STONEPAK was born in 2009 from the acquisition of the bagging equipment division at Graphic Packaging International, Inc. This acquisition allowed Premier Tech Chronos (PTC) to become one of the most important manufacturers of valve bag filling equipment and to offer new solutions to the chemical, mineral and food industries. 

In 2015, PTC integrated STONEPAK equipment into its product portfolio, continuing the tradition that has been passed down through Bates, St. Regis Bates, Stone Container, Smurfit-Stone, Altivity, Graphic Packaging and now, Stonepak.

If you own equipment from STONEPAK or its predecessors, Premier Tech Chronos offers complete after-sales service and original parts for these brands. As a result, STONEPAK equipment users now have access to a dedicated and specialized after-sales team with a global reach.
