Eco Coolbox 400 x 300 x 300 mm white

White Eco Coolbox — 400 × 300 × 300 mm, 18.2 liters, 100% recyclable cardboard. A ready-to-use insulation box made from pressed cardboard with a fresh white exterior. Sustainable, plastic-free, and presentable — the premium alternative to the EPS or polystyrene box (Styrofoam).

The same performance, with a professional white appearance

The white Eco Coolbox is the same strong, ready-to-use insulation box as our standard Eco Coolbox 400 × 300 × 300 mm, but with a clean white finish. The insulation is integrated into the pressed wall itself, so the box is ready to use immediately — no loose sheets or assembly required. The white exterior looks professional and sleek: ideal for brands that want to combine sustainability with a strong presentation on the customer’s doorstep.

The box is made from recycled cardboard, 100% recyclable, and completely plastic-free, with insulating performance that is at least comparable to a Polystyrene Box. After use, the box can simply be disposed of with paper recycling.

What is this box suitable for?

With a capacity of 18.2 liters, the white Eco Coolbox is suitable for medium-sized shipments of fresh fish, meat, dairy, meal boxes, chocolate, and pharmaceutical products. The thick 2.9 cm wall keeps the contents at the right 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 vehicle. The white appearance makes this box particularly suitable for e-commerce and premium fresh food brands that see packaging as part of the brand experience.

How to achieve the best results

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

Why choose the white Eco Coolbox?

You get the sustainability and ease of use of the Eco Coolbox, plus a professional white presentation that strengthens your brand. Fully recyclable, plastic-free, and lightweight. If you do not need a white appearance, the standard Eco Coolbox is a more cost-effective choice. For longer or more demanding shipments, our thermal boxes offer higher insulation performance.
