custom shipping boxes

Custom shipping boxes are corrugated cartons made to the internal dimensions, strength and print a business actually needs for despatch, rather than the nearest stock size. Custom Postal Boxes manufactures custom shipping boxes in Wolverhampton in single and double wall board, with low minimum order quantities, free design support and free UK delivery through a quote based order.

Choosing strength for custom shipping boxes

Corrugated board protects because its fluted middle layer cushions knocks and resists crushing when parcels are stacked. Single wall board suits most everyday products and keeps weight and cost down. Double wall board adds a second fluted layer and is the sensible choice for heavy, dense or fragile goods, long journeys and pallets stacked several boxes high. Choosing by weight, fragility and journey is more reliable than choosing by habit.

Our corrugated shipping boxes and heavy duty shipping boxes cover the stronger end of the range, while the wider custom shipping boxes collection shows the formats available. If you are unsure which wall grade your product needs, describe how it travels and what damage you see now, and the specification can be matched to that evidence.

Measuring for a made to measure carton

Box sizes are quoted as internal length by width by height in millimetres, measured with the product and any inner packaging in place. Allow a small working clearance so staff can pack quickly without forcing flaps, but avoid spare space that lets contents shift. For multi item orders, measure the most common combination rather than the single largest product, and consider a second size instead of one cavernous box for everything.

Why the shake test matters

Pack one box exactly as your team will pack it, close it and shake it gently. Movement means the fit or the padding needs attention before thousands of units are printed. A short test with your heaviest product, a drop onto a bench edge and a check of the corners will reveal more than any specification sheet about whether the box is right.

Print, closures and handling information

Printed shipping boxes carry more than a logo. Handling marks, orientation notes, a web address and reorder information all help the parcel and the customer after delivery. Keep essential handling information bold and placed where tape and labels will not cover it. Branding can be bold on the sides while the top stays practical for an address label and a clean tape line.

Most shipping cartons close with tape, and a centred tape seam with short cross strips is reliable for everyday weights. Heavier cartons benefit from a fuller taping pattern and, for very heavy goods, strapping. Where parcels travel by Royal Mail, check the packed size and weight against the Royal Mail prices page so the carton you love does not quietly move every order into a higher band.

Storing and using flat packed cartons

Shipping boxes are supplied flat, so they store compactly and are folded as needed at the bench. Keep stacks dry and off the floor, rotate stock so older cartons are used first and keep each size clearly labelled to prevent packing mistakes at busy times. Our custom shipping boxes are made to your sizes, so a simple bench chart matching products to box sizes keeps new staff packing consistently.

Getting custom shipping boxes quoted

Send internal dimensions or product measurements, product weight, how the goods travel and the quantity you expect to use. Pricing depends on size, material and quantity, so the quote reflects your specification rather than a shelf price. Free design support helps place print and handling information well, low minimum order quantities suit smaller runs and trials, and delivery is free across the UK. Enquire through the contact page for a quote to start.

Custom shipping boxes FAQs

Practical answers on strength, sizing and print for despatch cartons.

Should I choose single wall or double wall shipping boxes?

Choose single wall for light and medium weight goods on normal journeys, and double wall for heavy, dense or fragile products, tall stacks or longer journeys. Match the board to the weight and the damage risk rather than using one grade for everything.

How are custom shipping boxes measured?

They are measured by internal length, width and height in millimetres, with the product and its inner packaging in place. Add a small working clearance for packing, and test a sample packed exactly as your team will pack real orders.

Can shipping boxes carry handling information as well as branding?

Yes. Print can include logos, web addresses, handling marks and orientation notes. Place essential information where tape seams and courier labels will not cover it, and keep the wording bold enough to read at arm length in a busy warehouse.

Can I order a small first run of custom shipping boxes?

Yes. Low minimum order quantities make it practical to trial a new size or board grade before moving your full despatch volume onto it. Pricing depends on size, material and quantity, and each order is quoted individually.
