Starlinger, Vienna, Austria, points out that its AD*STAR® block bottom valve sack offers many advantages compared to alternative sack designs. Produced in a heat sealing process from coated polypropylene woven fabric, it is said to outperform all comparable products in terms of break resistance and durability, whilst also being versatile, economical and environmentally friendly. These claims have been borne out by a recent life cycle analysis, in which AD*STAR sacks scored better than either sewn cement sacks made from polypropylene tape fabric or paper cement sacks. This study, which compared AD*STAR cement sacks with cement sacks from China (sewn sacks made of recycled woven PP tape fabric) and Saudi Arabia (paper), shows that AD*STAR sacks have the lowest negative greenhouse potential of them all. Also by other criteria such as acidification potential, ozone depletion potential, energy and water consumption, they were demonstrably the most eco-friendly.

 

“A changeover to AD*STAR sacks for cement packaging would be of special interest to China,” said Hermann Adrigan, sales director of Starlinger. “Not only would it ease the impact on the environment by considerably reducing CO2 emissions, but using AD*STAR sacks would enable the automation of the entire chain of cement filling and transport processes to a much higher degree.” Starlinger will be exhibiting at Chinaplas, Guangzhou/China, 16-19 May, in the Austrian Pavilion, W1 B41. www.starlinger.com
