18QT Car Small Rotomolding Cooler Box – NL-18

As a 18qt Car Small Rotomolding Cooler Box.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 18QT Car Small Rotomolding Cooler Box for buyers who need a compact, durable insulated container that fits easily in a car trunk, boat locker, or campsite. This model, designated NL-18, bridges the gap between a personal lunch cooler and a full-size family box. It is rotomolded from food-grade LLDPE with high-density PU foam insulation, giving it the structural toughness and thermal performance required for repeated outdoor use.

We supply this cooler to outdoor brands, fishing channels, distributors, and private-label programs. Each unit is produced in our Ningbo factory under ISO 9001 and BSCI quality systems, with SGS, RoHS, and FDA compliance available per project. The 18QT capacity is ideal for a full day at the beach, recreational fishing, road trips, or small-family outings where ice retention of up to 5–7 days is achievable under proper conditions.

Construction and Materials

The NL-18 uses a one-piece rotomolded LLDPE shell with no seams or weak points. This process produces a thick, impact-resistant wall that withstands drops, UV exposure, and saltwater environments. The insulation layer is high-density polyurethane (PU) foam, injected between the inner and outer walls to minimize thermal transfer. The lid seals tightly with a gasket to prevent cold air loss.

  • Material: Food-grade LLDPE (linear low-density polyethylene) – FDA compliant for direct food contact.
  • Insulation: High-density PU foam, CFC-free.
  • Molding: Rotational molding (roto-molding) – uniform wall thickness, no internal stress points.
  • UV Resistance: UV-stabilized resin for prolonged outdoor use.

Application Fit and Target Use

The 18QT size is designed for day trips where portability and moderate capacity are priorities. Typical applications include:

  • Car travel and road trips – fits behind a seat or in a trunk without sacrificing passenger space.
  • Beach and picnic outings – holds drinks, sandwiches, and ice for 4–6 people for a full day.
  • Recreational fishing – keeps bait and catch cool on small boats or shore fishing.
  • Boating and kayaking – compact enough for limited deck space.
  • Tailgating and sporting events – easy to carry with the integrated handle.

This model is also suitable for brand owners who want to offer a starter size in a cooler lineup. We can combine the NL-18 with larger models such as the 60QT Outdoor Rotomolding Cooler Box or the 55L Portable Insulated Rotomolding Cooler Box for a full range.

Information We Use to Configure Your Solution

To prepare a quotation and production plan for the NL-18, we need the following project details:

  • Quantity: Target order volume per shipment and annual forecast.
  • Customization: Logo type, color code (Pantone/RAL), and packaging format.
  • Target Market: Region and applicable compliance requirements (e.g., FDA for US, EU food contact).
  • Delivery Timeline: Required date and shipping port preference (Ningbo/Shanghai).
  • Budget Range: Target unit price to help us recommend the most cost-effective configuration.
  • Sample Request: Stock samples are available for evaluation; custom samples require mold setup time.

Maintenance and Serviceability

The NL-18 requires minimal maintenance. Clean the interior and exterior with mild soap and water after each use. Avoid abrasive cleaners that may scratch the LLDPE surface. The lid hinge and latch are mechanical and do not require lubrication. If the drain plug (optional) is fitted, check the O-ring annually and replace if worn. Spare parts such as latches, plugs, and gaskets are available from our warehouse.
