Rotomolded Insulated Cooler Box
Built using rotational molding with double-wall construction and injected polyurethane foam insulation, our coolers deliver superior ice retention of up to 5–7 days. Unlike injection-molded coolers assembled from two halves, our rotomolded coolers are formed as a single seamless shell — no bond lines, no weld seams.
| Shell Material | LLDPE — food-safe, UV-stabilized |
| Insulation | Injected PU foam, 50–70 mm thickness |
| Wall Thickness | 18–25 mm total (shell + foam core) |
| Capacity Range | 20L · 35L · 50L · 75L · 100L · 150L (custom) |
| Ice Retention | 5–7 days at 30°C ambient |
| Colors | Custom color matching — RAL or Pantone |
| MOQ | 50 units (samples available) |
| Lead Time | Tooling 4–6 weeks · Production 3–4 weeks |
- Seamless single-piece shell — no joints to crack, leak, or fail under impact
- Thick, uniform walls for superior insulation vs. injection-molded alternatives
- Custom branding: embossed logos, custom colors, printed lids
- Bear-resistant certification achievable with appropriate latch hardware
Where the Ice Retention Comes From
Ice retention of 5–7 days at 30°C ambient is a result of how the box is built, not of a coating applied afterwards. The shell is rotomolded as one seamless piece of food-safe, UV-stabilized LLDPE, so there is no bond line between two halves for heat to travel through and no glued seam to fail under impact. The cavity between the walls is filled with injected polyurethane foam on our own line rather than fitted with a slide-in insert, which is why capacity can move across the 20L–150L range, or to a custom volume, without changing supplier. Color is matched to RAL or Pantone and logos are embossed into the mold, so branding weathers at the same rate as the shell.
