Working of Pouch Filling Machines from Nichrome
Pouch filling machines are becoming increasingly popular for industrial packaging across industries and across the world. Pouches tend to be flexible, lightweight and offer several advantages over traditional packaging such as metal cans or glass bottles.
There are generally two types of pouch filling machines: Vertical Form Fill Seal (VFFS) and horizontal form fill seal machines (HFFS), with VFFS being the preferred option.
Let’s understand the working principles of VFFS packaging machines:
Vertical Form Fill Seal (VFFS) machines are a kind of pouch making and filling machines that have a vertical structure. These machines are mainly used for industrial packaging and processing and provide a more convenient and effective method of automatic packaging which saves time, prevents material wastage and reduces cost.
Let’s look at the main components of VFFS pouch filling machines to understand the working of these machines:
Film Pulling System: This component of VFFS machines consists of an unwinding roller and tensioner. A roll of film – generally laminated PE, PET, aluminium foil – is placed on an unwinding roller – which is usually positioned at the rear of the machine. The tensioner and servo motors firmly and precisely unwind and pull the film into the system.
Printer (Optional): This component prints the date, production batch code etc on the film when it passes by the printer.
Pouch Former: The film moves to bag forming once the printing is done. The edges of the film are overlapped to shape the pouch while the top and bottom sealing is done by sealing jaws.
Filling and Sealing Machine: Filling is carried out by connecting
the bagging machine to a multi-head scale or similar filling machine – such as
an auger or volumetric filler. These two components are synchronized
electronically, so that as soon as the bag is ready, the product is released
The top of the bag is sealed once the product is dropped into it. The two parts of the overlapping material are pressed together and welded with heat using sealing jaws to create a side or centre seal.
Pouch Cut: Once the bag is sealed and filled, it is cut away. The top seal of the first bag becomes the bottom of the next bag ad infinitum. The cut pouch is dropped into a collection system – typically a belt conveyor that carries the pouch to the next step of packaging.
Control Cabinet: The side of the vertical form fill seal machine comes with a control cabinet inside which are all the electrical parts such as PLC, contactor, servo motors, pneumatic cylinder, solenoid valves, PLC expand mode, low-pressure electrical parts. The Human Machine Interface (HMI) makes operating and controlling the machine simpler.
