can be customized for marine brands and project orders.

More than one meter of usable internal length makes this model much better suited to larger and longer catch.

Suitable for camping, fishing, road trips, beach days, boating and other outdoor activities. Each capacity serves a different load, group size and handling requirement.

Suitable for outdoor brands, fishing channels, distributors and private-label programs. Different capacities can be combined into a range covering personal carry, family camping and large marine use.

OEM/ODM is available with custom logo, color and packaging options. Volume programs can be configured around the brand position and sales channel.

140QT Outdoor Portable Insulated Rotomolding Cooler Box — NL-140

Ningbo Nelgreen Outdoor Products Co., Ltd. manufactures the 140QT Outdoor Portable Insulated Rotomolding Cooler Box (model NL-140) for offshore fishing, yachts, commercial leisure boats, and extended group trips. This 140QT rotomolded cooler box is built with food-grade LLDPE and high-density PU foam insulation, delivering ice retention of up to 5–7 days under proper use. The defining feature is its usable internal length of more than one meter — approximately 105 × 32 × 938 cm — which accommodates larger fish, longer catch, and bulk supplies that standard coolers cannot hold.

As a 140QT Outdoor Portable Insulated Rotomolding Cooler Box supplier, we support marine brands, fishing channels, distributors, and private-label programs with OEM/ODM customization including logos, colors, and packaging. The rotomolded one-piece body resists saltwater, UV exposure, and impact, making it suitable for dock, deck, and beach environments.

Application Fit

The NL-140 is designed for scenarios where internal length is the critical dimension. Typical uses include:

  • Offshore fishing and long-range sportfishing — holds tuna, wahoo, and other large pelagic species without bending the tail.
  • Yacht and commercial leisure boat provisioning — stores bulk ice, drinks, and food for multi-day trips.
  • Seafood transport and dock-side holding — maintains temperature for fresh catch during unloading or short logistics.
  • Large group camping, beach parties, and tailgating — provides enough volume for 20+ people.

Construction and Materials

We rotomold the body and lid from food-grade LLDPE, which meets FDA and RoHS compliance. The rotational molding process produces a seamless, stress-free shell with uniform wall thickness. High-density polyurethane foam is injected between the inner and outer layers, providing thermal insulation without CFCs. The lid seals with a precision-molded gasket to minimize cold air loss.

UV-stabilized LLDPE resists cracking and fading in direct sunlight. The exterior is easy to clean and withstands saltwater, fuel, and fish slime. Stainless-steel or zinc-plated hardware is used for hinges and latches depending on the production batch.

Configuration and Customization

We offer the NL-140 as a standard model and support full OEM/ODM modifications:

  • Color — any RAL or Pantone match; standard white, blue, gray, or green.
  • Logo — pad printing, hot stamping, or in-mold labeling.
  • Accessories — drain plug type, tie-down points, divider trays, and non-slip feet.
  • Packaging — single-blow carton, polybag, or custom retail-ready box.
  • Structural modifications — handle placement, lid hinge reinforcement, or added wheel mounts (note: the 140QT is a carry model; wheeled options are available in our 240QT large capacity sea fishing Rotomolding cooler box).

Quality Assurance and Compliance

Every NL-140 is manufactured under our ISO 9001 quality management system. We conduct the following checks before shipment:

  • Visual inspection for surface defects, flash, and color consistency.
  • Dimensional verification of internal and external profiles.
  • Leak test on drain plug and lid seal.
  • Insulation performance sample test (temperature retention over 24 h).
  • Drop test from 1 m on concrete (LLDPE impact resistance).

Our products comply with BSCI, SGS, RoHS, and FDA standards. Factory verification is registered on Alibaba.

Installation, Handling, and Maintenance

The 140QT cooler box requires no on-site installation. It is ready to use out of the carton. For marine applications, we recommend securing the box with straps or brackets to prevent shifting in rough seas. The drain plug should be opened periodically to release meltwater. Clean with mild soap and water; avoid abrasive cleaners that may dull the surface. Store with the lid slightly ajar to prevent odor buildup. Replace the drain plug gasket if leakage occurs.

Frequently Asked Questions

Q: What is the actual usable internal length of the 140QT cooler?
A: The internal length is approximately 103 cm (40.6 in), with a usable floor length of about 105 cm when measured at the base. This allows storage of fish up to 1 m without bending.

Q: Can the 140QT be used on a boat without sliding?
A: The bottom is flat with a textured surface. For offshore use, we recommend adding non-slip pads or strapping the box to a deck cleat. We can integrate tie-down slots on request.

Q: How long does ice last in the NL-140?
A: Under typical summer conditions (30–35 °C ambient, minimal lid opening), a full load of block ice can last 5–7 days. Actual performance depends on ice quantity, ambient temperature, and usage frequency.

Q: What is the minimum order quantity for OEM customization?
A: MOQ for custom color and logo is typically 100–300 pcs depending on complexity. Standard black/white models can be ordered in smaller quantities. Contact us for project-specific MOQ.

Q: Does the 140QT come with a drain plug?
A: Yes, a threaded drain plug is installed at the lower end of the box. The plug is removable for draining meltwater. We can supply a hose adapter for continuous drainage on boats.

Q: Is the LLDPE material food-grade?
A: Yes, we use food-grade LLDPE that complies with FDA and EU food contact regulations. The material is odor-free and does not transfer taste to stored contents.
