Whether you’re launching an online shop, packing and storing products for your business, or moving house, choosing the right boxes can feel surprisingly complicated. They may all look similar, but differences in strength, size, and cost can have a big impact.

If you’re reading this article, you’re probably considering buying used boxes and naturally have a few extra questions.

Are they strong enough? Will they really save me money? Can I get a consistent supply? And are they just as good as new boxes?

Asking these questions is good because doing so will help you cut costs, reduce waste, and keep your products safe.

Let’s look at some of the most common questions:

1. Will a used box be strong enough?

Yes. A used cardboard box can be strong enough, as its strength doesn’t necessarily decrease with use. What really matters is the corrugation, the wavy layer in the middle that gives structure. The tighter and closer the fluting, the stronger the box.

That’s why some single wall packing boxes can actually outperform certain double wall ones. A heavy-duty single wall box, for example, could hold up to 30kg, while lighter grades are better for smaller items.

When in doubt, consider your product’s weight, fragility, and how it will be shipped.

2. Could a different size work just as well?

Used boxes don’t always come in the exact sizes you’re used to, but that can work to your advantage. A slightly smaller box could cut down on void fill, while a slightly larger one may mean packing more products into a single box while still passing courier requirements. More important is to think about the size of your product, not the box itself.

Being flexible about dimensions means you’ll have more choices and often better value. For guidance on shipping limits, check out our resources, like our Royal Mail parcel size guide.

3. Does branding really matter to your customer?

It’s easy to assume branded packaging is essential, but for most customers, the priority is safe delivery, not the box design. A used box will do the job just as well as a new one, and if sustainability matters to your customers, they’ll appreciate the positive impact behind your choice of buying used boxes.

If branding is still important, simple touches like branded tape, stickers, or labels can give a professional finish at a fraction of the cost of custom-printed boxes.

4. What are lead times like for used boxes?

Unlike new boxes that typically have to be made to order, used boxes have zero lead times because they’re already made. We’ve spent many years building up supply chains so we can provide a consistent supply of used boxes in various sizes.

However, there is always the chance that certain boxes are available in limited quantities, especially surplus lines. It’s worth considering multiple size options so operations keep running smoothly without disruption.

5. Why choose used over new?

Once you’ve answered these key questions about strength, size, branding, and supply, the choice between used and new becomes clearer.

Used boxes can cost up to 50% less than new, and the environmental benefits are significant. According to our Environmental Calculator Tool, if every cardboard box worldwide were reused just once instead of recycled each year, we could save:

• 252 million trees
• 79.2 million tonnes of carbon
• 1.2 trillion kWh of energy
• 14.54 trillion litres of water

Reusing cardboard boxes is not only one of the simplest ways to cut costs, but it also helps protect the planet at the same time.

So now you know why reusing and buying used boxes makes sense. And why we’re encouraging more and more business to choose to reuse.
