The requirement for (VFFS) machines has gone up after Covid

Flexible packaging lines are gradually being replaced by automated machines and lines on account of industry demands such as lower production costs, better efficiencies, increased traceability, safety and hygiene, and first-rate convenient packaging. A vertical form, fill and seal (VFFS) machine plays a significant role in the packaging of goods and food items and is an integral element of such flexible packaging lines. As the demand for automation, remote maintenance, and networking increases, we describe a uniquely developed software integration solution developed by B&R India in Pune based on an interview with Prashant Rasal, who is part of the development team.

The quantum leap in the flexible packaging sector has immensely contributed to the growth of the VFFS equipment industry segment. According to recent industry estimates, the requirement for vertical form fill and seal (VFFS) machines has largely gone up after the Covid-19 pandemic due to the mushrooming pharmaceutical and FMCG segments. The VFFS packaging machine industry is expanding at a CAGR of >5 % over the forecast period of 2022 to 2029, as stated in a recent market study by Future Market Insights. The global sachet packaging market, covering sachets packaged by both Vertical Form Fill Seal (VFFS) and Horizontal Form Fill Seal (HFFS) machines, is currently valued at US$ 563.8 million (approximately Rs 4,300 crore). VFFS machines occupy an 88.5% dominant share in the sachet packaging market currently, which is likely to grow along with the growth of the solid and liquid packaging segment. 

Ideal for free-flowing, viscous, and granular goods, VFFS machines come in handy in industries such as chemicals, minerals, FMCG, pet food, and agriculture. VFFS machines support a wide range of pouch sizes and formats while significantly diminishing the risk of product contamination and satisfying food and product safety standards.

ospVFFS – automation software developed in India for Indians

ospVFFS is B&R Industrial Automation’s software solution aimed at the Indian food packaging segment. B&R’s out-of-the-box solution already has several built-in automation features for VFFS machines. A bouquet of automation software modules is available from which the machine builder or OEM needs to choose and apply those appropriate for his application or brand owner or packaging contractor customer. The software is scalable and can be adapted for all VFFS machine variants.

The brand owners initially provide specific parameters and data regarding their VFFS packaging lines such as their motors, load cells, cameras, and controllers in use. The ospVFFS team at B&R automation then customizes the software solution according to particular requirements of food brand owners. The software, developed in India for Indian customers, also offers remote maintenance.

The bespoke automation software offers several distinct advantages to food brands and packaging firms including marked engineering time reduction, along with short off-time before machine configuration. The food packagers can do away with the maintenance of different software for different machine variants and rely on the integration of multiple machines with a single point of automation.

B&R’s development team conducted in-depth research on VFFS machines and studied diverse customer requirements including machine models, machine variants, and challenges faced with current VFFS machines besides Industry 4.0 requirements. The automation firm gathered exhaustive inputs and feedback from machine builders, automation providers as well as end-users, and their packaging departments.

Prashant Rasal from the development team for B&R wants to focus on the Indian market’s intricacies

Prashant Rasal shares, “The ospVFFS is a single automation software solution for different machine variants. We are understanding the Indian market and its intricacies and accordingly developing our product.”

The mammoth challenge faced by VFFS machine manufacturers or OEMs today is to maintain numerous machine variant software simultaneously. Machines vary drastically in terms of multi-head weighers, infield conveyors, and the number of servo axis.

“We are helping customers to upgrade their machine level with our ospVFFS solution. The food brands don’t require engineering in their packaging lines, the customers can simply select their choice of options from the solution’s HMI or graphical user interface on the screen and the options will be adopted to the clients’ machine requirements,” adds Prashant Rasal, part of the technical development team for B&R ospVFFS.

Automation solutions in the making

The ospVFFS automation solution incorporates the pie charts for overall equipment efficiency. The running hours of the filling and sealing machine, the downtime, overall productivity, and efficiency are recorded and the inputs can be taken out in a PDF format in a pen drive. “We have tested the ospVFFS automation software on our clients’ machines and it is running successfully. Apart from that, we are giving a PackML machine state diagram when the machine is incorporated into a bigger line. With upstream and downstream manufacturing machines the PackML machine state diagrams can be communicated to other machines over OPC units as this software is OPC or Industry 4.0 complaint. The software also has a long history report feature which is 21CFR compliant,” Rasal explains.

“The next solution we are planning is for the multi-head weigher, a component of the VFFS machine. Almost 95 to 99% of the multi-head weighers used in the country are imported and the local machine manufacturers need more help from automation providers in the country. The Indian manufacturers have not yet found the right combination of multi-head weighers which can compete with the Chinese and Japanese manufacturers. 

“Although we are thinking of developing an automation solution specifically for multi-head weighers or liquid filling systems in the near future, we have plans to extend our automation solutions to other packaging machines. These could include HFFS, liquid filling system, and labeling machines which will be taken up after thorough consideration by our management in India,” Rasal concludes.

Packaging South Asia — resilient, growing and impactful — daily, monthly — always responsive

The multi-channel B2B in print and digital 17-year-old platform matches the industry’s growth trajectory. The Indian, South Asian, Southeast Asian, and Middle East packaging industries are looking beyond the resilience of the past three years. They are resuming capacity expansion and diversification, with high technology and automation in new plants and projects.

As we present our 2024 publishing plan, India’s real GDP growth for the financial year ending 31 March 2024 will exceed 6%. The packaging industry growth will match the GDP growth in volume terms and surpass it by at least 3% in terms of nominal growth allowing for price inflation in energy, raw materials, consumables, and capital equipment.

The capacity for flexible film manufacturing in India increased by 45% over the past four years. With orders in place, we expect another 20% capacity addition in 2024 and 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels are growing similarly. As the consumption story returns over the next six months, we expect demand to return and exceed the growth trajectory of previous years. The numbers are positive for most of the economies in the region – and as shown by our analytics, our platform increasingly reaches and influences these.

For responsible and sustainable packaging, with its attendant regulations and compliances, there is significant headroom to grow in India and the region. Our coverage includes the entire packaging supply chain – from concept to shelf and to waste collection, sorting, and recycling.

We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers. This is a large and complex canvas – the only thing that can work is your agile thinking and innovation together with our continuous learning and persistence.

The coming year looks to be an up year in this region, and this is the right time to plan your participation and marketing communication – in our rich and highly targeted business platform with human resources on the ground.
