Bag or sack-like packaging

Abstract

The present invention refers to a bag or sack-like packaging, made of polymer material, idealized for packing, transporting and handling of solid powered and/or bulk materials, and provided with a detachable cover which, besides providing safety and guaranteeing the resistance required for transporting and handling the loaded packaging, also enables the opening of the packaging by detachment of the cover, without making cuts or tears, so that the packaging can be reused.
