Horizontal FLOW-VAC® type Flow Wrapper (HFFS) that forms a vacuum pack from a single shrink and barrier film. For all type of food products. High performance level.

Flow Pack (HFFS) - FLOW VAC 55 Flow Wrapper


The Ulma FLOW-VAC® is a lower reel machine, with the barrier roll stock film being fed from below the level of the product feeding line. This is essential to prevent seal contamination.

The vacuum bag is formed around the product and a full hermetic seal is formed along the length of the bag (longitudinal seal). The FLOW-VAC® senses the beginning of each product and indexes the incoming product automatically. The end seal (transverse seal) is a high quality full hermetic seal. Both seal systems are equipped with the latest technology to provide the most reliable seals possible. All excess material from the longitudinal seal is removed from the package via a film scrap removal system.

The Ulma FLOW-VAC® operates at the speed of incoming product and reacts to any speed variation in the production line.

The electronic platform of the FLOW-VAC® series is PC based with modem link options. The FLOW-VAC® machine has been designed for user friendly film roll change over. Product setup parameters are controlled through an industrial PC and a touch screen. The software is a Microsoft Windows based graphic icon software.

The barrier film unwinds off the reel as the product moves into the longitudinal seal head system. This prevents the transverse seal from being contaminated as the product does not come into contact with the seal area.

Designed for the food sector, and manufactured from stainless steel, the FLOW VAC ® ensures that maximum hygienic conditions are maintained for all sectors of the food industry.

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.
