FSF equipment for liquid and semi-liquid products :

  • In-house on site in-line production and filling of bag-in-box.
  • Combines a high-performance, flexible, and reliable machine with a range of films with excellent mechanical and physical performance properties and a high-barrier tap for your ideal bag-in-box package.
  • Gentle filling process, hence less dissolved oxygen in bag and thus longer shelf-life.
  • Fill up to 10L bags at speeds up to 22 bags per minute with four fill heads or up to 30 bags per minute with six fill heads.
  • Line consists of bag-maker, fitment inserter, and rotary filler.

Sustainable solution:

  • Less volume of packing materials in transport and storage pre-filling (roll-stock film, taps and spouts, handles).
  • Rent your production line: Just in time packing.
  • Lower total cost of ownership than pre-made bags.
  • Manufacture your own bags from revolutionary film solutions + dedicated taps and fitments + handles.
  • Deliveries from a sole production site.

Advantages of FSF Technology

FSF technology combines a high-performance, flexible and reliable machine with a range of films with excellent mechanical and physical performances and a very high-barrier tap to manufacture and fill more competitive bags with outstanding oxygen barrier performances.

  • On-demand bag making eliminates the need for stocking one or more sku’s of pre-made bags.
  • Completely automatic equipment reduces labor, maintenance and repair costs.
  • Rotary filling increases fill speeds up to four times over traditional linear filling.
  • Two versions (single or double lines) suits different production volume requirements.
  • Positive-air enclosure equipment keeps contaminants out of both bag making and filling operations.
  • Specially designed cartoning system protects the bags at this critical packaging stage.
