The open house also featured live demonstrations of the coating line lamiTEC LX – including a fully automatic roll change at production speed – and the conversion line ad*starKON, which turns fabric into the well-known AD*STAR block bottom valve sacks for free flowing bulk goods such as cement or fertilizer. Optionally, a microperforation unit creates tiny holes for efficient aeration of the sacks. During filling, these holes allow the excess air to escape, while the content stays safely inside the sack. Today, more than 10 billion AD*STAR sacks are produced on Starlinger lines in more than 150 production plants every year.
