Paperization and sustainable packaging options were meaningfully discussed by the panel “From Concept to Shelf, to Recycling to Recyclates in the Design of Packaging,” at the maiden PACK.Nxt conference at Mumbai on 18 January 2024. The session was excellently moderated by plastic recycler Banyan Nation’s chief business officer, Rashi Agrawal.

PN Shridharr, general manager, of sustainable products and packaging, ITC, gave the example of the one-kilogram pack of Aashirvaad Atta for demonstrating the switch from plastic to paper packaging. “Paperization seems to be the trend globally. The key aspect of this switch from plastic to paper was enhancing the barrier properties of paper, which is a very porous material and cannot easily match the properties offered by plastic. What we did was reduce the overall amount of plastic in the packaging of the 1 kilogram pack of Aashirvaad Organic Atta to 40% by switching from a 100% plastic laminate to a mix of paper and plastic laminate.”

The biggest challenge that ITC had to overcome was to work on the way of handling the package and conduct a number of drop tests to ensure that it met the product handling and logistics requirements. “We also had a lot of support from our topmost management in meeting this goal,” he said adding, “ITC is trying to move secondary packaging from plastic to paper as it doesn’t require the same level of barrier properties. For Sunfeast biscuit packs, we have moved the secondary packaging to kraft paper packs.”

“Too Yum Foods has a gamut of product lines, where certain products are from our own brand and other brands are retailed as a part of Spencer’s Retail and Nature’s Basket,” said Subhra Sankha Nandi, head – packaging commercialization of Too Yum Foods which is a part of the RP-Sanjiv Goenka Group. The easiest way to contribute to the environment without changing much is to shift from plastic to paper packaging. “We have started targeting this with Karare (a type of baked snack) and potato chips in our product line and it will be gradually implemented across most of our products,” he said. “Our multigrain chips have four sharp edges – if we drastically reduce the thickness of plastic these sharp edges may end up opening the packs,” he added.

The company has made many changes in its secondary packaging, Nandi said, adding that these initiatives have helped in reducing the overall cost as well as overall consumption of paper. “For primary packaging, we have worked from the protection point of view while on secondary packaging we have worked on reducing paper consumption. We are under discussion with our partners to develop packaging from a sustainability point of view while keeping in mind the affordability and ease of availability of alternate materials,” he shared.

Lifecycle analysis helps define the scope and the boundaries of packaging, Shridharr said, adding that the overall global consumer conception that paper packaging is more environmentally friendly is driving the switch from plastic to paper packaging. “The recyclability of both paper and plastic packaging depends a lot on segregation at source. The key differentiator is that when you look at paper packaging, its raw material is naturally occurring, grown on farmlands and can be converted to farm manure,” he said.

“In addition, we have grown up seeing that paper is being collected and recycled,” he shared, adding that in the last 60-70 years, there has been a very well-settled value chain including the raddiwalas who collect newspaper and corrugated boxes from house to house. “A critical point of consideration while designing the packaging for products is to look at how to identify and send the packaging to the correct recycling stream,” he added.

Nandi suggested that we have to look at the recycling angle from all the verticals. Our prime focus while designing packaging solutions, as an industry, should be on cost-effectiveness and recyclability.

Shridharr informed the audience that ITC has a Life Sciences and Technology Centre in Bengaluru where one of the things that it is working on is monomaterial packaging. He quoted an international survey that reported that almost 42% of global packaging, including rigid and flexible packaging, is looking at paperization as an alternative.

The 2023 McKinsey Global Consumer Research on Consumer Perceptions shows that Indian consumers are willing to pay more if we communicate to them how sustainable the packaging is and what efforts the brand is making toward sustainable packaging options. Indian customers also opted for glass, paper and rigid packaging as the most sustainable packaging options, according to the report.

Shidharr also explained that the kind of paper that we use for paperboard packaging comes from growing specific kinds of trees and does not involve deforestation. There is no relation between the Indian paper industry and forests – “We have our own 20 million tons of paper production in India and every kilogram comes from farmers’ plantations, who use their non-food crop areas mainly for Eucalyptus and Casuarina,” he said.

“When we talk about paper versus plastic, we are looking at something sustainable that does not hamper our ecological balance,” Nandi said. “We are looking at plastic minimization, not at completely getting rid of plastic.”

“It is not going to be paper versus plastic, it will always be paper with plastic,” Shridharr concluded.

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. Share your thoughts and plans to inspire and mobilize our editorial and advertising teams!
