A large percentage of Pp Woven Bags – 30 to 40 percent is produced with coating, this number is kept on rising this couple of years. Because coated sacks provide much better protection of the contents from dust and especially from moisture. Coated fabric also offers better printability.

Refer to the industrial packaging, a coated or bopp laminated woven bag plus the AD Star bag making machine, bring big benifits for the cement, putty, limestone, food ingredient… powdery materials.

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.

4. Star micro perforation system

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.
