At K 2025, Starlinger will show its extensive product range of AD*STAR block bottom valve bag for cement and other dry bulk goods, of which its latest variants include AD*STAR bags made from 40% post-consumer recycled material from used, recycled AD*STAR cement bags, as well as the diverse range of the AD*STAR *prime bag family.

Starlinger offers the technology for producing AD*STAR bags made from polypropylene fabric in a closed loop.

AD*STAR *prime

AD*STAR *prime bags offer enormous variety and flexibility in bag manufacturing. They can be produced in filling sizes from 5-118 liters, with high proportions of recycled polypropylene, and with various features such as sift-proof corners, inliner, anti-slip coating, and film lamination. An optional easy-open closure or carrying handles ensure convenient handling.

The bags cover a wide range of applications. Small bags laminated with printed PP film can be used in the consumer sector, while larger bags are popular in wholesale and industrial applications for packaging cement, chemical granulates, or foodstuffs such as rice and sugar.

AD*STAR bags show super strong but lightweight bulk packaging features. They protect well against moisture, and as double-layer versions, prevent dust formation. Being a mono-material packaging, they are also 100 % recyclable.

ad*starKON conversion technology

At K fair, Starlinger will show an ad*starKON SE bag conversion line in operation, which will produce AD*STAR bags. This model has been designed as a special edition to mark the recent installation of the 500th Starlinger ad*starKON SX bag conversion line and is only available in limited quantities.

Based on the successful SX conversion technology, the ad*starKON SE produces up to 120 precisely formed AD*STAR block bottom valve bags per minute and is characterized by easy-to-use “smart” production technology, and fast delivery times.

More packaging solutions at Starlinger in-house exhibition

Starlinger will present the latest developments in woven bag production at the company’s Open House in Weissenbach, Austria, ranging from AI-supported automation in tape extrusion and new possibilities in fabric lamination to the stacked pallet of bags at the end of the bag production process.

Starlinger will also present the latest generation of ad*starKON bag conversion lines at the Open House. The new ad*starKON CX, which will be unveiled for the first time in October 2025, combines the proven bag conversion technology with latest advances in process control – showing maximum automation, top production speeds, and an integrated quality management system.

Last but not least, the new pp*starKON X production line for pinch bottom bags made of polypropylene fabric will be on display at the Open House. The bags are with attractive design – counter-printed BOPP film laminated onto lightweight, high-strength PP woven fabric – and the pinch bottom closure, which is widely used in the end consumer sector.

Its excellent barrier properties offer reliable product protection, making PP*STAR bags particularly suitable for the packaging, transport, and storage of sensitive products such as animal feed or cereals.

The packaging is also designed for recycling – made entirely of polypropylene, and produced without the use of adhesives.

With a specially developed welding process, the pp*starKON X pinch bottom bag conversion line has been equipped with unique technological features, from the patented laser cutting system for the pinch closure to the innovative hot-air welding unit for closing the bag bottom or opening.
