Product Description:
Top Open Block Bottom Bags are designed with an open top, ready to be filled with your contents. Once

It boasts exceptional strength, along with resistance to water, adverse weather conditions, rough handling, and tearing. Moreover, it exhibits variable permeability and is both recyclable and reusable, making it highly appropriate for use in the pallet storage of brick-shaped packaging bags.
Manufacturing process
The unique charm of block bottom bags lies in their assembly process, where they are meticulously crafted using hot air welding, a method that eschews adhesives. Unlike other industrial bags, the base of these pouches is elegantly gusseted at the sides and securely sealed. Additionally, vertical sides are thoughtfully creased to ensure the bag stands firmly and proudly on store shelves. Typically, these top-open block bottom bags grace non-automated packaging stations, especially for products like chemicals, fertilizers, and plastics, which come in granular forms.
The Ad*Star® Bag, patented globally by Starlinger, is crafted with care exclusively on Starlinger machines. We are proud to say that we have been the leading Ad*Star Bag manufacturer since 2009 right here in China
