Packaging sustainability: From ambition to execution

Packaging sustainability is moving from corporate targets to engineering, compliance and operational delivery.

For years, brands and packaging companies set ambitious goals to reduce virgin plastic, increase recycled content and make packaging recyclable or reusable.

Those ambitions remain, but the test is changing. A packaging format now has to do more than appear environmentally preferable. It has to meet regulatory requirements, make economic sense, work on production lines and perform in real recycling or reuse systems.

Sustainability is therefore becoming less of a standalone corporate initiative and more of a performance specification spanning material selection, manufacturing, compliance, procurement and end-of-life infrastructure.

How PPWR is changing sustainable packaging

Regulation is one of the clearest forces accelerating this transition.

The EU’s Packaging and Packaging Waste Regulation (PPWR) entered into force in February 2025 and began applying on 12 August 2026. It establishes common requirements for packaging and packaging waste across the EU, replacing the previous Packaging and Packaging Waste Directive.

The regulation introduces requirements covering the design, composition and recyclability of packaging. From 2030, packaging placed on the EU market will have to meet recyclability requirements, with further provisions progressively raising the performance threshold.

Material specifications are also becoming more important. From 12 August 2026, food-contact packaging containing PFAS at or above specified limits cannot be placed on the EU market.

The PPWR also sets a combined limit of 100mg/kg for lead, cadmium, mercury and hexavalent chromium in packaging and packaging components.

For packaging manufacturers and brand owners, the implication goes beyond compliance. Regulatory requirements increasingly have to be considered at the beginning of product development rather than checked at the end.

Films, coatings, inks, adhesives, labels and closures can all affect the performance and compliance of the finished pack. Compliance is therefore becoming part of packaging engineering itself.

Why EPR is changing packaging economics

Extended producer responsibility (EPR) is reinforcing the same shift through cost.

Under EPR systems, producers take greater responsibility for the costs associated with managing packaging waste. This creates a more direct financial connection between packaging design and what happens to a pack after use.

The UK’s packaging EPR scheme illustrates the direction of travel. From the 2026–27 financial year, household packaging waste disposal fees are being modulated according to recyclability.

Packaging assessed as red, or less recyclable, attracts a higher charge, while green-rated packaging receives a lower fee within the modulation system.

For red-rated packaging, the modulation factor rises from 1.2 in 2026–27 to 1.6 in 2027–28 and 2.0 in 2028–29.

That changes the commercial calculation behind packaging design.

A difficult-to-recycle structure can create environmental and regulatory problems while also increasing producer costs. Reducing unnecessary material, simplifying a structure or improving recyclability can therefore have financial as well as sustainability benefits.

Packaging engineers are consequently making decisions that can affect the P&L. Procurement, finance, compliance and packaging development have a shared interest in material weight, format complexity and recyclability.

The challenge becomes more complicated for companies operating across multiple markets. EPR schemes can use different recyclability definitions, reporting requirements, fees and collection systems.

A pack designed to perform well under one system may not necessarily achieve the same result in another, making early consideration of market requirements increasingly important for packaging development teams.

Why recyclability claims need evidence

As regulation becomes more specific, sustainable packaging is also moving from claims towards evidence.

Describing a package as recyclable based largely on its material composition is no longer enough in many markets. Companies need to understand whether the complete packaging format can move through the collection, sorting and recycling systems available where it is sold.

That creates a substantial data requirement.

Packaging companies need better information about the materials and components in a pack, how they interact and what happens after disposal. The Sustainable Packaging Coalition has highlighted the need to close data gaps and develop more consistent approaches to recyclability assessment, including better information on recycling rates by material and packaging format.

California’s SB 343 illustrates the direction of travel. The law restricts the use of the chasing-arrows symbol and other recyclability indicators unless specified criteria are met. CalRecycle’s assessment considers whether materials are actually collected and processed for recycling in California.

However, the measure is subject to ongoing litigation. A federal court issued a preliminary injunction in July 2026 blocking enforcement, making it important to distinguish the underlying policy direction from the law’s current enforcement position.

The broader lesson is more durable: environmental claims increasingly need to reflect real-world recovery systems rather than theoretical material properties.

