Choosing the right packaging machine is one of the most important decisions for any manufacturer. The wrong equipment can reduce efficiency, increase operating costs and limit your production capabilities, while the right machine can improve productivity, minimise waste and deliver a professional finished product.
Two of the most common automated packaging systems are Flow Wrap machines and Vertical Form Fill Seal (VFFS) machines. Although both package products using roll stock film, they are designed for very different applications.
If you’re comparing Flow Wrap vs VFFS, understanding the differences in product suitability, packaging style, speed and flexibility will help you invest in the right solution for your production line.
In this guide, we’ll explain how each machine works, compare their advantages and help you determine which packaging system best suits your business.
A Vertical Form Fill Seal (VFFS) machine creates bags from a roll of packaging film, fills them with product and seals them in one continuous automated process.
The packaging material is fed vertically over a forming tube, creating a bag that is filled before being heat sealed and cut.
VFFS machines are commonly used for loose, granular, powdered or free-flowing products, including:
These are just a few examples of the many applications of VFFS machines across the food, agriculture, and industrial packaging sectors.
Because different filling systems can be integrated with the machine, VFFS equipment offers exceptional versatility for manufacturers packaging multiple product types.
If you’d like to learn more about how this technology works, read our guide to What Is a VFFS Machine?
A Flow Wrap machine, sometimes called a horizontal flow wrapper, packages individual products by wrapping film around them horizontally before sealing both ends.
Unlike a VFFS machine, the product already has its final shape before entering the packaging machine.
Products move along a conveyor where packaging film is wrapped around them. A longitudinal fin seal is created underneath the product, while cross seals close both ends of the pack.
Flow wrapping is ideal for products such as:
Flow wrap packaging is widely used in retail environments where product presentation is important.
Although both machines automate packaging, they solve different production challenges.

When comparing packaging formats, it’s also important to understand the difference between vertical and horizontal systems, which we break down in VFFS vs HFFS packaging machines.
VFFS equipment is designed for products that need to be measured before packaging.
Examples include:
Because the machine forms each bag as required, manufacturers can often change bag sizes and packaging formats with minimal adjustments.
Flow wrapping is better suited to products that already have a defined shape before packaging.
Typical examples include:
Flow wrapping creates attractive retail-ready packaging while protecting products during storage and transport.
One of the biggest advantages of VFFS equipment is the variety of bag styles available.
Common VFFS packaging formats include:
Flow Wrap machines generally produce:
If your business requires multiple bag styles or frequent product changes, VFFS systems usually provide greater flexibility.
Both packaging systems are capable of high production speeds, although they are designed for different applications.
Flow Wrap machines often achieve extremely high output when packaging identical products continuously, making them popular in confectionery and bakery production.
VFFS machine speeds vary depending on:
For many manufacturers, the correct comparison isn’t simply “Which machine is faster?” but rather “Which machine packages my product most efficiently?”
One of the biggest advantages of automated systems is efficiency — and we explore this further in how VFFS machines beat manual packaging.
If production flexibility is a priority, VFFS machines generally have the advantage.
By changing the dosing system, a single VFFS machine may package products ranging from powders and grains to frozen foods and hardware components.
Depending on the machine specification, businesses can also change:
Flow Wrap machines are designed around products that already have a consistent size and shape. While they perform exceptionally well within those applications, they are generally less versatile when product dimensions vary significantly.
Factory floor space is often limited, particularly for growing manufacturers.
Because VFFS machines operate vertically, they usually occupy a smaller footprint than Flow Wrap systems.
Flow Wrap machines require:
As a result, they generally require a longer production line.
For facilities where space is at a premium, a VFFS machine may be the more practical solution.
The total investment depends on several factors, including:
Rather than comparing purchase price alone, manufacturers should evaluate the total cost of ownership, including:

A VFFS machine is generally the better choice if you package:
It is also ideal if you require:
A Flow Wrap machine is usually the better option if you manufacture:
It is particularly effective where attractive product presentation and high-speed packaging are essential.
Choosing between flow wrap and VFFS depends on product type, speed requirements, and packaging format, all of which are covered in our VFFS buying guide.
Choosing the correct packaging equipment requires more than simply comparing machine specifications.

Flow wrap machines package products horizontally, while VFFS machines package them vertically. Each is ideal for different product types and packaging needs.
Generally, yes. Flow Wrap Machines often offer higher packaging speeds, especially for uniform solid items.
Both work for food, but flow wrap is preferred for items like bars or bakery products, while VFFS is great for snacks, powders, and grains.
Flow wrap machines are typically faster for packaging solid, uniform products because they operate in a continuous horizontal motion. Many systems can reach very high output speeds, making them ideal for large-scale production lines.
VFFS machines are better suited for powders, granules, and liquids because the product can drop into the bag vertically using gravity, allowing for efficient filling and sealing.
Both machines typically use rollstock flexible films, but the packaging format differs. Flow wrap machines create horizontal pillow packs, while VFFS machines form bags or pouches from the film before filling them.
VFFS machines generally require less floor space because they operate vertically. Flow wrap machines require a longer horizontal footprint due to their conveyor-based design.
VFFS machines typically offer more flexibility in bag styles, including pillow bags, gusseted bags, and multi-lane sachets, making them suitable for many product types.
Yes. Flow wrap packaging is often preferred for retail products such as chocolate bars, biscuits, and medical devices because it creates a clean, visually appealing package with consistent seals.
Yes. Both Flow Wrap and VFFS machines can integrate with equipment such as conveyors, multi-head weighers, filling systems, labeling machines, and coding systems to create a fully automated packaging line.
VFFS machines are often more cost-effective for bulk packaging because they efficiently produce bags directly from film and can handle loose products such as rice, snacks, coffee, and grains.
Yes. Many manufacturers use both machines in different production lines depending on the product. For example, a company might use flow wrap for snack bars and VFFS for chips or powdered products.
The best choice depends on factors such as product type, packaging format, production speed, available floor space, and budget. Consulting with a packaging specialist helps ensure the machine fits your production requirements.
No. Flow Wrap machines package individual products horizontally, while VFFS machines form, fill and seal bags vertically for loose or free-flowing products.
Neither machine is universally better. The right choice depends entirely on the type of product being packaged.
Generally no. Chocolate bars are better suited to Flow Wrap machines because they already have a defined shape before packaging.
No. Loose products such as rice are typically packaged using a VFFS machine with an integrated filling system.
VFFS machines generally provide more bag styles and packaging flexibility than Flow Wrap systems.
When comparing Flow Wrap vs VFFS, the best solution depends on your product rather than the machine itself.
If you’re packaging loose products such as grains, powders, coffee, pet food or hardware, a VFFS machine is typically the most efficient and flexible choice.
If you’re packaging individually shaped products such as biscuits, chocolate, soap or medical items, a Flow Wrap machine is generally the better option.
Selecting the correct packaging equipment can improve production efficiency, reduce operating costs and support long-term business growth.
If you’re unsure which solution is right for your operation, the team at SA Packaging Machinery can help you evaluate your production requirements and recommend the most suitable packaging system for your business.
