AD*STAR® bags

AD*STAR® is the renowned block bottom sack made without adhesives from coated polypropylene fabric – patented worldwide by Starlinger and made exclusively on Starlinger machines. The sack can be produced either as a one-layer block bottom valve bag or as an open mouth bag with a block bottom. It surpasses all comparable products as far as resistance to breakage is concerned, is versatile and also eco-friendly and economical.

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 75g. A comparable 3-layer paper bag will weigh about 180g and a PE-film bag 150g. An economical use of raw material not only helps minimize cost, it is also a valuable contribution to the preservation of our environment.
