CHINAPLAS 2012: Starlinger shows Conversion Line for AD*STAR Block Bottom Valve Sacks

After successful installations of AD*STAR sack production machinery in China, the Austrian Starlinger & Co. GmbH exhibits the ad*starKON 60 sack conversion line at the upcoming CHINAPLAS in Shanghai – a first-hand opportunity for bag converters to look at a fully automated process of sack conversion by means of hot air sealing technology.

Cost and material saving are important aspects in the production of packaging materials. High quality packaging that provides adequate protection for the content and at the same time is practical and cost efficient – this is the order of the day. The economical use of raw material, an extremely low breakage and spillage rate, as well as reusability and recyclability are factors that help to save money.

The AD*STAR concept meets those requirements by combining the best of three worlds: the brick shape and suitability for automatic handling of the paper bag, the tightness and flexibility of a PE film bag and the strength and resistance of a woven PP bag. Made of coated woven polypropylene fabric, the brick-shaped AD*STAR sacks are ideally suited to the high degree of automation which is characteristic for filling dry bulk goods such as cement, fertilizer and chemicals, or foodstuffs like rice and other grains. The woven structure lends them exceptional strength and reliably protects the packaged goods against spilling and moisture. And an AD*STAR sack weighs much less than the paper or polyethylene film sacks used in the same applications, which means that less raw material is needed for production.

AD*STAR hot air sealing technology: No glue needed

In addition to the material characteristics it is the production process that makes AD*STAR sacks special: They are produced without using glue. Instead, the coating on the fabric is plastically softened by applying hot air to bond the valve and bottom patches to the sack. The Starlinger ad*starKON conversion line combines state-of-the-art technology with outstanding flexibility and high reliability. With a production capacity of up to 60 sacks per minute and an efficiency of more than 85 % it achieves an output of 22 million sacks per year. Machine-oriented operation with touch screen, an integrated quality assurance system and semiautomatic roll changeover ensure a smooth production process with reduced waste and high efficiency. To avoid pin holes in the fabric, the conversion line is standard equipped with a magnetic transport system. An optional microperforation unit can be added for packaging highly aerated goods without product emission.
