Cold Chain Shipping Boxes
Engineered expanded polystyrene (EPS) cold chain shipping boxes for the reliable passive temperature-controlled distribution of food, pharmaceutical, and biological products across any supply chain.
Engineered for the job it protects.
Insutech's EPS Cold Chain Shipping Boxes are the backbone of passive temperature-controlled logistics, providing reliable insulation for the distribution of perishable food, pharmaceutical products, biological materials, and any cargo requiring controlled temperature throughout transit. Manufactured from high-quality expanded polystyrene, our shipping boxes maintain target temperatures — from frozen sub-zero to controlled ambient — across the full duration of the delivery mission.
Cold chain failure is costly: spoiled products, compliance breaches, and wasted refrigerants represent significant losses across food and pharma supply chains. Insutech's EPS cold chain boxes are engineered with consistent wall thickness, precision-fit lids, and density-optimised foam to deliver repeatable, predictable thermal performance that logistics operators can depend on.
- Reliable passive temperature control from −40°C to +25°C depending on refrigerant
- Consistent thermal performance with uniform wall thickness and tight dimensional tolerances
- Compatible with ice, gel packs, dry ice, and phase-change material refrigerants
- Precision snap-fit or friction-fit lids minimise temperature leakage at the lid interface
- Available in configurations for 2–8°C, 15–25°C, frozen, and deep-frozen products
- Lightweight reduces total shipment weight and freight costs versus rigid insulated containers
- Fully customizable internal dimensions to accommodate diverse product configurations
- Outer surfaces compatible with standard outer carton and strapping systems
Reliable Passive Temperature Control
EPS foam delivers consistent, passive insulation performance requiring no power, electronics, or active components — providing temperature-controlled protection in any location, regardless of power infrastructure availability.
Multi-Application Temperature Capability
Cold chain shipping boxes can be configured for 2–8°C refrigerated, 15–25°C controlled ambient, frozen (−18°C), and deep-frozen (−40°C) applications through adjustments to wall thickness, density, and refrigerant selection.
Precision Lid Seal
Snap-fit and friction-fit lids are precision-moulded to minimise the temperature leakage that typically occurs at lid-body interfaces — a critical performance differentiator for longer-duration transit missions.
Consistent, Repeatable Performance
Insutech EPS cold chain boxes are manufactured with tight dimensional tolerances and consistent foam density, ensuring batch-to-batch repeatability — essential for validated cold chain programmes in food and pharmaceutical industries.
Lightweight for All Freight Modes
EPS shipping boxes add minimal tare weight to shipments, reducing freight costs across road, air, and ocean cargo — making them particularly cost-effective for high-frequency, high-volume cold chain programmes.
Fully Customizable
Every dimension of the cold chain shipping box — from internal cavity size to wall thickness, lid design, and outer finish — can be customized to the specific product, route, ambient profile, and duration requirements.
