FAQ – Approved insulated cardboard

1. What is the difference between a standard insulated box and an approved insulated box?

Our cardboard is UN certified for transporting hazardous materials, with insulation tested to ensure thermal stability throughout transport.

2. What temperatures can it withstand?

Our models maintain the cold chain between +2°C and +8°C for 24 to 72 hours, or below -20°C for frozen goods.

3. Can I use it for sea or air transport?

Yes, the boxes are approved for all types of transport: road, sea, rail, and air.

4. Do you provide the accessories?

Yes, each insulated box can be delivered with a plastic bag, absorber, PCM brick, or even a temperature logger upon request.

5. Can the box be reused?

The box loses its UN certification after first use. It is therefore recommended to replace it for each shipment.

E3 Cortex

Safety, Compliance, and Innovation in Regulated Thermal Transport

Certified insulated cardboard is essential for transporting temperature-sensitive regulated products, whether chemical, pharmaceutical, biological, or food items. At E3 Cortex, we have designed a solution that addresses thermal stability challenges while complying with the strict rules of Transport of Dangerous Goods (TDG).

Our cartons combine a reinforced triple-wall cardboard structure, thick insulating inserts, and optional PCM bricks to extend shelf life. All components are validated through compliance tests conducted by accredited laboratories.

The 4GV insulated cardboard is recognized for its ease of integration into existing supply chains. It is suitable for large industries in chemicals, healthcare, logistics, and food sectors, with full traceability for shipped batches.

E3 Cortex

Regulatory Thermal Packaging Designed for Field Constraints

Our UN-certified insulated cartons allow the transport of sensitive substances without breaking the cold chain. Whether for biological samples, medicines, or reagents, packaging compliance is a critical concern for our clients.

Each certified insulated carton is designed to provide an effective barrier against thermal shocks. Depending on the requirements, the models are equipped with vermiculite, PU foam, or EPS panels, and optionally an NFC logger to ensure temperature control.

Our solutions are tested according to ISTA 7D, S99-700, ADR standards and internally validated through drop, stacking, and humidity resistance tests. This ensures compliant use in road, air, or sea transport.

Facing today's climate challenges, E3 CORTEX aims to contribute to reducing its carbon footprint. This document, called the “Recyclability Sheet,” is intended to inform our partners about the environmental impact of our products. We continuously strive to find “clean” alternatives for all our products, despite regulatory constraints on transporting dangerous goods, which limit, to some extent, the use of recycled or bio-based components. The lifecycle of our products has been calculated using the IDEMAT database (environmental data dedicated to materials and industrial processes).
