Product Description

Custom Rotomolded Insulated Cooler Box

Heavy-duty seamless rotomolded thermal insulation container designed for outdoor camping, fishing, picnics, and cold chain storage applications.

Product Overview

This premium insulated cooler box features a seamless rotomolded construction using thick food-grade LLDPE material. The one-time rotational molding process eliminates splicing gaps, while high-density PU foam insulation ensures excellent long-lasting ice retention. Equipped with elastic rubber sealing latches and integrated portable side handles, the cooler offers full waterproof sealing, shock resistance, corrosion resistance, and easy cleaning. Ideal for outdoor camping, sea fishing, beach picnics, fresh food transportation, medical cold chain storage, and vehicle-mounted refrigeration.

Key Features & Benefits

Integral Seamless Rotomolded Shell: One-step rotomolding creates a unified thick plastic shell with outstanding compression and drop resistance, capable of withstanding rough outdoor conditions without cracking or deformation.
Superior Ice Retention: Thick food-safe LLDPE outer shell combined with full-layer high-density PU thermal insulation foam effectively isolates external heat, extending ice retention time for days in high-temperature environments.
100% Waterproof & Air-Tight: Elastic rubber buckles and full surrounding silicone sealing strips ensure complete waterproof protection, preventing water ingress and ice melting during beach or boat use.
Corrosion Resistant & Easy Cleaning: PE material resists seawater, salt, and food oil corrosion. Smooth seamless surfaces allow simple water flushing without residual odors or stubborn stains.
Customization Options: Multiple standard capacities available with custom colors including grey, black, green, and army green. Optional accessories include internal partitions, drain plugs, cup holders, and non-slip foot pads.

We purchase full range tapered rotomolded barrels from 50L to 5000L to match diversified raw material storage of our integrated chemical factory. The tapered design facilitates complete material pouring without leftover residue, seamless one-piece PE structure prevents leakage of granular and mild corrosive liquid raw materials.
