Specialist bagging systems

Despite the availability of highly sophisticated silo logistics, bags continue playing an important role in the distribution of bulk goods. Especially for applications involving small batches or the packaging of demanding products, the manufacturers of food tend to rely on bags because of their flexible use. When it comes to selecting the appropriate bagging system, the properties of the products to be packaged need to be taken into account. Free-flowing products such as vitamin powder make other demands on the bagging technology than do heavy flowing and/or powdery and dusty products such as starch. It is for this reason Windmöller & Hölscher has released Topas and Opal, two different form-fill-seal packaging systems specially geared to these applications.

Topas can be used to pack free-flowing goods in volumes from 5 to 50 kg. Net and gross weighing systems, gravimetric or volumetric metering, bypass hopper, dust removal capability, air evacuation, mitred corner sealing, edge sealing, carrying handle attachment and even explosion-proof design in full compliance with ATEX standards are the hallmarks of the extensive configuration spectrum this FFS system has to offer.

Opal is the specialty machine for the bagging of heavily fluidised products and products which tend to stick, bridge or clog as well as fine and dusty products. For these products needing controlled bagging with minimum entrapped air, the Opal, with its auger metering system in conjunction with under-level product feeding, is suitable for the said applications. After weighing, air evacuation elements ensure effective compacting of the fluidised products.

The application-oriented technology allows for a broad spectrum of demanding products to be handled reliably and with maximum economic efficiency, including chemical fine products as well as food, salts and minerals.
