Cardboard Boxes by Strength: Single Wall, Double Wall & Heavy Duty

Not all cardboard boxes are created equal. The strength of your box depends on its wall construction, and choosing the right type prevents costly damage in transit. Here is a quick guide to help you decide.

Single Wall Cardboard Boxes

Our single wall cardboard boxes feature one layer of fluted corrugated board between two flat liners. They are lightweight, cost-effective, and ideal for general-purpose packing and shipping items up to approximately 10–15kg. With 83 sizes available, single wall boxes are our most popular product for everyday packaging and storage needs.

Double Wall Cardboard Boxes

Double wall cardboard boxes use two layers of fluted board for significantly greater strength and crush resistance. They are the preferred choice for shipping heavier items (up to 25–30kg), fragile products, or goods that require stacking during storage. We stock 73 double wall sizes to suit a wide range of applications.

Heavy Duty Cardboard Boxes

For the most demanding applications, our extra heavy-duty cardboard boxes provide a robust alternative to triple wall construction. Built for items exceeding 30kg, these boxes are widely used in manufacturing, engineering, and export environments where maximum protection is essential.

Cardboard Boxes by Size: Small, Large & Custom

Getting the right box size reduces void fill, cuts shipping costs, and improves the unboxing experience for your customers. Our range covers everything from 102mm cubes to large pallet-sized containers.

Small Cardboard Boxes

Our small packing boxes start at just 102 x 102 x 102mm, making them perfect for compact items such as jewellery, small electronic components, cosmetics, and craft supplies. Available in both single wall and white finishes for a premium presentation.

Large Cardboard Boxes for Storage & Shipping

Our large cardboard boxes are built for bulkier items such as bedding, appliances, homeware, and commercial stock. Available in single wall and double wall construction, these large boxes for shipping are a staple for warehouses, fulfilment centres, and removals firms across the UK. For long-term storage needs, our large cardboard storage boxes offer the strength to stack safely without collapsing.

Long Cardboard Boxes

Need to pack posters, blinds, curtain rails, or sporting equipment? Our long cardboard boxes are designed specifically for items that are significantly longer than they are wide. Available in double wall construction for added protection during transit.

Custom Sized Cardboard Boxes

When standard sizes won't do, our custom cardboard boxes are manufactured to your exact specifications. Use our online box builder to enter your dimensions, select your preferred wall type and colour, and receive an instant quote. Custom-sized boxes help eliminate wasted space, reduce void fill costs, and present your brand more professionally. Whether you need bespoke cardboard boxes for a unique product line or custom printed boxes featuring your logo, we make ordering simple.

Shipping Boxes & Packaging for Ecommerce

Online retailers need packaging that protects products, presents well on the doorstep, and keeps postage costs under control. Our range of shipping boxes and ecommerce packaging is designed to do all three.

Postal Boxes for Royal Mail & Courier Services

Our postal boxes are fully compatible with Royal Mail PiP guidelines, helping you send items at the lowest possible postage rate. Choose from brown or white finishes, with self-seal strips for fast packing. Our large letter boxes meet Royal Mail's 25mm depth limit for the most cost-effective postal option.

For removals firms, we offer trade pricing on bulk orders of packing boxes for moving house.

Packing Boxes & Cardboard Storage Solutions

Beyond shipping and moving, cardboard packing boxes are essential for warehousing, archiving, and general storage. Our range includes purpose-built options for long-term and short-term use.

Flat Pack Cardboard Boxes

All our cardboard boxes arrive flat packed, making them easy to store in your warehouse, stockroom, or spare room until needed. Flat pack boxes take up a fraction of the space of assembled cartons and can be erected quickly by hand with no tools required.

Cardboard Storage Boxes with Lids

Our archive and storage boxes feature integrated or separate lids for easy access and secure closure. Ideal for document archiving, seasonal stock rotation, and general warehouse organisation. Available in standard and premium grades with optional labelling areas.

Eco-Friendly & Sustainable Cardboard Packaging

Sustainability is at the heart of our operations. Every Kite cardboard box contains 60–90% recycled content and is fully kerbside recyclable. We are a certified Carbon Neutral company and partner with WRAP (the Waste and Resources Action Programme) to continuously improve the environmental impact of our packaging.

Our Enviro boxes deserve special mention: they use a reinforced single wall construction that matches the strength of traditional double wall boxes while using less raw material and producing 30% less CO₂ during manufacture. Choosing Enviro boxes means your business reduces its environmental footprint without compromising on protection.

Delivered Flat Packed for Easy Storage

When your order arrives, every box is flat packed to minimise storage space and reduce delivery emissions. Assembly is straightforward, simply fold and tape. With free standard delivery on orders over £45 and next-day options available, you'll have the packaging you need without delay.

Frequently Asked Questions About Cardboard Boxes

Are Cardboard Boxes Recyclable?

Yes. All Kite cardboard boxes are kerbside recyclable and contain 60–90% recycled content. Simply flatten your used boxes and place them in your household or commercial recycling collection. Cardboard is one of the most widely recycled materials in the UK, with recycling rates consistently above 80%.

Are Cardboard Boxes Sustainable?

Cardboard is one of the most sustainable packaging materials available. Unlike many plastics, cardboard can be recycled multiple times without significant loss of quality. At Kite, we go further by sourcing sustainably managed materials, partnering with WRAP, and operating as a Carbon Neutral business.

What Is the Difference Between a Cardboard Box and a Corrugated Box?

A standard cardboard box is made from a single layer of thick paperboard — think cereal boxes or gift boxes. A corrugated cardboard box has a fluted (wavy) layer sandwiched between flat liners, which provides significantly greater strength, cushioning, and protection. Almost all shipping and packing boxes are corrugated.

What Are Corrugated Boxes Used For?

Corrugated boxes are used across virtually every industry for shipping and transit, ecommerce fulfilment, warehouse storage and organisation, moving house or office, protecting fragile and heavy items, and retail display packaging. The fluted layer provides excellent shock absorption while keeping the overall package lightweight, making corrugated boxes the most cost-effective packaging choice for most businesses.

Where Can I Buy Cardboard Boxes Near Me?

You can buy cardboard boxes online from Kite Packaging with fast delivery to any UK address. We dispatch from multiple distribution centres across the country, with next-day delivery available on most orders placed before the cut-off time. There is no need to search for a local supplier when we can deliver directly to your door.

What Size Cardboard Box Do I Need?

The right box size depends on your product dimensions plus an allowance for protective packaging. As a general rule, choose a box that leaves 25–50mm of space on each side for cushioning material. Our size finder tool helps you match your product to the ideal box, or you can contact our team for personalised advice.

Can I Order Custom Printed Cardboard Boxes?

Yes. Kite offers custom printed and branded boxes in a range of sizes and print options. Add your logo, brand colours, handling instructions, or sustainability messaging directly to your packaging. Custom printing is available on both standard and bespoke box sizes — contact our team for a quote.
