28L Rotomolded Cooler Box Portable Outdoor Ice Chest Food Grade LLDPE Camping Fishing Cooler

This 28L Rotomolded Cooler Box is engineered for outdoor enthusiasts who demand dependable ice retention in a truly portable package. Manufactured through the rotational molding process, the cooler features a seamless one-piece LLDPE body that eliminates weak points found in injection-molded alternatives. The food-grade linear low-density polyethylene shell is reinforced with high-density PU foam insulation, delivering up to 7 days of ice preservation under normal summer conditions. Whether you are planning a weekend fishing trip, a family camping excursion, or a long day on the water, this portable ice chest keeps beverages chilled and perishables fresh without requiring an external power source. As a factory-direct rotomolded cooler box manufacturer, we control every stage of production to guarantee consistent wall thickness, superior impact resistance, and a finish that withstands years of heavy outdoor use.

• One-Piece Rotomolded Construction: The seamless LLDPE shell is formed in a single rotational molding cycle, creating a cooler box with no joints, no seams, and no weak points that could leak or crack under stress.
• High-Density PU Foam Insulation: The thick polyurethane foam core locks in cold temperatures, keeping ice for up to 7 days and maintaining safe food temperatures even in direct summer sunlight.
• Food-Grade Safe Materials: The interior liner is made from FDA-compliant food-grade LLDPE, free from BPA and other harmful chemicals, making it safe for direct contact with food, beverages, and ice.
• UV-Stabilized Weather Resistance: The exterior shell is treated with UV stabilizers to prevent fading, chalking, and brittleness caused by prolonged sun exposure during outdoor storage.
• Ergonomic Carry Handle: The sturdy integrated handle is molded into the body for a comfortable, balanced grip even when the cooler is fully loaded with ice and drinks.
• Leak-Proof Lid Seal: The gasketed lid forms a tight seal that prevents cold air from escaping and keeps meltwater inside, protecting your vehicle or boat from mess.
• Stackable and Space-Saving: The flat lid and tapered body allow multiple coolers to stack securely, maximizing storage efficiency in trucks, garages, and retail displays.
