High Light 90L rotomolded food carrierLLDPE insulated thermal boxcommercial kitchen food transport

Product Introduction

The 100L Rotomolded Food Carrier represents the pinnacle of insulated food transport engineering. Manufactured through the rotational molding process, this carrier features a truly seamless, one-piece double-wall LLDPE construction with an integral PU foam insulation core—there are no joints, welds, or seams that could fail under stress or harbor bacteria. This construction method delivers exceptional structural integrity: the carrier withstands impacts that would dent metal boxes, resists cracking in freezing conditions, and maintains its insulation performance year after year. The 100-liter capacity accommodates large-volume food transport for central kitchens, food manufacturing facilities, and high-capacity catering operations. With 45-55mm of high-density PU foam insulation, it achieves industry-leading temperature retention of 5-7 hours for hot food and 7-9 hours for cold items.

Key Features

  • True Seamless Construction: Rotomolding produces a one-piece hollow shell with no seams, welds, or joints. This eliminates water ingress points, bacterial traps, and structural weak spots inherent in fabricated or injection-molded alternatives.
  • Uniform Wall Thickness: The rotational molding process ensures consistent wall thickness throughout the entire shell, providing uniform insulation performance and structural strength in every area of the carrier.
  • Maximum Insulation Performance: 45-55mm of closed-cell PU foam injected between inner and outer walls creates a superior thermal barrier that outperforms traditional panel-insulated carriers by 20-30%.
  • Impact and Chemical Resistant: LLDPE material resists impacts, chemicals, cleaning agents, and UV exposure. The carrier maintains its appearance and performance even after years of daily commercial use.
  • Integrated Structural Ribs: Molded-in reinforcement ribs at high-stress points (corners, base, lid) provide additional strength without adding weight or creating seams.
  • Commercial-Grade Hardware: Stainless steel hinges, latches, and fasteners resist corrosion in humid kitchen environments. All hardware is replaceable for extended service life.

Why Choose Us

  • Rotomolding Specialists Since Day One: Rotational molding is not just a process we use—it is our core expertise. With over 20 years focused exclusively on rotomolding, we bring deep technical knowledge to every product.
  • In-House Mold Design and Fabrication: We design, machine, and maintain all our molds in-house, enabling rapid prototyping, precise quality control, and efficient custom projects.
  • Material Science Expertise: We select and test LLDPE formulations specifically optimized for food transport applications—balancing impact strength, UV stability, food safety compliance, and processing characteristics.
  • End-to-End Quality Control: From raw material inspection through finished product testing (thermal performance, drop testing, load testing), every carrier is verified before shipment.

Frequently Asked Questions

Q: What makes rotomolding superior to injection molding for food carriers?

Rotomolding produces seamless, stress-free parts with uniform wall thickness—eliminating the weld lines and weak points common in injection-molded products. The process also enables true double-wall construction with integral foam insulation in a single manufacturing step, resulting in superior thermal performance and structural integrity.

Q: How long will a rotomolded carrier last in commercial use?

With proper care, our rotomolded carriers typically provide 8-12+ years of daily commercial service. Unlike metal carriers, they do not rust, dent, or corrode. Unlike injection-molded carriers, they resist cracking from impacts and temperature cycling. Replaceable hardware further extends service life.

Q: Can the carrier be repaired if damaged?

LLDPE can be repaired using plastic welding techniques for cosmetic surface damage. However, the seamless construction means that structural damage is extremely rare. In the unlikely event of severe damage, the modular hardware (casters, latches, hinges) can be individually replaced.
