Double wall cardboard boxes - 350 x 220 x 200mm

Cardboard boxes 350 x 220 x 200 mm – elongated double wall model

With a length of 350 mm this is a clearly elongated format, while width and height remain modest. That ratio is exactly what you need for products that are mainly long: a keyboard, a lamp, a stick appliance, profiles or a rolled-up poster with accessories alongside. Since 2007, we have been the go-to wholesaler for shipping boxes, which is why we also keep the less obvious proportions in stock.

In an elongated box, the weak point is the middle of the long side, where thin board can bend as soon as you lift the box by its ends. The 7 mm double wall keeps that long wall rigid, so the box holds its shape along its full length.

Suitable for

Long items: anything that just won't fit in a square box.
E-commerce: a compact volume despite the length, so a favourable parcel rate.
Sets with accessories: main product and accessories side by side in a single layer.

Frequently asked questions

Can I fill one end of the box more heavily?

Preferably not. In an elongated model, uneven weight distribution makes the box sag. Spread the weight and fill any empty space.

Which tape should I use for the long seam?

A dispenser with a 50 mm roll works best here: you seal the full length in one movement. Our tape range includes rolls to match.

Is there a shorter version with the same profile?

Yes, the 310 x 220 x 200 mm size has the same width and height but is 40 mm shorter. Useful if your product falls just within that length.
