HFFS Flow Wrapper

The VR-8 Master is classed as a Horizontal Form Fill and Seal Flow-Pack system. A HFFS system can create a self-contained package by first feeding a laminated film from the upper spool into the forming tunnel. The forming tunnel is universally adjustable allowing for varying sized packs to be created with a single machine. As the film is fed through the forming tunnel it is folded over, creating a tube. A seal is then welded along the length of the pack. As the newly formed package moves through the rotary seal head (head cutter) seals and cuts the ends to form a fully enclosed package. The VR-8 Master can use a wide variety of films for the heat-welding process.

The VR-8 Master’s advanced design and easy controls allow it to carry out complicated tasks quickly and efficiently. The VR-8 Master’s large forming tunnel allows for a variety of packs sizes ranging from 100 mm. x 10 mm. to 420 mm x 300 mm. A state-of-the-art Programmable Logic Controller and easy to use touch display makes programming an ease with the ability to store up to 40 different packs.



VR-8 Master Features


VR-8 Master Features

RGD Flow Wrappers are composed of a variety of parts from multiple electro mechanical groups. These components work together to produce a perfectly coordinated HFFS packaging platform.


  • The VR-8 Master utilizes a plastic-coated chassis that consists of a stand that holds two motors fixed in place, side panels and upper plates.
  • All of the VR-8 Master’s metal parts are all heat-treated and are painted with environmentally friendly power coated paints (epoxy)
  • The VR-8 Mater can be easily washed and is certified for use with food products
  • All the parts that come into contact with the product are stainless steel or food grade materials
  • The VR-8 Master comes with a set of tools for cleaning and maintenance and an instruction manual. A spare parts kit that consists of the most frequently needed spare parts will be quoted at time of sale


  • The VR-8 can produce up to 80 bags per minute depending on the type and size of the product, the feeder and the type of film being used.
  • The VR-8s speed is adjusted by the easy to use controls on the touch-screen

  • Touch-Screen HMI allows for operation of the main controls and provides a heads-up interface that indicates any error alarms
  • HMI is also used for the development and storage of up to for forty different packing recipes


  • The in-feed conveyor has a total length of 2000 mm. (6.5 ft.) and features stainless steel lateral guides that can be easily opened and cleaned. An optional in-feed conveyor that is 4000 mm. (13.1 ft.) is also available.
  • The removable pushers are made from high-quality plastic and are certified for use with food products
  • Product is transported by Teflon mats to avoid damages
  • The bottom opening of the in-feed conveyor is hinged to provide easy access for cleaning


  • The spool holder is self-centering and allows for easy film spool replacement
  • The VR-8 Master’s braking device is fully adjustable
  • The clutch plate gradually increases pressure as the film roll is consumed
  • Automatic double spool-holders are available as an add-on option if a label applicator is not installed


  • The VR-8 consists of three pairs of stainless sealing wheels
  • The electrical resistance system helps to avoid burning of the film, even when the machine is not running
  • The system is controlled by a digital temperature control with dual screen HMI for correcting asynchronies and reduces discrepancy to +/-2°C
  • The rollers resistance system is activated by solid state relays
  • The temperature control has multiple alarm signals to alert operators if issues arise
  • Greasing points are centralized for easy maintenance
  • The forming tunnel is universally adjustable for height and width


  • The Head Cutter includes cartridge style stainless steel resistances with a protective coating, which are guided by a digital heat control with dual display HMI system for correcting asynchronies and reduces discrepancy to +/-2°C using long-lasting solid-state relays
  • An easy to use electric button on the HMI is used to position the product with the head-cutter
  • The temperature control is equipped with several alarm signals
  • The cutting blade is fully adjustable
  • Greasing points are centralized for easy maintenance
  • The structure of the group is coated steel and the heat points are mechanically separated in order to allow for excellent heat dispersion
  • The pressure dampener is adjustable by two springs
  • The machine is equipped with safety devices to prevent damaging the mechanics. Sensitivity can be adjusted according to the product
  • The controls allow for variable widths and heights of the products

All flow wrap machines are constructed with painted or treated steel, stainless steel, and moulded plastic.


The VR-8 Master’s paints are composed of 70% resin and 30% inorganic pigments for colour. They have a density of 1.6 + 0.5 and are applied at a thickness of 50 micron. The paints are applied electrostatically in a powder coating process, after the surface undergoes a cleaning and treatment process.


  • Epoxy-polyester powder paints are highly resistant to corrosion, scratching, abrasion, absorption and impact
  • Excellent light resistance to prevent colour fading
  • Highly resistant to chemical agents and cleaning substances: detergents, acetic acid, ethyl alcohol, etc.
  • The pigments are nontoxic and do not produce waste during the painting process.  
  • Excellent degree of flexibility and adherence

Compliance with Standards

  • UNE 48235 Composition of the paint. resins and pigments.
  • ISO 7235-84 Resistance to fog, saline environments (corrosion)
  • UNE 48032-80 Paint adherence tests.
  • PNE 48250 Resistance to abrasion.

In compliance with the provisions prescribed in EC Directive on machines 98/37.CEE and following:

  • EN – 294
  • EN – 60204/1

Upon sale and installation of your VR-8 Master will be electrically certified for use in Canada. A Pre-start health and safety review or inspection and ultimately certification, remains the responsibility of the end user.
