Active packaging technologies are the best preventive measures to reduce food waste. But many of these never reach the common public. The communication director at AIPIA, Andrew Manly, gives his opinions about innovations in this field. And, it is said that there is a global 30% food wastage as it never gets eaten.

Food wastage in several places is due to different reasons. In Europe and North America, food wastage happens in the warehouse and logistics part, at the retailer end. Many active packaging methods are available to limit bacterial growth, delay ripening or take the oxygen out of the pack, and increase the life of proteins and new production. If these solutions have been used in the markets, we are yet to see their influence in daily life.

There is plenty of work involved in the development of active or Flexi packaging to limit the growth of microbial or bacterial growth. The AIPIA newsletter has been published regularly with reports on the various research and development activities at the technical universities that are giving results.

Solutions to control food wastage

Companies are trying to maintain their focus on nanotechnology with the fibers obtained from the durian fruit skins to produce a natural compostable, edible, and biodegradable material. However, they are not used at large by people.

These products are not commercially viable, which can be seen in the results of AIPIA’s involvement with the NanoPack project. This three-year project produced an antimicrobial film from essential oils like oregano and a few halloysite nanotubes. The initial film limited the mold growth in bread within three weeks, increased the sales of fresh cherries by 13%, and expanded the shell life of yellow cheese by more than four days.

Other options for active food packaging

The antimicrobial film requires approval from the European Food Standards Agency (EFSA), and since this process takes a long time, such solutions get lost. Currently, there are few established inhibitors in the market, like silver. Silver nitrate is an antimicrobial agent, but the metal used in food packaging makes it hard to recycle. Thankfully, there’s an alternative – graphene.

Graphene has good antimicrobial properties and can be reused but is expensive, like silver. There are more environment-friendly and less costly options available for active food packaging. They are methods like nitrogen removed from products to keep them clean and usable for a long time. Such methods are being widely used as they are cost-effective.

Customers’ opinions about alternate packaging solutions

Now, the question is – Are the eco-friendly options being used by the food producers in packaging? Consumers do not like any external additions to their food, but with NanoPack, which would save food and protect them from harmful materials, they were okay with it.

Food wastage costs more water, energy, and the fuel used in transport, and producing food packaging to reduce the amount of food is better for the future.

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!
