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, 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 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 material not only helps minimize cost, it is also a valuable contribution to the preservation of our environment.

Applications
The Block Bottom Packaging Valve Bags are widely used in industrial packing for powder and grain: As cement bags, putty bags, gypsum bags, calcium bags, fine chemical bags, and rice bags, flour bags, etc.
The top opened the bag with block bottom is more widely used by fertilizer, grain & seed, stock feed, animal nutrition, etc.
Key Benefits
1. Light
The trend in packaging materials goes towards reducing their weight: less weight means less material consumption.
2.Strong
The challenge in reducing the weight of bag material is to maintain its important properties such as fabric tensile. Fed by 100% virgin polypropylene material, and extruded the tape by Starlinger equipment, which can make sure the tape in thinness, high strength, excellent durability, and great breaking resistance. An average single-layer PP Block Bottom Valve Bag that holds 50kg of content weights only 70g - a weight reduction of more than 55% compared to a 3-ply paper bag of the same size.
3.Environment-friendly
The Block Bottom Valve Bag uses nanoneedle which has 64 holes per 1 cm² for air permeation. The bag after filling with 50kg cement drops from 1m high for 8 times, only lose 20g. Considering its environment-friendly, extremely lower breakage rate, and cost-effective features, more and more powder plants choose this bag for packaging their products.
4.Reduce Space through Higher Stacking
Due to the perfect rectangular shape, block bottom bags can be stacked high using space efficiently. And can be used in both manual & automatic loaders.
Fits perfectly with palletizing or truck loading equipment, as it is the same size as other sacks made from different materials.
Our main products are PP woven bags, Bopp laminated bags, Ad*Star block bottom bags, and big bags/Jumbo bags etc., all of them are highly sophisticated products.
