AD*STAR PP woven block bottom valve sack
AD*STAR is the renowned block bottom sack made without adhesives from coated polypropylene tape fabric, patented worldwide by Starlinger and made exclusively on Starlinger machines. The extremely low breakage rates and excellent protection against moisture of AD*STAR sacks sets them apart from conventional block bottom sacks. Packaging cement in AD*STAR sacks offers considerable savings potential regarding cement loss due to sack breakage or hardening in humid conditions: low breakage rates and good moisture protection mean that significantly less cement is lost in the logistic chain. Consequently, not only environmental pollution is reduced, but also less cement needs to be produced to replace these losses, which in turn saves CO2 emissions. For more sustainability, AD*STAR sacks can now also be produced containing high shares of recycled PP and CaCO3.
Worldwide, more than 30 billion AD*STAR sacks are produced on over 750 Starlinger lines in more than 60 countries.
