Flow Pack (HFFS) - FV 35 Flow Wrapper

Horizontal FLOW-VAC® type Flow Wrapper (HFFS) that forms a vacuum pack from a single shrink and barrier film. For processed and smoked meat as well as cheese. It is also a suitable machine for pork and lamb meat.

Flow Pack (HFFS) - FV 35 Flow Wrapper


The FLOW-VAC® system has been developed by ULMA Packaging to create a vacuum shrink bag around the product to be packed.

The new FV 35 system offers an entry level solution at a very competitive investment level, for those applications that require the automation of the vacuum packing process.

The ULMA FV 35 machine is a bottom reel packaging machine, that feeds the barrier roll stock film beneath the level of the product feeding line. The barrier film unwinds off the reel as the product moves into the longitudinal seal head system, which prevents the transverse seal being contaminated as the product does not come into contact with the seal area.

The vacuum bag is formed around the product and a full hermetic seal is formed along the length of the bag (longitudinal seal). All excess material from the longitudinal seal is removed from the package via a film scrap removal system. This provides a shrink bag with excellent aesthetics as a result of the narrow longitudinal seal.

The FLOW-VAC® system senses the beginning of each product and indexes the incoming product automatically. The end seal (transverse seal) is a very reliable high quality, fully hermetic seal.

Designed for the Fresh Food industry, fully manufactured in Stainless Steel, the FV 35 is the perfect solution for the automation of the vacuum packing process while offering a high level of flexibility.


  • High flexibility.
  • Process automation.
  • Increased productivity.
  • Less material usage.
  • Reduced labor requirements.
  • Less seal contamination.
  • Less vacuum leakages.




Using patent-pending technology, ULMA has developed a simple but brilliant solution to automate the feeding of a belt vacuum chamber on both sealing bars. Packages are sealed only on one end and prepared to be transferred to the buffering belt of the vacuum chamber with the open end facing both seal bars on the vacuum chamber. A 90° transfer system pairs the packages to the buffering belt of the vacuum chamber so that both seal bars can be utilized. If the products are not small enough to be paired, an auto-detect system will load the product as a single item. This automated system increases productivity and reduces labor costs. The packaging system is ideal for the meat and cheese industry.
