- Quality: With advanced servo motor systems, these machines offer high-speed, continuous operation. They are constructed to minimize waste and ensure consistent product quality.
3. Usage, Process, and Applications
A. Usage Across Industries
- Food Industry: VFFS machines are extensively used for packaging snacks, sauces, dairy products, powders, and liquids like milk and juices. They are critical for maintaining hygiene and extending product shelf life.
- Pharmaceutical Industry: VFFS machines provide precise dosing for powders and liquids, ensuring consistent product quality and compliance with regulatory standards.
- Chemical Industry: These machines handle chemicals and other corrosive liquids, offering flexibility with packaging options like back sealing and 3-side sealing to suit different products.
- Cosmetics Industry: For products like creams, lotions, and shampoos, VFFS machines automate the packaging process, reducing manual intervention and improving product consistency.
B. Process Flow
- Film Feeding and Bag Formation: The machine unwinds packaging film and forms it into a bag shape using forming collars.
- Filling: Depending on the product type (liquid, powder, granule), a suitable filling mechanism (plunger pump, valve pump, or auger) dispenses the precise quantity into the formed bag.
- Sealing and Cutting: The bag is then sealed using horizontal and vertical sealing bars, followed by cutting the filled bag from the film roll.
- Coding and Printing: Date codes, batch numbers, or other required information are printed on the bag. Optional features like ribbon printers ensure compliance with product labeling requirements.
- Delivery: The filled and sealed sachets are conveyed out for further packaging or collection.
C. Applications
- Liquids and Pastes: Ketchup, mayonnaise, shampoo, and dairy products.
- Powders and Granules: Coffee, spices, milk powder, pharmaceuticals.
