big postage boxes

big postage boxes are large postal cartons used across a range of bulky orders, giving a business a set of bigger sizes that cover appliances, homeware, toy sets and multi item deliveries without forcing each order into an unsuitable small box. Custom Postal Boxes makes big postage boxes to order in Wolverhampton for UK sellers, with sizes and board grades matched to the orders each business actually sends. Free UK delivery, free design support and low minimum order quantities keep a larger range practical.

A range works when each size has a clear job. Too few sizes waste board and postage, while too many sizes slow packing and storage.

Building a useful range of big postage boxes

Start by reviewing recent large orders and grouping them by packed size and weight. Most sellers find that two or three large sizes cover the great majority of bulky orders, with one deeper box for cube shaped goods and one longer box for flatter wide items. Our cardboard shipping boxes give a starting point for everyday large orders, and our corrugated shipping boxes suit loads that need more crush resistance. Keep the range under review as products change, because a new best seller can shift the size you reach for most.

How large boxes map to postage bands

Large orders most often fall into the Royal Mail medium parcel band, up to 610 mm by 460 mm by 460 mm and up to 20 kg for relevant services, while anything that fits 450 mm by 350 mm by 160 mm and 2 kg can still travel as a small parcel. Check the Royal Mail prices and size guidance when you plan the range, and remember that couriers set their own size and weight rules. Designing each box with a target band in mind prevents a carton that is needlessly just over a limit.

Storing and handling large cartons

Large boxes are supplied flat, so store them in size order with clear labels at the packing bench and keep the most used size closest to hand. Flat storage protects edges and corners, which are the parts that give a folded box its strength. Train packers to fold along the creases, support the base while filling and avoid dragging filled boxes across rough floors, which can weaken the bottom panels before dispatch.

Board choices across the range

Not every large box needs the strongest board. Single wall cartons suit light bulky goods across many orders, while double wall cartons should be reserved for heavy, fragile or stacked loads so cost stays sensible. Our single wall corrugated boxes show the lighter option in this family. Using the right grade for each size also cuts waste, and businesses can read the packaging producer responsibility guidance on GOV.UK for the wider duties linked to placing packaging on the market.

Print and labelling across sizes

Consistent print across a range makes every large parcel recognisably yours and can carry handling guidance in the same place on each size. Keep the logo, a fragile note where needed and returns wording clear of tape lines and label areas. A simple size code printed inside a flap helps packers pick the right carton quickly and helps you reorder the correct size without measuring stock.

Ordering big postage boxes for your range

Bring your order history, the largest and heaviest items you send and the sizes you currently struggle with. The custom shipping boxes category shows the wider family these cartons sit within. Pricing depends on size, material and quantity, so request a quote through our contact page for the full range rather than one size at a time, which helps the specification stay consistent.

FAQs about big postage boxes

How many sizes of big postage boxes do I need?

Most businesses need two or three sizes of big postage boxes to cover their bulky orders well. Group recent orders by packed size and weight, choose sizes that cover the common groups closely and keep one option for the largest items you send only now and then.

Are big postage boxes supplied flat?

Yes. big postage boxes are supplied flat and folded into shape at the packing bench, which saves storage space and protects the board before use. Store each size in a labelled stack, fold along the creases and tape the base fully before filling the box.

What board is best for big postage boxes?

The best board for big postage boxes depends on the load in each size. Single wall board suits light bulky goods, while double wall board suits heavy, fragile or stacked orders. Matching grade to load keeps protection high without using strong board where it is not needed.

Can big postage boxes carry my branding?

Yes. big postage boxes can be printed with your logo, artwork, handling guidance and returns wording in a consistent layout across every size in the range. Consistent print makes large parcels recognisable, helps handlers treat them correctly and speeds reordering of each size.
