55L Portable Insulated Rotomolding Cooler Box

Product Specifications

Application Fit and Configuration

The NL-55 fits between compact personal coolers and large marine boxes. Its interior dimensions (55 × 31 × 32 cm) accommodate weekend camping supplies, group beverages, fishing catch, and road trip provisions. The rotomolded construction with PU foam provides ice retention of up to 5–7 days under typical use, depending on ambient temperature, ice quantity, and opening frequency.

We offer OEM/ODM configuration: custom logos, colors, and packaging can be applied to match brand identity and channel requirements. Volume programs can combine the NL-55 with other capacities in our range—such as the 60QT Outdoor Rotomolding Cooler Box or 50QT Outdoor Fishing Rotomolding Cooler Box—to create a tiered product line.

Key Features

• Rotomolded LLDPE shell – seamless, impact-resistant, UV-stabilized for outdoor exposure.
• High-density PU foam insulation – minimizes thermal transfer, supports multi-day ice retention.
• Balanced medium-large capacity – 55L internal volume suits groups of 4–6 people.
• Distributor-friendly dimensions – efficient container loading (262 pcs/20 ft) reduces shipping cost per unit.
• Customization ready – mold design, logo embossing/debossing, color matching, and packaging options.

Quality Assurance and Compliance

Our factory operates under a quality management system aligned with BSCI, ISO 9001, SGS, RoHS, FDA, and Alibaba Factory Verification. Each production batch undergoes incoming material inspection, in-process monitoring, and final functional testing. We use food-grade LLDPE that meets FDA contact standards, and the PU foam is CFC-free.

Installation, Maintenance, and Service

The NL-55 requires no on-site installation. It is ready for immediate use after unpacking. Maintenance involves periodic cleaning with mild soap and water; avoid abrasive cleaners. The drain plug (if equipped) should be checked for debris. Spare parts such as handles, latches, and drain plugs are available through our after-sales team. We provide a 24-hour rapid response service for technical inquiries and warranty support.
