With DualPack, the construction of the two-piece box enables smaller and thus more sustainable shipping packaging. For example, if the consumer in the corrugated packaging receives shoes that he has ordered for fitting in two different sizes, he can use the lid of DualPack for the return shipment. Cleverly designed, this can be folded in half, creating a new, smaller package. "Smaller packaging saves CO2 in the logistics process. As a packaging manufacturer, the design of intelligent shipping packaging with a sustainable positive effect on the environment is a focus of our development work, “according to STI Group Marketing Director Claudia Rivinius. The STI Group offers its customers tailor-made packaging solutions that meet the needs of consumers and retailers while saving resources. DualPack is also interesting for online retailers, as the consignor can cover several standard sizes with the packaging concept DualPack.
