Why Multilayer Packaging Cannot Be Recycled and What Brands Should Do About It

Multilayer flexible packaging accounts for roughly 30% of all food packaging by volume in India (FICCI-EY India Packaging Report, 2025). It is also, for all practical purposes, unrecyclable. Not because recycling technology does not exist, but because the economics of separating bonded material layers make recycling commercially unviable at the scale of collection and processing infrastructure that exists today.

This matters in 2026 because the EPR for Packaging Rules (effective April 2026) require brand owners to take responsibility for the end-of-life of their packaging. For recyclable materials, that means proving the packaging was collected and recycled. For non-recyclable materials, it means paying penalty rates or finding alternative disposal routes. Multilayer packaging falls into the non-recyclable category for most practical purposes, which puts brands using it in the most expensive EPR compliance bracket.

Understanding why recycling fails for these materials, and what the alternatives are, is the starting point for brands trying to get ahead of the compliance curve.

Key takeaways

• Multilayer packaging combines PET, aluminium, PE, BOPP, and other materials bonded with adhesives. These layers cannot be mechanically separated for recycling at commercial scale.
• Only 9% of all plastic ever produced has been recycled globally (OECD Global Plastics Outlook, 2022). Multilayer structures are at the bottom of the recyclability hierarchy.
• India’s recycling infrastructure is designed for single-material streams: PET bottles, HDPE containers, aluminium cans. Multilayer films contaminate these streams, reducing the quality and value of the recycled output.
• EPR for Packaging Rules (April 2026) create a cost penalty for non-recyclable packaging. Compostable alternatives certified under IS 17088 avoid this penalty by entering organic waste streams.
• Mono-material structures and compostable alternatives are the two viable paths for brands that need to move away from multilayer packaging.

What multilayer packaging is and why it exists

A typical multilayer flexible packaging structure for food might be: PET (outer print layer) / adhesive / aluminium foil (barrier layer) / adhesive / PE (seal layer). Each material contributes a specific function. PET provides rigidity and printability. Aluminium provides oxygen and moisture barrier. PE provides heat sealability.

The combination works brilliantly for food protection. A single material cannot match the barrier performance that the multilayer structure delivers. This is why multilayer packaging dominates applications where shelf life and product integrity are critical: chips, biscuits, coffee, instant noodles, and most packaged snacks.

The problem is entirely at end-of-life. The adhesive bonds that hold the layers together during use are the same bonds that prevent separation during recycling. Mechanical recycling requires clean, single-material inputs. A PET recycler needs PET, not PET bonded to aluminium and PE. When multilayer films enter a recycling stream, they contaminate the output, reducing its quality and commercial value.

Why recycling does not work for multilayer films

The separation problem

The layers in multilayer packaging are bonded at the molecular level using adhesive lamination or extrusion coating. Separating them requires either:

• Chemical delamination — dissolving the adhesive with solvents. This works in laboratory settings but is not commercially viable at the scale needed. The solvent cost, energy input, and chemical waste generated exceed the value of the recovered materials.
• Pyrolysis — breaking the materials down through high-temperature processing in the absence of oxygen. This converts the packaging into fuel oil or syngas, not back into packaging materials. It is waste-to-energy, not recycling in the material recovery sense.
• Mechanical recycling with mixed output — grinding the multilayer film and processing it as a blended material. The output is low-grade composite that can be used for park benches, fence posts, and similar applications, but not for food packaging. This is downcycling, not closed-loop recycling.

None of these approaches produce food-grade packaging material from multilayer waste. The multilayer structure that made the packaging effective for food protection makes it permanently unfit for food packaging recycling.

The contamination problem

India’s waste collection system sorts packaging by material type. PET bottles go to PET recyclers. HDPE containers go to HDPE recyclers. When multilayer flexible packaging enters these streams, it contaminates the single-material input, reducing the quality and price of the recycled output.

Waste pickers, who handle roughly 90% of India’s informal waste collection, typically reject multilayer films because there is no buyer for them. The films have negligible resale value in the waste market. They end up in landfill or open dumps.

The economic problem

Recycling works when the recovered material has commercial value that exceeds the cost of collection and processing. For PET bottles, this is true: the recovered PET sells for INR 40 to 60 per kg. For multilayer films, the recovered material (if separation is even attempted) has minimal commercial value because it is a mixed, low-grade composite.

The result: no rational waste processor invests in multilayer film recycling because the output does not pay for the input. The technology exists; the economics do not.

