# Single wall box 400x400x250 mm

## **Single wall box 400 x 400 x 250 mm - forty litres in 3 mm board**

Forty litres of space on a square footprint, made in the thinnest single wall quality we keep in stock. That sounds like a contradiction and it is not, because thick board is wasted weight when the contents are light. The size is **400 x 400 x 250 mm** in 3 mm B-flute. Since 2007, we have been the go-to wholesaler for single wall folding cartons, and we supply this range from our [folding boxes](en/cardboard-boxes/folding-boxes) to firms that ship a lot of volume and little weight.

Anyone who needs to fit heavier goods onto this footprint is better off with the 4 mm C-flute or with [double wall shipping boxes](en/cardboard-boxes/folding-boxes/cardboard-boxes-double-wave). Those have a thicker wall and take more stacking pressure. For light items 3 mm B-flute remains the smarter choice, because you are not shipping board weight you do not need.

### **Commonly packed in this size**

**Textiles and clothing:** many pieces per consignment at a low weight.
**Empty packaging:** tubs, trays and bottles that only ask for volume.
**Promotional material:** displays, banners and folded print work.

### **Frequently asked questions**

### Why is this height in 3 mm while the shallower one is in 4 mm?

Because they are meant for different work. The taller 3 mm box takes bulky lightweight goods, the shallower 4 mm version heavier or more delicate items. The footprint and the pallet pattern match on both.

### Does a forty-litre box hold its shape?

It does if you fill it properly. Void space is the most common cause of bulging walls on thin board. Pack out with paper or film until the contents can no longer move around inside.

### What is the best way to close this box?

One strip of [tape](en/tape) along the centre seam is enough for light contents. If the box is filled to the brim, tape the short seams as well so the flaps cannot pull open.
