Standard Royal Mail letter format and household letter boxes format

If you are looking for a rigid packaging solution that fits Royal Mail letter formats or household letter boxes, this is it.

All-in-one packaging solution, with self-adhesive closure

 Its self-adhesive closure let you pack quickly and easily, with no need for additional packing tape.

Made from micro-flute cardboard, this mailer box offers edge and lateral protection, ensuring that your documents, photographs or stationery products will arrive safely to your customers.

100% recyclable boxes made from recycled paper

DS Smith is a leading supplier of sustainable packaging solutions. We produce boxes for our customers, collect them once they have been used, and recycle them back into more boxes. It takes only two weeks for paper fibre to move around our business, and we handle over 5 million tonnes every year. That is the weight of 25 000 jumbo jets! 



One of the most important principles of the circular economy is designing for circularity, which involves products and services being designed with their end-of-life in mind, making it easier to recover and regenerate materials.

DS Smith has developed a series of circular design metrics which give us an accurate picture of the degree of implementation of circular design principles in the production of our packaging solutions and provide quantifiable data to show how circular a given packaging solution is and allow quick identification of the areas of improvement required.

Our Circular Design Metrics measure Supply Chain Optimisation, Recyclability, Planet Safety, Material Utilisation, Renewable Sources, Recycled Content, the Carbon Footprint and Design for Reuse.

* This circularity information was made by using the information of a average mailer box.
