AD*Star bag refers to a woven polypropylene small packaging bag that is filled using a valve. They are also commonly referred to as block bottom valve bags or PP woven valve bags or square bottom valve bags . They function identically to a multi-wall paper valve bag; however, only one layer of material is used, and no adhesives are required to seal the bag. AD*Star bags can also be produced with paper or PE layers if required. It is important to note while there are a few substitutes out there, AD*Star bags are widely regarded as the superior pp woven valve bag available on the market.
