Cardboard Boxes

With over 70 years of industry experience, we know cardboard boxes inside and out; making us the ideal packaging partner for your business. Whether you need simple paperboard or heavy-duty triple-wall corrugated solutions, we have the expertise to match your packaging needs with the perfect box. At RAJAPACK, we offer a vast selection of standard and specialist boxes and packaging materials to ensure you get the best options available.

RAJAPACK stocks over 900 cardboard box sizes from single wall transit cartons through to triple wall export grade, supplying businesses of every size from sole traders and small e-commerce sellers through to multi-site enterprise accounts. Most orders ship next working day on the standard service from UK stock. Where pack sizes do not match what you actually need, RAJAPACK manufactures bespoke and printed boxes against your internal dimensions, typically on a 2 to 4 week lead time depending on volume and print specification. 

If you are choosing between single, double, reinforced double and triple wall, the honest rule is to size by weight first and fragility second. Single wall handles general dispatch up to 30 kg. Double wall covers fragile or heavier goods up to 40 kg. Reinforced double wall steps up to 70 kg for export-grade transit. Triple wall takes the heavy lifting up to 500 kg for highly fragile items, machinery and international shipping. If the goods are light and the journey is short, single wall is cheaper, lighter and still 100 percent recyclable.

Choosing the Best Packaging Boxes

Finding the right cardboard boxes for your products can feel overwhelming. Every business has unique packaging requirements. A company shipping delicate e-commerce orders needs a different solution from one transporting industrial machinery. Identifying your needs is the first step to making the best choice. By understanding what each type of box is designed for, you can be sure you're picking the right packaging to protect and deliver your goods.

Single Wall Cardboard Boxes

Lightweight yet reliable, our single wall cardboard boxes are perfect for general packaging and storage. Made from high-quality corrugated cardboard, they offer a cost-effective solution for businesses handling lightweight shipments or looking to buy in bulk. These boxes are a staple for efficient packaging.

Double Wall Cardboard Boxes

For added durability and protection, double wall cardboard boxes feature an extra corrugated layer, making them ideal for shipping heavier or more delicate goods. Their reinforced structure absorbs impacts and resists crushing, ensuring your items stay safe in transit. Perfect for stacking, storing, and shipping with confidence.

Triple Wall Cardboard Boxes

When maximum protection is a must, triple wall cardboard boxes are the ones for you. They offer the highest level of strength and durability available. Designed for transporting heavy, fragile, or high-value items over long distances, these boxes withstand impacts, temperature changes, and rough handling. If you need the ultimate safeguard for your shipments, triple wall is the way to go.

Cardboard Postal Boxes

Speed and convenience are essential for e-commerce and retail shipping. Our cardboard postal boxes are quick to assemble, secure, and designed for effortless packing. Whether you’re sending out small parcels or branded subscription boxes, these packaging solutions streamline the shipping process for a smooth customer experience.

Archive and Removal Boxes

Need to store important documents or move office supplies? Our archive and removal boxes provide practical storage and transport solutions. Available in multiple sizes, these sturdy boxes keep files, records, and belongings organized and protected, whether for temporary storage or a full office relocation.

Cardboard Boxes Frequently Asked Questions

What is the difference between single wall, double wall and triple wall cardboard boxes?

Single wall cardboard boxes have one fluted layer between two sheets of liner and support loads up to 30 kg, suitable for light to medium dispatch and short-distance shipping. Double wall has two fluted layers and three liners, supporting up to 40 kg for fragile or heavier goods. Reinforced double wall is stronger again, supporting up to 70 kg and recommended for export and demanding shipping conditions. Triple wall has three fluted layers and four liners, supporting up to 500 kg for highly fragile items, machinery, international shipping and long-term storage.

How do I work out what size cardboard box I need?

Measure the internal length, width and height of the item you are shipping in millimetres. Add 10 to 30mm of clearance on each dimension for protective packaging like bubble wrap or paper void fill. Use the RAJAPACK Box Selector to enter those dimensions and find matching boxes from our 900 plus range. If your item is fragile, size up rather than down.

Are RAJAPACK cardboard boxes recyclable and made from recycled material?

Yes. Every cardboard box in the RAJAPACK range is 100% recyclable through kerbside collection in the UK once tape and labels are removed. Our cardboard boxes are made with at least 70% recycled content as standard. RAJAPACK is independently rated by EcoVadis in the top 5 percent of suppliers globally for sustainability.

Can small businesses buy cardboard boxes from RAJAPACK?

Yes. RAJAPACK supplies businesses of every size, from sole traders and small e-commerce sellers through to multi-site enterprise accounts. There is no minimum business size requirement. Cardboard boxes are sold by the pack in pack sizes that suit lower-volume buyers as well as bulk and contract customers.

Do you offer bulk discounts and trade pricing on cardboard boxes?

Yes. RAJAPACK offers contract pricing and tiered bulk discounts on all cardboard boxes. Pricing improves at pack, pallet and contract volumes. Contact our packaging experts for a tailored quote or open a business account online.

What is the minimum order quantity for cardboard boxes at RAJAPACK?

Most cardboard boxes are sold by the pack. Pack sizes vary by product, typically 10, 15, 20 or 25 units. For bespoke and printed runs, minimum order quantities depend on box size, print specification and board grade. Contact the RAJAPACK team for a tailored quote.

What is the difference between a cardboard box and a corrugated box?

Every transit and shipping box sold by RAJAPACK is corrugated cardboard for strength, even when listed simply as a cardboard box.

How quickly can I get cardboard boxes delivered in the UK?
