OUR EQUIPMENT
As the first company in China to improt the bottomer ad*starKON in 2009, we gathered rich experience in bag making and a deep understanding of differentiated bags in specific industries. Top equipment, 100% virgin Polypropylene material, more than 30,000 metric tons annual throughput. That provides a reliable guarantee for the subsequent production of high-quality packaging bags.
About Block Bottom Bags
AD* Star is the well-known bag concept for powdery material - in use worldwide, patented internationally, and produced exclusively on Starlinger machines. The brick-shaped PP woven bags, produced without adhesives by heat-welding of the coating on the fabrics, were developed with automated filling and landing processes in mind. As a result of the material characteristics and the special production process, the weight of an average 50kg block bottom cement sack can be as low as 75 grams. A comparable 3-layer paper bag will weigh about 180 grams and a PE-Film bag 150 grams. The economical use of raw materials not only helps minimize cost, it is also a valuable contribution to the preservation of our environment.
