Key features

The SIG SureFill 40 is a single-lane, automatic web filling machine. The machine is capable of packaging extended shelf life (ESL), high-acid (HA), and low-acid (LA) products in 3- to 20-liter bag-in-box sizes. The filler is equipped with an Allen Bradley PLC interface utilizing panel view plus HMI. To ensure optimal process conditions, this interface system also includes optional visual warning indicators as well as a messaging system that displays fault condition(s) and can, if necessary, stop the filling operation. All product contact surfaces are constructed out of 316L stainless steel.


This system has optional visual warning indicators; a messaging system that displays fault condition(s) and, if necessary, stops the filling operation. In addition, if necessary, product may be automatically diverted away from the filler with messaging to upstream processing control.


This filler is of modular design and can be configured to address a variety of packaging and bag loading options: from flat drop to end loading configurations.
