What is a single wall cardboard box?

A single wall cardboard box is a box made with one layer of corrugated cardboard. Single walled boxes are often used in e-commerce shipping as they are lighter and cheaper than double walled boxes but still offer a strong and robust method of packaging goods for transport.

Single wall cardboard boxes are a cost-effective way of shipping goods for both personal and professional uses.

Our brown single wall boxes are supplied flat packed in packs of 25 with a wide variety of internal dimensions available. Once you’ve received your order from us, the single wall cardboard boxes can be made ready for use using packaging tape.

The high quality single wall corrugated cardboard we use guarantees a strong and reliable single wall carton that is perfect for packaging products, long term storage projects, and use as removal boxes.

Our single wall cardboard box range

Long single wall cardboard boxes are great for keeping postage costs down by suiting the Royal Mail’s category dimensions. Long single wall boxes are a good choice for lighter goods.

Short single wall cardboard boxes will keep your packages as light as possible. Use our square single wall cardboard boxes for storing and stacking boxes together and shipping regular shaped products.

Tall single wall cardboard boxes are for when you need to keep a package upright with a height greater than the length and the width. Perfect for those products that might not fit into any other kind of box.

So, whether you’re moving to a new office or shipping products to your customers, our single wall cardboard boxes with a puncture resistant kraft outer layer give you an economical and safe way to package your goods.
