custom large shipping boxes

custom large shipping boxes are made for orders that will not fit a standard parcel box, from bulky single items to several products packed together for one delivery. They use strong corrugated board, generous internal space and a structure that resists crushing, stacking pressure and rough handling. When the size, board grade and closure are matched to the contents, large orders arrive intact and look professional on arrival.

Why choose custom large shipping boxes for bulky orders

A large box that is too weak will bow at the sides, crush at the corners or split along a seam when it is stacked or lifted. A box that is far too large will let contents move, waste void fill and increase the chance of damage in transit. The right custom large shipping boxes solve both problems by giving the product room to be protected without room to slide around. That balance matters most for furniture parts, bedding, sports equipment, bulk clothing orders, multi item gift sets and business to business deliveries where one parcel carries a full order.

Strength starts with board choice. Single wall board suits lighter bulky items such as cushions, folded textiles and empty presentation cases. Double wall board suits heavier goods, stacked pallets and items that will travel through several handling stages. Triple wall board can be considered for very heavy or awkward loads, although it adds weight and bulk, so it should be chosen only when the load genuinely needs it. Your quote request should state the packed weight, the longest side and whether parcels will be stacked, so the board can be matched to the job rather than guessed.

How size affects protection and handling

Measure the product first, then add space for protection. Length, width and height should be internal measurements, taken with any lid, handle or protruding part included. Allow room for edge protectors, dividers or cushioning where the product has corners that can dent or surfaces that can scratch. A snug fit with thoughtful protection usually protects better than a very large box filled with loose material, because the product stays in place when the parcel is tilted or dropped.

Checking a large box before a full run

Before ordering in volume, pack a sample exactly as you would pack a customer order, seal it, lift it by the base and turn it gently in each direction. Listen for movement, check for bulging sides and look at the corners after the test. If the product moves, add a divider, a fitted insert or a different cushioning layout rather than simply choosing a larger box. This simple test often prevents returns, replacements and damage claims.

Materials and construction for custom large shipping boxes

Corrugated board is the usual choice for large shipping boxes because the fluted layer between two flat liners gives strength without excessive weight. Kraft liners give a natural brown finish that suits many brands and prints well with simple artwork. White liners give a cleaner surface for full colour print and for labels that must stay easy to read. The finish, the flute profile and the board grade should be agreed at quote stage, because each choice affects print quality, stacking strength and how the box behaves in damp storage.

Closure matters as much as board. Wide packing tape applied along the centre seam and across the ends gives a reliable seal for most large parcels. For heavier loads, reinforced tape or strapping may be needed, and the box design should allow tape or strapping to sit flat without cutting into the board. Hand holes can help with lifting, but they weaken the side panels, so they should be used only when the contents and the board grade allow it. If a box will be opened and resealed, for example for a return, a tear strip or a resealable flap can be a useful addition.

Print and labelling on a large surface

A large outer surface gives room for clear branding, handling instructions and product information, but the layout still needs care. Place the main logo where it will be seen when the parcel is stacked or carried, and keep the delivery label area free of heavy print so barcodes and addresses stay readable. Handling marks such as this way up, fragile or keep dry should be large enough to read at a glance and placed on more than one face if the parcel may be turned. Simple, bold artwork often prints more reliably on corrugated board than very fine detail.

Keeping print readable after transit

Test print on the actual board colour you plan to use, because the same artwork can look very different on brown kraft and on white board. Dark inks on kraft can lose contrast, while pale colours on white board can look washed out. Ask for a proof before production and check it in normal daylight, not only on a screen. If the box will be stored outdoors or in a damp warehouse for a time, discuss a suitable finish that helps the print stay legible.

Ordering and delivery for custom large shipping boxes

Ordering large boxes starts with a clear specification: internal size, board grade, print artwork, quantity and how the boxes will be stored. Flat packed boxes save warehouse space and are easier to move, but very large flat packs still need racking or pallet space, so check the pack size before you confirm storage. If you pack on a bench, make sure the assembled box fits the bench and can be lifted safely when full. For regular large orders, keeping one standard large size in stock and using inserts for smaller products can simplify packing and reduce waste.

After final artwork approval, standard lead times are 10 to 14 working days and corrugated lead times are 12 to 15 working days. These are production guides, not guaranteed delivery dates, and they can vary with quantity, print complexity and board availability. You can read the full delivery guidance through the delivery information page. Plan seasonal peaks early, because large boxes take more storage and transport capacity than small parcels. You can also request a quote for large shipping boxes with your sizes and quantities, and browse the full shop for related packaging. For a related strength option, see custom made cardboard shipping boxes. When posting through Royal Mail, check the current size and weight limits on the Royal Mail Tracked 24 service information page, because a large parcel may need a courier service instead.

Packing large orders well

Pack heavy items at the base and lighter items above them, and keep weight balanced from side to side so the parcel does not tip when lifted. Use dividers to stop items rubbing together, and protect corners and edges first, because those are the points most likely to show damage. Fill remaining space with cushioning that holds its shape, rather than loose material that settles to the base during transit. Seal the box fully, label it clearly and, for very heavy parcels, mark the weight on the outside so handlers can lift it safely.

Storage and reuse in the warehouse

Store flat packed large boxes flat, dry and away from direct heat, and keep them off concrete floors where damp can soften the board. Rotate stock so older boxes are used first, and keep a small number assembled for urgent orders. If customers may reuse the box, choose a closure that opens cleanly and print reuse or recycling guidance inside the lid where it will be seen on opening. Cardboard boxes can usually be recycled through household or business cardboard recycling, provided tape and labels are removed where local guidance asks for that.

Frequently asked questions

What size counts as a large shipping box?

There is no single legal definition. In practice, a large shipping box is one that holds bulky items, several products or a heavy order that will not fit comfortably in a standard small parcel box. The useful measure is the internal size against your product and its protection, plus the packed weight and the carrier limits for the service you plan to use.

Should I choose single wall or double wall board?

Choose single wall board for lighter bulky goods and double wall board for heavier goods, stacked parcels and longer journeys. If you are unsure, state the packed weight and the journey in your quote request, and let the board grade be matched to that load.

Can large shipping boxes be printed with my logo?

Yes. Large boxes give a generous print area for a logo, brand colours and handling information. Keep the delivery label area clear and check a proof on the actual board colour before production.

How do I avoid damage in a large box?

Measure the product, allow room for protection, stop movement with dividers or inserts, protect corners first and seal the box fully. Pack a test parcel before a full run and adjust the internal layout if anything moves.

Are large boxes suitable for Royal Mail delivery?

Some large boxes fit Royal Mail parcel limits and some do not. Check the current Royal Mail size and weight limits before you choose a service, and use a courier for parcels that exceed those limits.
