Frustration-free unboxing experience

You only have one chance to create a great first impression. In e-commerce, the first physical link between your business and your customers is your packaging. At DS Smith, we understand that a perfect customer unboxing experience is key to ensure customer satisfaction and reinforce the power of your brand.

With our mailers’ easy-opening tear strip, your customer can open the packaging quickly and safely, no need for scissors or knives. Even a child can open it easily – that’s why we call it a frustration-free unboxing experience.

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!
