BSW Machinery, the Vienna based subsidiary of Windmöller & Hölscher, has introduced its new technology for woven PP bags. The technology combines several developments, which together allow the reduction of bag weight without losing any of the performance criteria. Key elements are advanced extrusion technology for higher tape tenacity and indexed micro perforation. Reduced weight leads to lower bag cost and improved sustainability.
The new Light & Strong technology (LS) will allow bag producers to reduce their material usage. Critical areas of the bags are made stronger compared to older technologies, the overall thickness and weight of the bag material can be reduced while maintaining current strength.
For cement bags 80g/bag are quite common. BSW produced bags with 64g, filled with cement and performed drop-tests with the result that LS bags excel conventional bags.
The new processing technology implemented on BSW’s tape extrusion line tiraTex allows for the great results even at highest outputs and production speeds of 500 m/min or more.
