Flow Pack (HFFS) - SIENNA Flow Pack Wrapper

The new SIENNA family is the result of ULMA's commitment to innovation and technological development. This ongoing process brings us a new family of machines with improved performance and ease of use.

The new SIENNA features all the strength, reliability, and ease of operation of ULMA machines. Added to these well known characteristics of ULMA, the new model also features a higher flexibility and versatility (as the sealing head is powered with an independent motor), together with a much easier operation thanks to its touch screen control panel.

The great flexibility, proven reliability and the innovative technology applied to the new SIENNA family turns this line into the ideal packaging machine for a very wide range of applications in the food industry, especially in the produce, meat, cheese,… sectors.
