Vertical form fill seal machines produce pillow packs, three-side seals, four-side seals, and irregular-shaped or gusset sachets or pouches. These packs are automatically filled and vertically packaged before being hermetically sealed.
Our vertical form-fill-seal packaging machines cover various applications and can be customised according to your production needs. All individual unwinder, pouch former, and dosing-sealing modules that comprise our vertical form-fill-seal packaging machinery are available in different versions based on your production requirements.

Applications
Vertical form-fill-seal packaging machines are well-suited to pharmaceutical, confectionery, coffee, dairy, individually quick frozen, and chemical industries for the packaging of various kinds of leavened foodstuff, candies and snacks like peanuts and seeds, dried meats, pet food and treats, coffee, starch, other ground powder products, meat and poultry, etc.
Advantages
- Automatic edge guidance, film tracking, and centring drive systems.
- Simplified operation with bilingual, touch screen, programmable logic controller (PLC) control and automatic fault detection system.
- Excellent compatibility with most small and medium packaging lines.
- Minimal carbon footprint with standard electrical power supply.
- Modern, easy-to-clean stainless steel design.
- Specialised sealing bars with integrated temperature control for optimal sealing.
- Highly productive film drive system with packaging speeds of more than 60 bags per minute.
- The efficient exchange of forming tubes allows for quick size change overs.
- Greater flexibility in packaging shapes and sizes, with adjustable packing speeds based on production needs.
How it works
Vertical form-fill-seal packaging machines feed a reel of polyethylene terephthalate (PET)/ polyethylene (PE), biaxially-oriented polypropylene (BOPP), or laminated packaging film over a forming tube to set the bag width for forming the film into the desired packaging size. Next, the bottom and vertical seals are applied where the two edges of the film meet. Finally, the bag length is automatically controlled through the machine’s programming, either by printed eye mark or set repeat length.
Since the vertical form-fill-seal packaging machines are synchronised to an auger, multi-head scale, or volumetric filler, dosing and filling are done automatically once a bag is available. Sensors relay when a bag is filled accurately before the top seal is applied and the bag is cut away. Depending on each package’s function, additional batch/expiration dates, tear notches, or hole punches may be applied.
