Insulation box (M) 300 x 300 x 300 mm - 100% recyclable cardboard

Insulation box (M) — 300 × 300 × 300 mm, 100% recyclable corrugated cardboard. The medium-sized outer box of the TempGuard cooling system. Combine it with separate TempGuard insulation sheets (M) to create a fully functional, completely recyclable cooling box — a plastic-free alternative to EPS and styrofoam.

Note: this is the box, not the insulation

The Insulation box (M) is the corrugated cardboard outer box. The insulating effect comes from the TempGuard insulation sheets (M), which you order separately and place inside the box. Together they form a cooling box; used separately, the box functions as a regular shipping box. If you prefer a box that insulates immediately without separate sheets, check out the Eco Coolbox or the honeycomb insulation box.

Why a cardboard insulation box with separate sheets?

This system is designed for companies that want to store compactly and package sustainably. The box is delivered flat and the sheets are stocked flat — you add the insulation only when packing. This saves significant storage space and transport volume compared to pre-formed EPS boxes. After use, both the box and sheets can simply be recycled with paper waste, without a separate collection point. The insulation value of the combination is comparable to EPS (styrofoam/tempex).

How to assemble a complete cooling box

1. Set up the box and place two TempGuard insulation sheets (M) so that the bottom and walls are lined.
2. Place your product inside and add gel packs — gel packs go on top of the product because cold air sinks.
3. Fold the sheets closed and seal the box. Pack as tightly as possible: less empty space means a more stable temperature.

What is the M size suitable for?

The M is the versatile middle size for most cooled shipments: medium-sized packages of fresh fish or meat, dairy, meal boxes, chocolate, and pharmaceutical products. With the right gel packs, the contents stay at temperature for up to 48 hours, from chilled (2–8 °C) to frozen — without a refrigerated truck.
