1990 marked the transfer of ownership of the box factory from the expert management of Giuseppe Desio to the thrilling and determined management of Edoardo Zaffaroni and his son Matteo.
The market showed appreciation for the products and services offered by the DE.LE.S. Box Factory, which – in the space of a few years – became an established presence in the production of cardboard packaging in the Lombard market.
In 1997, the owners decided to expand the field of action into the protective polyethylene foam packaging sector: this saw the creation of DELES Imballaggi Speciali, which soon became one of the leading players on a national scale.
