AD*STAR® is a well-known sack concept for cement – in use worldwide, patented internationally, and produced exclusively on Starlinger or Windmoller & Holscher machines. The brick-shaped PP woven sack, produced without adhesives by heat welding of the coating on the fabric, was developed with automated filling and handling processes in mind. The sack can be produced either as a one-layer block bottom valve bag or as an open mouth bag with a block bottom. It surpasses all comparable products as far as resistance to breakage is concerned, is versatile and also eco-friendly and economical.
PP fabric is laminated on a PP extruder and printed. This is then loaded onto the AD*Star conversion line. At the end of the production process, the tubular fabric becomes a sack. And it is the conversion line that gives the sack its final, individual form, cutting it to length, sewing it, and adding the desired closure type – or forming a brick-shaped AD*STAR® sack in a special adhesive-free heat welding process.
Today, the Indian market has a lack of suppliers for this bag and an increasing demand for superior packaging across all sectors.
