Description
SUNMORE ROTO OEM Custom 31L Rotomolded Insulated Cooler Box is a large-capacity commercial thermal container designed for catering, seafood, and cold chain transport applications. Manufactured using one-piece seamless rotational molding technology, this food-grade LLDPE waterproof thermal storage box ensures reliable performance in demanding environments.

This 31L insulated cooler box features a thick food-contact LLDPE outer shell and full high-density PU foam insulation interlayer. Equipped with sturdy stainless steel spring latches and full-circle silicone sealing gaskets, the box offers full spacious inner space without internal partitions for bulk food and seafood storage. The integrated rotomolded body provides excellent shock resistance and leak-proof performance, while the thick foam layer delivers long-duration temperature preservation.

  • Food-Grade Thickened LLDPE Material: Safe, non-toxic, and corrosion-resistant material that withstands seawater, fruit acid, and food sauces without harmful precipitation.
  • Full PU Foam Insulation Interlayer: High-density polyurethane foam creates an airtight thermal barrier, maintaining stable temperatures for 8-12 hours under normal ambient conditions.
  • Heavy-Duty Stainless Steel Latches: Robust spring buckles and full-circle food-grade silicone gaskets ensure tight sealing to minimize temperature loss.
