AD*STAR® is the well-known sack concept for powdery material - in use worldwide, patented internationally, and produced exclusively on Starlinger machines. The brick-shaped PP woven sacks, produced without adhesives by heat-welding of the coating on the fabrics, was developed with automated filling and landing processes in mind. As a result of the material characteristics and the special production process, the weight of an average 50 kg AD*STAR® cement sack can be as low as 75 grams. A comparable 3-layer paper bag will weigh about 180 grams and PE-film bag 150 grams. An economical use of raw material not only helps minimize cost, it is also a valuable contribution to the preservation of our environment.
