FDA Certified Bear Resistant Food-Grade LLDPE High-Density PU Foam

In a 25°C indoor environment, a cooler filled with ice will have the ice completely melt within 5–6 days. The one-piece rotomolded construction with high-density PU foam insulation ensures excellent thermal retention.

Learn more about our process: Process Overview

We use high-quality polyethylene (PE) resins, primarily LLDPE and HDPE, which are food-grade, UV-stabilized, and impact-resistant. We can also source specialty materials such as cross-linked polyethylene (XLPE) or custom formulations based on customer requirements.

Yes. All our products are formulated with UV stabilizers to resist degradation from prolonged sun exposure. They are designed for outdoor use in demanding environments such as marine, fishing, camping, and industrial applications. Our materials also resist cracking, fading, and weathering over time.

We manufacture coolers ranging from 10QT to 150QT and beyond. Custom sizes are available upon request — we can design and build molds for virtually any dimension. Our standard catalog includes 25QT, 45QT, 65QT, 85QT, and 120QT models.

The plastic wall thickness of the inner and outer shells typically ranges from 3mm to 8mm, depending on the product design and application. We can adjust wall thickness distribution to optimize strength, weight, and material usage.

The total cooler wall thickness, which includes the PU foam insulation layer between the inner and outer shells, is approximately 4.5–5.5 cm (1.8–2.2 inches). This foam-injected construction delivers superior thermal insulation and structural rigidity.

With proper care, a rotomolded cooler can last 10–20 years or more. The one-piece construction eliminates weak points like seams and joints, and UV-stabilized materials resist cracking and fading over time. Our products are built for long-term durability in harsh conditions.

Yes. We can design and manufacture custom inserts, dividers, trays, and accessories to organize and protect contents inside coolers. These can be customized to fit specific product dimensions and storage needs.

Our standard color options are available in our Color List.

Color customization: provide the Pantone code — MOQ 50 pieces per color (negotiable).

Yes, we can match any color using Pantone, RAL, or custom color swatches. Custom color MOQ is 50 pieces per color. Just provide the code and we'll produce a sample for your approval.

We offer multiple branding options:

Rotomolding and blow molding differ significantly in process, structure, and performance. For a detailed technical comparison, refer to our Rotomolding vs. Blow Molding.

Rotomolding produces hollow, seamless, one-piece parts with uniform wall thickness, ideal for large containers and coolers. Injection molding is faster but limited to smaller, more complex parts with varying wall thickness. Rotomolding is more cost-effective for low-to-medium volumes and larger products.

• Embossed logos: mold fee applies, no fixed MOQ

Due to the nature of the rotomolding process (each mold produces up to 20 units per day on a 24-hour shift), larger order quantities don't significantly reduce per-unit costs — we would need to add additional molds to increase capacity.

25–30 days after deposit confirmation and sample approval.

Monthly production capacity: approximately 20,000–30,000 coolers per month.

To be straightforward, per-unit costs do not decrease significantly with larger order quantities. This is due to the physical constraints of the rotomolding process: each mold produces only about 20 units per day (on a 24-hour shift). Producing 5,000 units requires 5 times the machine runtime of producing 1,000 units. Fixed production costs per unit — such as natural gas, labor, and equipment depreciation — remain essentially the same and do not decrease as volume increases.

For large orders, we can optimize in the following areas:

1. Parallel Mold Strategy: For stable, long-term orders, we recommend adding more molds (e.g., distributing production across 3 molds simultaneously). While this increases upfront mold costs, it significantly shortens delivery lead time.
2. Raw Material Sourcing: For high-volume orders, we can lock in bulk polyethylene (PE) pricing with our suppliers, achieving modest savings at the raw material level — though the savings are limited.
3. International Logistics: Full container load (FCL) sea freight has a much lower per-unit shipping cost than sample or LCL shipments, which can significantly reduce your total landed cost.

Bottom line: Fixed production costs per unit (natural gas, labor, etc.) do not decrease with larger order volumes. However, we can shorten lead times and reduce shipping costs through optimized mold allocation and logistics planning. We recommend sharing your estimated annual volume so we can tailor the most competitive proposal for you.
