Postal Boxes

Forms Plus stock a range of cardboard boxes that are ideal for e-commerce, mailing and fulfilment companies. Our postal boxes provide protection for valuable and fragile items, ensuring your goods are secure and arrive well presented. The boxes are lightweight but sturdy, offering a more professional and eco-friendly solution than mailing bags.

We stock a range of PiP boxes, designed to fit Royal Mail’s pricing-in-proportion size guides. Sizes include Small, C4, C5, C6 and DL (Large Letter) postal boxes, as well as Mini, Midi and Maxi (Small Parcel) postal boxes.

Our cardboard boxes are supplied flat packed to save on storage and are very easy to assemble. They are made from sustainable materials, fully recyclable and biodegradable.
