Cardboard mailing boxes
Custom postal boxes are a cost-effective option if your business sends eCommerce orders, mail-order goods, or even supplies to retail outlets.
Postal boxes protect goods throughout the various touchpoints of the postal and courier services. They can also minimise costs by reducing weight and volumetric size, adhere to Royal Mail pricing in proportion (PIP) guidelines and feature printing.
At GWP, we tailor virtually every product you source to your specific requirements. Whether this is the size, style, inserts, print or other customisation options, your custom postal boxes provide the optimum level of protection for your products. This approach also ensures you receive genuinely cost-effective pricing as you don’t pay for materials or features you don’t need.

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.
Can mailing boxes feature printing?
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 type 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 a packaging designer can match the material 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 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 requirements for large letters, small parcels, medium parcels, or large parcels.
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.
