What Are AD*STAR Bags?
AD*STAR® bags are block bottom polypropylene sacks produced using Starlinger technology. They combine the strength of woven polypropylene with the stable, brick-shaped structure of a block bottom bag.
The bags are available in valve and open-mouth constructions and are widely used for packing dry bulk products such as cement, dry mortar, wall putty, tile adhesive, fertilizer, minerals and other powdered or granular materials.
Compared with conventional sewn PP woven sacks, the block bottom construction provides a more stable shape for filling, palletizing, stacking and transportation.
ULINK® PACK manufactures customized PP block bottom bags using Starlinger bag-making equipment, with options for different sizes, capacities, printing, lamination and bag constructions.
