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 of pressed cardboard with a fresh white exterior. Sustainable, plastic-free, and presentable — the premium alternative to the EPS box or styrofoam box.

Same performance, 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 built 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 impression on the customer’s doorstep.

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

What is this box suitable for?

With 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 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. The white appearance makes this box especially suitable for e-commerce and premium fresh brands that see their packaging as part of the brand experience.

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.

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 don’t need a white appearance, the standard Eco Coolbox is a more cost-effective choice. For long-term or extra demanding shipments, our thermal boxes offer more insulation performance.
