Sustainable Packaging Materials: A CPG Guide to Hidden Risks

What are the regulatory risks of new packaging materials?

The global regulatory landscape for packaging is fragmented and constantly changing. A package that is compliant in one market may be illegal in another. For example, the EU’s Packaging and Packaging Waste Regulation (PPWR), which reached political agreement in late 2024, sets ambitious targets for 2030. It mandates specific recycled content levels, such as 30% for most PET beverage bottles, and introduces new recyclability performance grades.

These rules differ greatly from regulations like California’s SB 54 or the UK’s Plastic Packaging Tax, which has its own recycled content thresholds. Brands must also track Extended Producer Responsibility (EPR) fee changes and labeling rules across many jurisdictions. Using spreadsheets for this is no longer enough. It exposes brands to fines, market access denial, and expensive last-minute redesigns.

How do material choices affect supply chain stability?

The supply chains for many sustainable materials are still developing, making them volatile. The price and availability of high-quality, food-grade recycled PET (rPET), for instance, can change quickly. These changes depend on local collection rates and global demand. For bio-based materials like PLA, sourcing is a major concern. Brands must ensure their suppliers do not contribute to deforestation, an issue scrutinized under regulations like the EU Deforestation Regulation (EUDR). A failure in supply chain due diligence can stop production and damage a brand’s reputation.

What is the risk of greenwashing?

Consumers and regulators are more skeptical of vague environmental claims. Terms like “eco-friendly” or “green” are now targets for legal action. The Empowering Consumers for the Green Transition Directive (ECGT) is now law in the EU and will ban generic green claims from September 2026. While the separate Green Claims Directive proposal was paused in June 2025, the ECGT and national rules like the UK’s Green Claims Code show a clear trend toward stricter enforcement. Promoting a compostable package without checking if customers have access to industrial composting facilities is a classic example of greenwashing. This exposes brands to penalties, including fines that can reach up to 4% of annual revenue under some proposed frameworks. Proactively monitoring the narratives from stakeholders like NGOs and industry groups is vital to avoid public backlash.

Recycled Plastics (rPET, rHDPE)

• Pros: Supports a circular economy by reducing reliance on virgin fossil fuels. Often has a lower carbon footprint than virgin plastic production.
• Cons: Supply and price can be highly volatile. Quality can degrade after multiple recycling cycles. Meeting strict food-contact safety standards can be a significant technical challenge.
• Hidden Risk: The source of your recycled material matters. Sourcing from regions with poor waste management practices or unclear chains of custody can inadvertently link your brand to negative environmental or social impacts, undermining your sustainability goals.

Bio-based and Compostable Plastics (PLA, PHA)

• Pros: Made from renewable feedstocks like corn starch or sugarcane. Can be designed for industrial composting at the end of life, reducing landfill waste.
• Cons: Can compete with land used for food crops. Most require specific industrial composting conditions to break down and will not biodegrade in a landfill or marine environment. Can contaminate traditional plastic recycling streams if not sorted correctly.
• Hidden Risk: The biggest risk is the gap between technical compostability and practical reality. If industrial composting facilities are not widely available to your customers, your “compostable” packaging effectively becomes single-use waste, opening you up to greenwashing claims.

Fiber-Based Materials (Paper, Cardboard)

• Pros: Derived from a renewable resource. Has one of the highest recycling rates globally. Widely accepted and understood by consumers.
• Cons: Sourcing can be linked to deforestation if not managed responsibly. Often requires plastic coatings or liners to provide a barrier for food products, which can make recycling difficult or impossible.
• Hidden Risk: Lack of supply chain transparency. Without credible certifications like the Forest Stewardship Council (FSC), you cannot guarantee your packaging isn’t contributing to illegal logging or deforestation, a major compliance risk.

Map Your Regulatory Exposure

Start by identifying all current and proposed packaging regulations in your key markets. This includes national and local rules on recycled content, labeling, EPR fees, and restricted substances. Go beyond final laws. Monitor policy drafts, committee discussions, and amendments to see changes before they become law.

Assess Supply Chain Resilience

For each potential material, analyze its supply chain. Evaluate the long-term availability, price stability, and quality of the raw material. For recycled materials, this means understanding the collection infrastructure in your regions. For bio-based materials, it requires deep due diligence on your suppliers’ agricultural practices.

Validate End-of-Life Viability

A material’s recyclability is theoretical until proven in practice. Confirm that the infrastructure to collect, sort, and reprocess your packaging exists and is accessible to most of your customers in a market. If it doesn’t, you risk contributing to waste and facing greenwashing accusations.

Monitor the External Narrative

The sustainability landscape is shaped by policymakers, activists, competitors, and the media. Use an intelligence system to track these narratives. Understanding which materials are gaining favor with regulators or being targeted by NGOs provides foresight to guide your strategy and avoid investing in a future liability.
