Woven sacks sealed completely tight with welded closure strip

23-Mar-17

In keeping with the motto “Sewing is the past”, Starlinger & Co. Ges.m.b.H. will feature live production at Interpack of IC*STAR (I = Innovative, C = Closing) sacks. These are produced on the new conversion line multiKON KX, equipped with the sealTEC bottom closing module developed by Starlinger in co-operation with the Austrian packaging systems manufacturer Statec Binder. The IC*STAR method involves the welding of a closure strip onto the sack bottom by means of hot air in a continuous process, without the need for glue. The sack mouth remains open and, after automated filling, can be either closed with another closure strip or sewn shut.

“The big advantage of IC*STAR sacks is that, unlike sewn sacks, they are sealed completely tight with the welded closure strip,” explains Hermann Adrigan, sales director for Starlinger. “The IC*STAR construction also practically eliminates the seam allowances required for sewn sacks, and greater strength in the sack bottom enables the use of lighter fabric. Both factors add up to cost savings in raw material – in this case polypropylene – and a reduction of the carbon footprint. Our customers are sensitive to these arguments.” The new process lends itself to production of coated or uncoated IC*STAR sacks, as well as sacks with gussets. Oil-free production makes them ideal for packaging food products such as rice, coffee, salt, sugar or flour in bulk quantities.
Since the official market launch last October at the K exhibition in Duesseldorf, the first IC*STAR conversion lines have already been delivered and installed.
