Eco Coolbox 600 x 400 x 375 mm

Eco Coolbox — 600 × 400 × 375 mm, 49.8 liters, 100% recyclable cardboard. Our largest ready-to-use insulation box made of pressed cardboard, with an extra thick 4 cm wall. Ready to use immediately and the sustainable alternative to large EPS or styrofoam boxes.

Ready to use: no loose sheets needed

Unlike cardboard insulation boxes with loose TempGuard sheets, the Eco Coolbox is a complete, pre-formed box: the insulation is built into the pressed wall itself. Unpack, fill, close — no assembly or loose parts. This 600 × 400 × 375 mm version has an extra thick 4 cm wall and offers 49.8 liters of space for large or multiple shipments at once.

The box is made from recycled cardboard, 100% recyclable and completely plastic-free, with insulating performance that is at least comparable to an EPS box. After use, the box can simply be recycled with paper waste.

What is this size suitable for?

With nearly 50 liters of capacity and a load up to 25 kg, this is the choice for large or heavy shipments: larger portions of meat and fish, full meal boxes, dairy, or bulk shipments of temperature-sensitive products. The extra thick 4 cm wall keeps the contents at temperature for a long time; with the right gel packs, you can bridge 24 to 48 hours of transit, from chilled (2–8 °C) to frozen — without a refrigerated truck.

How to get the best results

1. Fill the box as tightly as possible; less empty space means a more stable temperature.
2. Distribute the gel packs and place them on top of the product — cold air sinks and cools evenly.
3. Seal the box well before shipping.