That requires closer collaboration between packaging designers, material suppliers, converters, recyclers, compliance teams and brand owners. Data about packaging is becoming almost as important as the physical material itself.

Designing packaging for real recycling systems

Better evidence also changes the way packaging has to be designed.

The PPWR’s approach to recyclability goes beyond whether a material can technically be recycled under ideal conditions.

The regulation establishes requirements linked to the ability of packaging to be collected, sorted and recycled, as well as the quality of the resulting secondary raw material.

That puts the focus on the complete packaging structure.

A change to a film, coating, adhesive, label or closure can alter the recyclability of the finished pack. The same principle applies to fibre-based packaging.

Replacing plastic with paper does not automatically deliver a better environmental outcome if coatings or other components interfere with effective recycling.

Material substitution alone is therefore becoming a less reliable sustainability strategy. Packaging increasingly has to be assessed as a system.

In some applications, the most effective intervention may be lightweighting or rightsizing rather than replacing the underlying material. Elsewhere, it may mean simplifying a multilayer structure, eliminating unnecessary components or moving towards a mono-material format.

The objective is not simply to select a material that looks more sustainable. It is to protect the product with as little unnecessary material as possible while ensuring the resulting pack can function within its intended recovery system.

Taking sustainable packaging from pilot to production

There is another test that no sustainability target can bypass: the production line.

A promising packaging concept still has to be manufactured reliably at commercial scale. It needs to deliver the required barrier properties, shelf life, strength, sealing performance and appearance while running efficiently on industrial equipment.

Scalability is therefore becoming part of the definition of sustainable packaging.

Research and development is moving closer to manufacturing as companies seek to adapt recyclable materials and new barrier technologies to established processing environments.

This is particularly important for formats where a change in material or structure can affect machinery performance, filling speeds or product protection.

For packaging manufacturers, converters and brand owners, that creates a more demanding definition of innovation.

A sustainable packaging project has to answer practical questions. Can the format run at the required speed? Does it protect the product adequately? Can it maintain shelf life? Will existing machinery process it reliably? Is sufficient material available at the required quality and volume? What happens to waste generated during production? And will the finished package meet recycling requirements in its target markets?

These are not secondary implementation details. They can determine whether an innovation becomes a commercial packaging format or remains a pilot.

A concept that reduces packaging material but causes higher product losses, unreliable production or unacceptable shelf-life performance may simply transfer environmental and economic impacts elsewhere.

Successful sustainable packaging therefore has to work as both an environmental intervention and an industrial product.

Why reusable packaging depends on infrastructure

The same emphasis on execution is reshaping reusable packaging.

Reuse has long featured prominently in circular economy strategies. The difficult part is not designing a container that can be used again, but building the system that allows repeated use at scale.

That requires collection, return, washing, redistribution, tracking and, in many cases, standardisation.

The PPWR is pushing these questions further into commercial planning. From 2030, certain economic operators using transport packaging will have to meet reuse targets, while other requirements cover different packaging categories and business models.

Reuse is therefore a systems question rather than simply a packaging-format question.

A durable reusable container achieves little if it is rarely returned. Environmental and commercial performance can depend on transport distances, return rates, washing operations, container durability and the number of cycles achieved.

Real-world programmes are important because they generate evidence about those variables. In the Netherlands, a nationwide shared reusable-packaging system reported more than 169 reusable products on supermarket shelves one year after its June 2025 launch, while monthly sales of reusable products had grown 13-fold.

Such programmes test something that packaging design alone cannot establish: whether a reuse system can work effectively for consumers, retailers, manufacturers and logistics providers at the same time.

Execution becomes the measure of sustainable packaging

Packaging sustainability is becoming less about selecting a supposedly sustainable material and more about designing a system that works.

The strongest formats will need to satisfy several requirements simultaneously. They must protect the product, run efficiently through manufacturing and distribution, comply with changing regulation, withstand scrutiny over environmental claims and function within the recycling or reuse infrastructure available in their target markets.

For packaging companies and brand owners, this moves sustainability out of the realm of standalone commitments and into mainstream product development.

The industry’s ambitions have not disappeared. But the measure of progress is increasingly not what a company intends its packaging to achieve, but what that packaging can demonstrably deliver at scale.
