VFFS Machines – The Complete Guide

VFFS machines are widely used in food and pharma filling industries. To meet your various business needs, VFFS machines can be used to fill different types of packaging bags such as quad seal bags, square bottom bags, gusseted bags, etc.

If you want to choose the right VFFS machine, this guide can provide you with important information in detail.

What is a VFFS machine?

VFFS machine

The vertical form fill seal machine (VFFS) is an automated packaging method commonly used on production lines. It works by wrapping a film into a tube, then filling it in the vertical direction with products, and finally sealing the top to create a complete package. This filling method is precise and efficient, creating convenient packaging that is easy for opening and storing of products. This machine is popular for packaging products like coffee, snacks, and medicines.

Types of VFFS Machines

Intermittent VFFS Machines

These machines are able to produce bags from film, fill and seal them, and then cut them to create complete packaging, continuously following this workflow. While slower in speed, these machines are easy to maintain. If you require packaging for dry or precisely weighed products and want to reduce costs, the Intermittent VFFS Machines would be a good choice.

Continuous VFFS machines

These machines batch-produce film into tubes and then continue along the production line for filling and sealing. They are faster than batch-filling machines, but they are also more expensive and more complicated to operate. They can be used to package liquids as well as pastes if efficiency is important to you.

Auger VFFS Machines 

These machines are commonly used for packaging coffee, spices, flour, protein powders, pharmaceutical powders and other similar granular or powdered substances. 

Rotary screws can accurately dispense quantities of powdered as well as granular products into bags, and they are automated and efficient enough to process a wide range of sizes and materials. If you need a filling machine for food or pharmaceuticals, Auger VFFS Machines is a good choice.

Liquid VFFS Machines 

This machine has solid stainless steel fittings and features a servo-driven sealing system. The open design is easy to clean and maintain. Liquid VFFS Machines are easy to handle as they use a pump to fill the bag with liquid.

Crucial Components of VFFS Machines

Film unwind: This is where the entire packaging process begins. The film is unwound and fed into the machine. The material of the film varies depending on the packaging product, usually made of materials like polyethylene or polypropylene. The thickness and size of the film can be customized according to your needs. Our machines can accurately control the extent to which the film is stretched, which is crucial for ensuring strong and visually appealing packaging.

Forming Tube: The forming tube shapes the film into a tube, typically by using heat to seal the edges of the film.

Product filler: VFFS Machines are equipped with different filling systems, such as auger fillers, volumetric cup fillers, or multi-head weighers, etc., based on the characteristics of the product. Our filling machines can precisely ensure that each package contains the right amount of product.

Sealing jaws: Seal the bag with horizontal or vertical sealing pliers to ensure a tight seal and ensure the freshness and integrity of your product.

HMI(Human-Machine Interface): Our VFFS Machines are equipped with a control panel, making it easy for operators to set and adjust various parameters such as filling volume, machine speed, etc. The HMI can also store multiple packaging recipes.

Working Process of VFFS Machines

Film unwinding: The film is unwound and fed into the machine.

Forming of the Bag: Pull the film down and form into a tube shape through vertical sealing, and then the bottom of the tube is sealed to create a bag.

Filling: Filling the product into the packaging bag through a product chute, to the required quantity.

Sealing: The top is sealed, forming the product packaging.

Cutting: Excess film is trimmed off to create individual finished packaging.

Discharge: The packaged products are removed from the machine, and then prepared for the next steps, such as boxing or labeling.

Applications of the VFFS machine:

Food industry: VFFS machines are capable of packaging snacks, candies, coffee, grains, etc. These machines can handle various types of packaging materials.

Pharmaceutical and medical packaging: VFFS machines are used in the pharmaceutical industry to package tablets, capsules, powders, and granules. These machines can ensure accurate filling and sealing integrity, which is crucial for pharmaceutical packaging.

Pet Food: VFFS machines can be used to package pet food, including coarse-ground food and treats. They are capable of handling bags of various sizes and materials, making them highly suitable for this application.

Chemical and industrial products: VFFS machines can meet specific requirements, making them suitable for packaging various chemical formulations and industrial products.

Personal Care and Cosmetics: VFFS machines can package personal care and cosmetic products such as powder, wet wipes, and creams in various types of packaging bags, providing a hygienic and efficient filling method for these products.

Hardware and Fasteners Packaging: VFFS machines are used to package small hardware components, fasteners, and small parts across different industries. They can handle different styles of bags and are highly efficient.

The high efficiency and automation features of VFFS machines have made them widely used in the filling industry. Their exceptional performance in handling different materials and styles of packaging has made them an essential part of the filling industry.

Common Formats of VFFS machines

Pillow Bag: A type of packaging usually used for snacks, candies, and pastries.

Gusseted Bag: This format is used to make bags with corner support on each side, providing a larger, more secure fill volume. These types of bags are commonly used for pet food and items like rice.

Quad Seal Bag: Bags with four separate side panels and a flat bottom, providing enhanced stability for packaging. Typically used for packaging coffee, tea.

Stick Pack: This format is used to produce long and narrow single-serve packaging. They are commonly used for packaging powders, granules, or liquid products, such as medicines.

Sachet Format: Used for producing small sealed packages, usually used to package seasonings and spices.

The different filling methods of VFFS machines

Cup Filling: The cup filling system uses pre-determined cups to measure a specific volume of product and distribute it into packaging materials. It is commonly used for filling granular products. This machine is easy to use and has lower costs.

Auger filling: This method uses a rotating screw to measure and package specific quantities of powdered or granular products. This filling method is suitable for products such as flour and spices. The machine components for this method require regular cleaning and maintenance.

Counting filling: This method is typically used for individually wrapped products, such as candy or small hardware. This filling method saves you labor by using a machine to dispense a specified number of items into each parcel and also reduces errors.
