Flexible Bag Closers
The USC-300 static sealer closer is designed to enable manual sealing and closing of pre-glued fold-top bags in low volume production plants.

Sealer Closer - USC-300

USC-300 Operator Controls
The GEA ultrasealer closer (USC-300) is a compact sealing and closing system for use with step-top multi-wall Kraft bags that have a polyethylene (PE) inner bag. For bags without an inner liner, the USC-300 can be used as a bag/sack top fold/closing system,making it versatile flexible solution for most customers’ needs.
This sealer/closer is designed for static operation where the bag rests on a roller conveyor or platform where the operator can manually control the bag throughout the handling and closing process.
Bags are manually presented to the sealer for semi-automatic sealing and closing operation using either a foot-switch or push-button control. Solid state control provides a reliable but flexible operation to suit a wide range of bag types. Temperature control is provided for both inner liner seal and to reactivate the pre-applied glue strip. Height adjustment is provided to ensure safe operation and to match existing bag handling equipment.

The new GEA Application and Technology Center (ATC) in Sarstedt, south of Hannover, is neither a showroom nor a substitute for a lab. It is a place for testing, data collection and early decisions. This is where it becomes clear whether a biological concept can become a robust industrial process. That step is bigger than it may seem.

Thermoforming has long played a central role in food packaging. Now it is facing a major shift. As regulations tighten, materials evolve and costs rise, form fill seal lines must do more than run reliably – they now shape how food stays fresh, affordable and recyclable. Take a look at the key thermoforming trends informing the food packaging and delivery landscape.
