TOPGREEN Launches Innovative 3.5 Gallon Rotomoulded Ice Cooler Box for Outdoor Enthusiasts
CHINA – A new level of durability and functionality has arrived in the outdoor gear market as TOPGREEN, a leading manufacturer of high-quality rotomoulded products, unveils its latest innovation — the 3.5 Gallon Rotomoulded Ice Cooler Box Bucket. Tailored for camping, fishing, and outdoor recreation, this compact but high-performance cooler box is set to redefine how adventurers store food and beverages on the go.
Crafted using rotational molding technology, the 3.5-gallon cooler is made from food-grade LLDPE (Linear Low-Density Polyethylene) and reinforced with PU insulation, making it capable of maintaining low temperatures for extended periods — perfect for long trips, fishing expeditions, or picnics. The box’s smart design and rugged build are attracting strong attention from outdoor enthusiasts, food transport businesses, and camping gear retailers.
Innovative Features Set the Cooler Apart
This rotomoulded cooler box stands out thanks to several user-centric features. It is equipped with a durable leak-proof sealing gasket that locks in cold air and prevents spills, ensuring reliable performance under tough conditions. A built-in relief valve helps users easily open the box when internal and external air pressures differ — a common challenge in traditional coolers.
Another highlight is the multifunctional stainless steel lock, which acts as a secure latch and a convenient bottle opener. For better organization, the cooler comes with a removable chopping board divider that separates contents and doubles as a food prep surface. Ergonomic nylon handles ensure comfortable transport, while anti-slip rubber feet provide extra stability, even on wet or uneven terrain.
Compact Yet Spacious
Though compact in size, the cooler’s internal dimensions (24.6×24.6×29.8CM) offer ample room for drinks, snacks, or freshly caught fish. The external dimensions (36.7×35.3×39.3CM) make it easy to store and transport. Whether used for outdoor dining or cold chain delivery, this cooler delivers reliable performance and convenience.
Designed with Sustainability and Versatility in Mind
The 3.5 Gallon Rotomoulded Ice Cooler Box is not only built for extreme conditions but is also environmentally conscious. The food-safe, BPA-free materials make it ideal for transporting perishable goods without contamination. TOPGREEN also offers OEM and private label services, giving brands the ability to customize coolers with logos, colors, or special features.
Meeting Global Demand
With a monthly production capacity of 5,000 units, TOPGREEN is ready to serve global markets. The company accepts orders starting from 50 units, and provides sample testing, quality assurance (SGS certified), and full OEM/ODM support.
As consumer interest in durable, multifunctional outdoor gear continues to rise, TOPGREEN’s new cooler box is well-positioned to meet demand with innovation and affordability.
