Eco Coolbox 400 x 300 x 300 mm

Eco Coolbox — 400 × 300 × 300 mm, 18.2 liters, 100% recyclable cardboard. A ready-to-use insulation box made of compressed cardboard with a thick insulating wall. Ready for immediate use, lightweight, and the sustainable alternative to the EPS box or Styrofoam box.

Ready to use: no loose sheets needed

Unlike the cardboard insulation box with loose TempGuard sheets, the Eco Coolbox is a complete, pre-formed box: the insulation is integrated into the compressed wall itself. Unpack, fill, close — no assembly or loose parts. With an empty weight of only 1.6 kg, you also keep shipping costs low.

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 18.2 liters, this is the versatile standard size for medium shipments: fresh fish, meat, dairy, meal boxes, chocolate, and pharmaceutical products. The thick 2.9 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. Place gel packs or cooling elements on top of the product — cold air sinks and cools evenly.
3. Seal the box well before shipping.
