Key features

The SIG SureFill 44 Duo is a dual-lane, automatic, web-fed filling machine.  The machine is capable of packaging ambient products in 3- to 24-liter bag sizes. The filler is equipped with a monitor interfaced to a programmable controller assuring conditions during filling operations. All product contact surfaces are constructed out of 316L stainless steel and food-grade construction.


This system has 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.

  • Capable of packaging ambient products
  • Airless fill pad reduces product splashing and foaming for superior protection from entrained oxygen
  • Equipped with a monitor interface to a programmable controller assuring process conditions
