Can I customise plain boxes with my logo or design?

Yes! While they come unbranded, our plain boxes are fully customisable with print and labelling options to suit your brand.

What sizes are available?

We stock a wide range of sizes to suit everything from small parcels to bulkier items. We can also manufacture custom sizes on request.

What is the minimum order quantity?

We offer low minimums on standard sizes—perfect for smaller businesses or trial runs. Custom orders may vary depending on size and finish.

What’s the difference between plain boxes and custom boxes?

Plain boxes come unbranded with a clean kraft finish—great for quick, affordable packaging. Custom boxes include printed designs, branded finishes, or specific structural features tailored to your product or brand.

Are your boxes food-safe?

While plain kraft boxes aren’t treated for direct food contact, they’re great for dry, pre-packaged, or secondary food packaging. If you need direct-contact food-safe packaging, just let us know.
