ULMA Packaging Presents Flex Set: The System That Simplifies Pressure Adjustment in Flow Pack Rotary Jaws

Jan 13, 2026
ULMA Packaging has introduced a new advancement in its Flow Pack solutions aimed at enhancing machine operability and flexibility for systems with rotary jaws: the Flex Set system. This innovation addresses a recurring need in packaging lines that work with materials of varying thicknesses, where precise pressure adjustment between jaws is essential to ensure optimal sealing.

Until now, pressure adjustment between jaws was a mechanical process performed manually, requiring the intervention of experienced personnel trained specifically in Flow Pack packaging equipment. This has typically limited the flexibility of rotary jaw machines when working with materials of widely varying thickness.

Flex Set Eliminates Adjustment Complexity

The new Flex Set system offers a direct solution to this challenge. Its design allows operators to control system elements via actuators integrated into the machine, enabling pressure adjustment between jaws that is:

  • Fast
  • Simple
  • Repeatable
  • Reliable
  • Tool-free
  • Does not require advanced mechanical or maintenance knowledge
  • Requires no disassembly of components

Additionally, an on-screen display on the machine’s HMI provides recommended actuator values based on the thickness of the film being used, facilitating precise and repeatable adjustments.

Direct Benefits to Productivity

Implementing the Flex Set system in your Flow Pack packaging machine offers significant advantages in day-to-day operations:

  • Greater flexibility to work with a wide range of materials, from thin plastic films to paper-based solutions
  • Simplified operations when switching to a new film
  • Reduced changeover times, allowing for more frequent adjustments when needed
  • Increased operational efficiency by enabling quick and easy changes between films with very different properties, maximizing return on investment
  • Improved machine availability and reduced downtime

With Flex Set, ULMA Packaging reaffirms its commitment to developing technologies that simplify operations, improve efficiency, and enhance the versatility of Flow Pack packaging lines.
