The SUNMORE Custom Rotomolded HDPE Insulated Cooler Box is an integrated seamless rotomolded fresh storage solution manufactured by SUNMORE's professional rotomolding facility. Featuring a thickened one-piece HDPE rotational molding shell with high-density PU foam insulation interlayer, this cooler delivers exceptional cold retention performance. Equipped with double heavy-duty elastic lock buckles and full surrounding food-grade silicone sealing strip, the box provides excellent waterproof, leakproof, and dustproof capabilities. Ideal for outdoor camping, beach picnics, self-driving travel, offshore fishing, and seafood short-distance cold chain delivery. OEM customization services available for outer shell colors.
Key Features & Benefits
One-Piece Seamless Construction: Integrally rotomolded without splicing gaps, thick double-layer hollow wall prevents melted ice water seepage. Full surrounding silicone strip creates a completely sealed interior space, protecting contents from rainwater and dust during outdoor transport.
Superior Thermal Insulation: High-density closed-cell polyurethane thermal insulation foam effectively isolates internal and external heat exchange. Maintains ice frozen for multiple days under normal outdoor temperatures, meeting extended camping, fishing, and travel fresh-keeping requirements.
Durable Locking System: Two thickened anti-break elastic rubber latches symmetrically installed on both sides tightly compress the sealing strip to minimize cold air loss. High-strength engineering plastic construction withstands frequent opening and closing without fracture or deformation.
Customizable Appearance: Multiple mainstream solid colors available in stock. Custom outer shell color options available to match market positioning and brand style requirements.
Rugged Outdoor Durability: Thickened anti-impact modified rotomolded HDPE plastic shell offers strong toughness and compression resistance. Withstands bumping, dropping, and ultraviolet aging in challenging outdoor environments including beaches, fishing grounds, and mountain camps.
What customization service can be provided for this rotomolded insulated cooler box?
We support customizing the solid color of the cooler outer shell. The mold size, internal structure, and volume are fixed specifications and cannot be modified.
Can this cooler box keep ice frozen for several days outdoors?
Full high-density closed-cell PU foam is filled in the interlayer. Under normal outdoor temperatures, ice can stay frozen for multiple days to satisfy extended outdoor fresh-keeping needs.
Will melted ice water leak out when tilting the cooler box during carrying?
Integral seamless rotomolded box body matched with full surrounding silicone sealing strip effectively prevents ice water leakage when tilting or moving the cooler.
