Polymer giants unveil mono-material pivots to meet EPR mandates at Respack

The session, chaired by Unmesh Nayak, president (olefins and derivatives) at Reliance Industries, established how the global polymer industry is executing interventions across the three pillars of the circular economy: reduce, reuse, and recycle.

Nayak framed the discussion by acknowledging that while the industry faces intense competition from alternative materials like glass and metal, plastics remain the most critical medium for primary and secondary packaging execution. He noted that over the past seven to eight years, raw material producers have pivoted toward constructing advanced circular solutions designed to lower material densities, replace complex multi-material structures, and optimise the post-consumer recycling stream.

Indigenous metallocene advancements and chemical recycling
Vineet Gupta, head of technical marketing at HPCL-Mittal Energy, asserted that the sustainable packaging narrative must transcend material-versus-material competition and focus on responsible design and consumption. To facilitate consumer brands’ shift toward mono-material polyolefin laminates, HMEL is rolling out its next-generation PolySure metallocene and machine direction orientation (MDO) resin technologies. By stretching PE films in a single direction via MDO processing, converters can amplify structural strength, dart-impact resistance, and optical clarity while down-gauging film thickness.

Gupta also highlighted the commercial viability of polyolefin elastomers (POE), — synthesised using advanced single-site catalysts — which fuse the elastic flexibility of rubber with the high-speed thermal processability of plastics to optimise form-fill-seal (FFS) lines. 

In the rigid space, Gupta demonstrated structural weight transitions, pointing out that shifting from conventional 20-kg metal drums to advanced, high-environmental stress crack resistance (ESCR) bimodal HDPE chemical drums yields an 8-kg weight reduction and a 40% carbon footprint compression.

Addressing recycling limits, he observed that while India generates roughly 9-million metric tons of plastic waste annually, recycling is heavily skewed toward rigid containers, leaving flexible structures largely underserved. He emphasised that while mechanical recycling faces inevitable polymer degradation due to molecular weight distribution shifts after repeated heat cycles, chemical recycling represents the definitive future.

HMEL, alongside RIL, has scaled commercial circular polymers derived from pyrolysis oil, certified via International Sustainability and Carbon Certification (ISCC PLUS) frameworks with full blockchain traceability. “Mechanical recycling and chemical recycling will co-exist,” Gupta stated, confirming that the technology to deploy food-grade, circular metallocene films is fully operational in India.

Fully formulated polypropylene mono-materials
Vaibhav Kumbhar, technical manager – application development and technical support, Basell Polyolefins India, provided technical matrices for replacing traditional, unrecyclable PET/PE or multi-material foil structures with fully formulated, recyclable polypropylene mono-material laminates. 

To achieve the high stiffness, optical brilliance, and heat resistance required to eliminate PET, LyondellBasell has introduced its Adsyl high-crystalline polyolefin portfolio, allowing for the construction of high-barrier BOPP/CPP structures.

To overcome the sealing bottlenecks of mono-PP lines, the company leverages its proprietary Catalloy catalytic polymerisation technology to produce ultra-low seal initiation temperature (SIT) resins, driving down functional sealing windows to 80°C for BOPP skin layers and 85°C for CPP configurations without compromising seal integrity or hot-tack strength.

Under its global Circulen brand umbrella, LyondellBasell has institutionalised three distinct circular pathways: CirculenRecover, CirculenRevive, and CirculenRenew. Life cycle assessments (LCA) conducted by LyondellBasell confirm that their bio-circular CirculenRenew platform delivers a cradle-to-gate carbon footprint reduction, generating negative global warming potential (GWP) values up to -1.68-kg carbon dioxide per kg of polypropylene produced.

Bimodal resin architectures
Satya Bhushan, senior manager – sales and commercial management (packaging), ISC, Borouge, contextualised the company’s unified market strength by leveraging the joint manufacturing and R&D capacities of ADNOC, Borealis, and Nova Chemicals. 

Bhushan emphasised that sustainable packaging must actively protect the future through precision material down-gauging and rigorous design for recyclability (DfR) compliance. To solve the physical inconsistencies and aesthetic deficiencies inherent to post-consumer recycled plastic, Borouge leveraged its proprietary Borstar bimodal multi-reactor technology. 

Unlike unimodal single-reactor polymers, bimodal PE and PP architectures allow for a broad molecular weight distribution. This unique molecular engineering delivers resin processability alongside vastly superior mechanical toughness, allowing structural film walls to accept higher concentrations of recycled PCR content without tearing or splitting on converting lines.

In compliance with the Central Pollution Control Board (CPCB) and extended producer responsibility (EPR) mandates in India (which enforce strict minimum PCR blending percentages), Borouge highlighted its global mechanical recycling brand, Recleo. At PlastIndia 2026, Borouge announced a co-branding agreement with Pashupati Group. Under this partnership, Pashupati’s high-purity PCR grades are blended with Borouge’s functional bimodal booster resins, delivering uniform processability and holding force for industrial collation shrink films and retail applications. 

Bhushan also highlighted successful commercial trials utilising up to 50% PCR content for heavy-duty consumer paint pails and large-scale collation shrink wrap for PepsiCo and Varun Beverages.
