Stratapac Packaging System

Stratapac is a patented system for the packaging of powdered products to be used in hygienic processing environments.

The system utilizes a tough, two-ply plastic sack that replaces the traditional multi-ply paper sacks such as those currently used for export milk powders. Through the use of proprietary sealant resins and patented sealing equipment, the inner and outer bags of the Stratapac block-bottom sack are sealed independently and simultaneously. An easy-open perforation is applied to enable the fully sealed inner bag to be quickly and cleanly removed and taken into a hygienic processing area.

Through use of innovative co-extrusion and sealing technology, Stratapac combines the benefits of a removable, sealed inner bag with those of a tough, plastic outer bag. The resulting package provides improved hygiene and moisture resistance, better presentation, and a higher level of protection than conventional paper multiwall sacks. In addition, the system offers significant environmental benefits, with source reduction of up to 30% when compared with conventional 3-ply paper multiwall sacks. The outer plastic bag can be easily recycled. The inner bag can be designed with barrier or non-barrier properties utilizing Holmes Packaging 9-layer barrier co-extrusion technology. The outer bag is a tough 3-layer co-extrusion utilizing metallocene LLDPE resins.
