Postal Packaging

Custom mailing boxes

Cost-effective postal packaging boxes offer significant benefits if your business sends out eCommerce orders, mail-order goods, or even supplies to retail outlets.

Postal packaging protects goods throughout the various touchpoints of the postal and courier services. Using corrugated cardboard material, postal boxes are available in standard or bespoke sizes. Cardboard postal packaging is typically lightweight, low-cost, and easy to recycle.

At GWP, our custom mailing boxes can help you reduce postage costs by minimising weight and volumetric size. Your postal boxes can adhere to Royal Mail pricing in proportion (PIP) guidelines and feature printed branding and instructions. And by working with us, you can also source the rest of your postal packaging, including void fill, tape, poly mailers, tubes and other sundries, from a single source.

More info on cardboard postal packaging

Selecting the right postal boxes can reduce your shipping costs and help minimise product returns caused by transit damage. Most postage boxes are available in single—or double-wall material, so you can choose an option that provides suitable performance and protection for your goods.

Besides bespoke sizes and materials, several other options are available to enhance your postal packaging.

Options include exterior branding, logos, and handling instructions. A range of inserts, dividers, and void fill is also available. These inserts allow for improved protection as they eliminate movement within the outer container. They can also improve your efficiency, packing speeds, and inventory management.

Postal box FAQs

What are postal boxes?

Postal boxes are a form of single-trip packaging used for shipping products, goods or orders from your business to your customers. Usually manufactured from corrugated cardboard, postal boxes are available in various styles and sizes and offer several custom options.

What is the difference between postal, mailing, and shipping boxes?

Essentially, nothing. Postage boxes, mailing boxes, shipping boxes, and even postal packaging are all interchangeable terms for the same product type. However, due to the number of options (sizes, styles, materials), it is possible to create many variations within this broad categorisation.

Can mailing boxes be printed?

Printing your postal boxes is surprisingly cost-effective. Printing can add simple company logos and branding, handling instructions and health and safety information. You can even wow your customers with full-colour graphics that are only revealed upon opening the package (creating a unique unboxing experience).

What grade of cardboard do postal boxes use?

The grade of cardboard used to manufacture postal boxes can and should vary depending on the type and weight of the products you are shipping. One advantage of specifying bespoke postage boxes is that the material can be matched to the intended application. For example, lightweight products like clothing may only require a single-wall material, whereas heavier items may need double-wall boxes.

What are BDC and BDCM boxes?

BDC stands for “Bulk Distribution Carton”, whilst BDCM means “Bulk Distribution Carton Metric”. These are effectively a range of standard-sized boxes used for shipping items. Traditionally used in mail order, catalogue, fashion and retail applications, they usually include a printed area allowing the contents to be marked using a pen or label.

What are PIP boxes?

PIP stands for “pricing in proportion”. This terminology relates to the pricing structure Royal Mail introduced in 2013. Postal boxes of certain sizes qualify for specific pricing bands. As a result, it is possible to specify PIP mailing boxes that meet the large letter, small parcel, medium parcel or large parcel requirements.

Should I use stock or bespoke postal packaging?

Whether you should use stock or bespoke postal boxes depends on various factors, including your application, the volume of parcels you send, and the types of products you ship. As a rough rule of thumb, stock boxes are usually best if you only use low volumes or must adhere to specific industry guidelines or sizes. Custom packaging usually provides better performance, is frequently cheaper in the long run, and can offer numerous other benefits.

Can mailing boxes be customised?

You can customise any postal boxes sourced from GWP in several ways. Options include print and a range of inserts, dividers, fittings, and even foam cushioning. These can allow for more efficient packing, better protection for your items in transit, and improved presentation.

Is it possible to buy single or low-volume postal boxes?

Focusing on supplying business packaging means that GWP cannot supply one-off or low-volume orders. For such requirements, we recommend buying stock products from an online shop. However, if you are in any doubt, please ask. A GWP expert can advise you on the best option for your specific application.
