insulated box (L) 355 x 355 x 355 mm — complete incl. 2 Isoliners

Insulated box (L) — complete cardboard cold shipping box per unit: corrugated cardboard outer box 355 × 355 × 355 mm including 2 Isoliners. Everything you need for one fully fledged, fully recyclable cold chain packaging solution to ship your products chilled — the plastic-free alternative to EPS and polystyrene foam.

What’s included?

Per unit, you receive the corrugated cardboard outer box and the 2 matching Isoliners — paper insulation sheets that line the entire inside: base, walls and top. Set up the box, insert the sheets, pack your goods: done. Do you ship regularly? Order the Isoliners separately at an attractive price as a refill: Isoliner sheets (L) — 36 sheets for 18 boxes.

Why choose a cardboard cold shipping box with separate sheets?

This system is designed for businesses that want to save storage space and package sustainably. The box is delivered flat and the sheets are stored flat — you only assemble the cold shipping box when packing. This saves significant storage space and transport volume compared with preformed EPS boxes. And after use, both the box and the sheets can simply go with the waste paper, with no separate collection point required. The insulation performance is comparable to EPS (polystyrene foam/Styrofoam).

How to assemble the cold shipping box

1. Set up the box and insert the two supplied Isoliners so that the base and walls are lined.
2. Place your product inside and add gel packs — gel packs 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 L size suitable for?

The L is the largest size, intended for bulky or heavy chilled shipments: larger meat and fish consignments, full meal boxes, multiple products at once or pharmaceutical shipments with a higher volume. With the right gel packs, the contents remain at the required temperature for up to 48 hours, from chilled (2–8 °C) to frozen — without a refrigerated vehicle.