What EPR means for brands using multilayer packaging

The EPR for Packaging Rules (effective April 2026) require brand owners, importers, and e-commerce entities to manage the end-of-life of their packaging. The obligation includes:

• CPCB portal registration
• Declaration of packaging quantities by material type
• Meeting recycling or composting targets
• Half-yearly and annual compliance returns

For recyclable packaging (PET, HDPE, aluminium), brands can demonstrate compliance by proving that the equivalent quantity of material was collected and recycled. For non-recyclable packaging, including multilayer flexible films, this path is blocked. The brand must either:

1. Pay the penalty rate for non-compliance with recycling targets
2. Invest in alternative disposal routes (pyrolysis, waste-to-energy) that are accepted by CPCB
3. Switch to packaging materials that are either recyclable (mono-material) or compostable (IS 17088 certified)

Option 3 is the only one that addresses the underlying problem rather than paying to work around it.

The two alternatives: mono-material and compostable

Mono-material structures

Mono-material packaging uses a single polymer type (typically PE or PP) for all layers. Because there is only one material, mechanical recycling works: the film can be collected, cleaned, melted, and reprocessed into new film or pellets.

The trade-off is barrier performance. A mono-PE structure cannot match the oxygen barrier of a PET/aluminium/PE laminate. For some applications (frozen foods, some bakery items), mono-material structures provide adequate barrier. For high-barrier applications (chips, coffee, protein powders), they do not.

Mono-material structures also require changes to recycling collection. Most Indian recycling systems are not currently equipped to collect and process flexible film at scale. The collection infrastructure exists for rigid containers (bottles, jars) but not for flexible pouches.

Compostable structures

Compostable flexible packaging uses paper-based or bio-polymer structures that decompose under composting conditions. Current generation metallised compostable papers achieve MVTR below 2 g/m2/day and OTR below 10 cc/m2/day, which is adequate for tea, coffee, confectionery, bars, dry snacks, and spices with 6 to 9 month shelf life.

The end-of-life advantage is that composting infrastructure for organic waste is developing faster than flexible film recycling infrastructure. Compostable packaging enters the organic waste stream alongside food waste, which means it benefits from the composting infrastructure being built under the Solid Waste Management Rules.

IS 17088 certification qualifies compostable packaging for the simplest EPR compliance pathway: the packaging composts as part of organic waste management, and the brand’s EPR obligation is fulfilled through composting rather than recycling.

The trade-off is barrier performance: compostable films do not yet match conventional multilayer structures for high-barrier, long shelf-life applications. For products needing 12+ month shelf life with sub-1 MVTR and OTR, multilayer or mono-material conventional films remain necessary.

Decision framework for brands

The “review annually” note on high-barrier applications reflects the pace of compostable material development. The barrier gap between compostable and conventional films is narrowing. Applications that require conventional multilayer today may be viable in compostable within 2 to 3 years.

Frequently asked questions

Can multilayer packaging be recycled at all?
In theory, yes, through chemical delamination or pyrolysis. In practice, no, at commercial scale. The economics of separating bonded layers do not work. Pyrolysis converts the material to fuel, not back to packaging. Mechanical recycling produces low-grade composite, not food-grade material.

What percentage of flexible packaging is actually recycled in India?
Rigid plastic packaging (PET bottles, HDPE containers) has recycling rates of 30 to 40%. Flexible multilayer packaging has near-zero recycling rates because it cannot be processed by existing recycling infrastructure and has negligible resale value in the waste market.

How do EPR rules affect brands using multilayer packaging?
Brands must declare packaging quantities and meet recycling or composting targets. For non-recyclable multilayer packaging, the recycling path is blocked, leaving brands to pay penalty rates or invest in alternative disposal routes. Switching to compostable or mono-material packaging simplifies EPR compliance.

Is mono-material packaging a good alternative to multilayer?
For applications with moderate barrier requirements, yes. Mono-PE or mono-PP structures can be mechanically recycled. For high-barrier applications, mono-material structures do not match multilayer performance. The suitability depends on the product’s barrier requirements.

What is the cost difference between multilayer and compostable packaging?
Compostable alternatives carry a 15 to 40% material cost premium. The gap narrows when you include EPR compliance costs for multilayer packaging (which faces the highest compliance burden under the new rules).

When will compostable packaging match multilayer on barrier performance?
Current compostable films work for 6 to 9 month shelf life applications. The barrier gap for 12+ month applications is narrowing but has not closed. Incremental improvements in metallisation and coating technology suggest that many current multilayer applications will have viable compostable alternatives within 3 to 5 years.
