The cement sack of the future at Chinaplas 2017

When it comes to safe and sustainable packaging for bulk goods, there is no overlooking the Starlinger AD*STAR® block bottom valve sack. Produced in a heat sealing process from coated polypropylene woven fabric, this sack outperforms all comparable products in terms of break resistance and durability and is also versatile, economical and environment-friendly.

The latter has been confirmed 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 polypropylene tape fabric) and Saudi Arabia (paper sacks), shows that AD*STAR® sacks have the lowest 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,” says Hermann Adrigan, sales director of Starlinger, assessing the situation. “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. This would greatly benefit the ongoing modernisation on the Chinese cement sector.”

140 sacks per minute and more
AD*STAR® block bottom valve sacks are produced using a special heat sealing process on ad*starKON conversion lines from Starlinger. These lines achieve production speeds of 100 to 140 sacks per minute, operating on the basis of the heat sealing process patented by Starlinger. ad*starKON conversion lines feature a wide range of product options: In addition to block bottom sacks with or without valve, as well as lined and BOPP laminated  block bottom sacks, they can produce AD*STAR® *carry bags and REICO*STAR® block bottom sacks made of spunbonded fabric. Quick, simple and almost entirely automated format changeover offers sack producers maximum flexibility for the production of varying sack sizes and designs.
