The best bottom valve bag manufacturer would not use any chemicals in the production of the bags. The bags we are providing have high tensile strength with amazing tear resistance. We make sure that every bag passing through our quality control is moisture free and there is absolutely no leakage at the bottom due to the valve.

Block valve bag is known for allowing stable and large stacking volumes; therefore, it is largely used in the packing of concrete materials, polymers, granules, resins, and PVC compounds. Pp Woven Bags also have a market in animal feed, cattle feed stock, fertilizers, urea, salt, and minerals industries.

Technical of the AD*Star Block Bottom Valve PP Woven Bags

1. Hot air Welding, no stitch, no hole, no adhesive.

2. More Environmental protection.

3. Production capacity may get 1.5 million per week.

AD*STAR® is the well-known sack concept for cement – in use worldwide, patented internationally, and produced exclusively on Starlinger machines. The brick-shaped PP woven sacks, produced without adhesives by heat-welding of the coating on the fabrics, was 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 50 kg AD*STAR® cement sack can be as low as 75 grams. A comparable 3-layer paper bag will weigh about 180 grams and PE-film bag 150 grams. An economical use of raw material not only helps minimize cost, it is also a valuable contribution to the preservation of our environment.

The Ad*Star Sack can be produced either as a one-layer Block Bottom Valve Bag (V-BB) or as an open mouth bag with a block bottom without valve (OM-BB) and with or without micro-perforations.
