Starlinger, Vienna, Austria, has introduced the IC*STAR sack concept which has been developed in association with Gleisdorf-based STATEC BINDER. With this new system woven polypropylene sacks are welded with a sealing band instead of being sewn at the bottom, giving advantages of enhanced strength, dust-tight closure and significant savings in materials.

 

“Closure of sacks by welding is the solution of the future for standard woven sacks,” said Starlinger’s sales director Hermann Adrigan. “Compared to sewing, the IC*STAR process offers considerable material savings in sack production, consequently requiring less raw material – polypropylene in this case. Sack producers profit from lower costs, and the reduced carbon footprint is good for the environment.” Material is saved by the elimination of the seam allowance required for a sewn closure, as well as by the use of lighter fabric made possible by the greater sack bottom strength. The oil-free production process makes IC*STAR sacks ideal for packaging foodstuffs.

 

These sacks are produced on the Starlinger multiKON KX sack conversion line equipped with the sealTEC bottom closure module, jointly developed by Starlinger and STATEC BINDER. The mouth of the bag remains open and can be closed after filling on the filling line, either by welding with another sealing band or by sewing. www.starlinger.com; www.statec-binder.at 

 

 

The sealing band ensures dust-tight closure and is welded on to the sack bottom by means of hot air, with no need for glue; the sealTEC module requires less maintenance than a sewing machine and needs considerably fewer replacement parts
