AD Star Bags: The Ultimate Packaging Solution
AD Star Bags, also known as block bottom bags, are renowned for their superior strength and durability. Manufactured with a circular woven PP tube, these bags undergo a unique adhesive-free heat welding process that ensures exceptional tear and break resistance. Patented worldwide by Starlinger, our AD Star Bags are made from high-quality polypropylene fabric, making them the best choice for secure and reliable packaging.






Superior Construction and Design
Our AD Star Bags are crafted using state-of-the-art technology. The woven tubes are laminated with a mixture of polypropylene and polyethylene film, providing additional strength and protection. These laminated tubes can be printed and perforated, offering versatility for various packaging needs. During the final production step, the laminated, printed tubes are cut to size on an AD-CONVERTEX production line, and the bags are converted by thermofixing the top, valve, and bottom patches.
Exceptional Printing and Customization
We achieve top-notch print results with flexo-printing on one or two sides in up to four colors. The top and bottom patches can also be printed, enhancing brand visibility and appeal. Coating options with a matte or shiny finish are available in different colors to match your specific requirements. Additionally, the bags can be perforated, UN-certified, or supplied in food-approved quality upon request.
