Treepac is a reusable shipping container intended to replace cardboard boxes for shipping. The pack is meant to be used like a cardboard box, but it is designed to enable and encourage people and companies to improve their personal environmental footprint. The more times each pack is used, the greater the positive effect on the environment. Designed from a systems perspective, Treepac addresses the specific needs of packers, shippers and recipients; it mirrors the good features of cardboard boxes, adds new features and enables new service concepts; and in use it yields a significantly lower overall environmental impact than recycled single-use cardboard boxes.
