Last year, Packaging South Asia reported that ALOK made the first biodegradable film in India in collaboration with US-based Willow Ridge Plastics. Another project with Willow Ridge entailed a technology for producing recycling multi-layer films. The ready-to-use drop in biodegradable film product is closer to commercialization and is already in the beta testing phase in the US.

“Frankly speaking, we are still coming out of a lazy Diwali plus Christmas break and things are still in the process of catching pace. For a start, we have set up a full-fledged chromatography lab. With this one can go down to the lowest ppm level of elemental identification and analysis,” says Vikram Bhadauria, director of ALOK Masterbatches.

ALOK’s new chromatography lab

The chromatography lab at ALOK’s ATIC in Okhla will help in discovering toxins and trace metal chemicals. The company already had the XRF equipment for detecting the presence of heavy metals. Heavy metal is one part of the spectrum that makes up toxins and carcinogens. There are many other chemicals including dioxins and other pesticides that are capable of contaminating food and other products. With the new chromatography lab, the company now has the entire broad spectrum capacity to detect these unwanted chemicals which was not possible with the earlier XRF machine. Chromatography helps identify not only unknown chemicals, which may be good or bad for human consumption, but also a lot of bad chemicals that may go into a product accidentally if not intentionally. With the new testing capabilities, any form of food packaging or food product can be scanned for the presence of toxins or pesticides in it.

“Physical infrastructure-wise this is what we have recently added, while on the application front we are still concentrating on biodegradability and recyclability. Even with two states banning plastics, I still feel the ban is a knee-jerk reaction as I had said in our earlier interaction as well. At the end of the day, plastics will remain the most sustainable choice for a country like India where the population is looking for affordable solutions. One cannot force the entire population to use exotic materials such as wood or paper. They’re good in urban environments but for rural and semi-rural areas to begin consuming these products is not feasible.

“For instance, right now if one thinks of plastic, it is only to think about the plastic bag or a plastic straw. The poor straw has probably less than 5% of pollutants capable of harming the environment but it has received the maximum flak. This clearly shows that we have some misguided priorities. These bans will come and it is the people’s consumption behavior that pressurizes government bodies to enforce these bans,” Bhadauria explains.

Re-new, Re-nex and Re-bond

ALOK is working on several new projects for recycling plastics, which cannot as yet be discussed meaningfully. At the same time it has developed three products for recycling plastics that are now being commercialized widely. These products are Re-new, Re-nex and Re-bond. Re-new is to increase the recycling properties of any recyclable material; Re-bond increases the strength of the recycled material because typically the recycled product faces loss in mechanical properties; and the rebond product is used to upcycle the recycled plastic product.

Another issue with recycling is the odor of the material. AMB has come up with a new product called Re-nex to eliminate the pungent odor that sometimes emanates from recycled products. Re-nex uses a pleasant fragrance to mask the unpleasant odor or a chemical neutralizer which can neutralize the odor with the addition of some chemicals.

The impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.
