The Use of PCR Material in Food Contact Packaging

As the demand for sustainable packaging continues to grow, brands and manufacturers are looking for ways to reduce their carbon footprint and reliance on virgin plastics. One of the most effective strategies is incorporating post-consumer recycled (PCR) materials into packaging. PCR materials have many sustainability benefits, reducing plastic waste, supporting a circular economy, and helping brands meet evolving eco-friendly packaging regulations.

Though when it comes to food contact packaging, using PCR material presents unique challenges. Issues such as contamination risks, regulatory approvals, and material performance must be carefully managed to ensure both food safety compliance and sustainability. In this article, we’ll explore the different types of recycled content, the challenges of using PCR in food packaging, and the certifications required for food-safe recycled materials.

Types of Recycled Content in Packaging

Understanding the different types of recycled plastic is essential for choosing the right material for food-grade packaging. There are four key variations of recycled plastic in packaging;

• Post-Industrial Recycled (PIR) Plastic: PIR comes from manufacturing waste—offcuts, production defects, and excess plastic that never reaches consumers. Since it hasn’t been used, it is cleaner and easier to recycle into new packaging solutions.
• Post-Consumer Recycled (PCR) Plastic: PCR is made from plastic waste collected from consumers, such as used bottles, containers, and flexible films. This material undergoes an extensive recycling process to remove contaminants, making it a more complex but essential solution for reducing plastic waste in food packaging.
• Ocean-Bound PCR (OB-PCR) & Ocean Plastic: OB-PCR is sourced from coastal areas where plastic waste is at risk of entering the ocean, while ocean plastic comes from plastics already polluting marine environments. While these solutions help tackle plastic pollution, they are less commonly used in food packaging due to contamination concerns.

Plastic recycling: Mechanical vs. Chemical

There are two main adopted methods of plastic recycling - mechanical and chemical. Each has their pros and cons, and plays a significant role in the application of PCR in food contact packaging.

‍

Mechanical Recycling

The most common plastic recycling method, mechanical recycling involves washing, shredding, and reprocessing plastics into new materials. However, this method does not fully remove contaminants like inks, adhesives, and food residues, making it more challenging to use for food-contact applications unless strict food-grade recycling processes are followed.

‍

Chemical Recycling

A newer technology, chemical recycling breaks plastics down to their molecular level, removing impurities and producing high-quality recycled plastic that can be used in food-safe packaging. Although more expensive and less widely available, this method is expected to play a significant role in the future of sustainable packaging.

Challenges of Using PCR in Food Packaging

While PCR packaging is a viable alternative, it has historically come with several challenges. Contamination is a primary concern, as residual chemicals, inks, and adhesives from previously used plastics must be completely removed to meet food safety standards.

‍

Beyond contamination, PCR plastics can be harder to process due to their rough texture, making it challenging to achieve high-quality printing. Some recycled resins also tend to be weaker or more brittle than virgin plastic, which can impact packaging durability and machine efficiency. 

‍

However, despite these challenges, advancements in plastic recycling technologies are improving the usability and safety of food-grade PCR materials.

‍

Food Contact Certification for PCR Materials

Contrary to popular belief, PCR materials can be certified as food-safe. The most commonly approved material for food-contact use is PCR PET, which is widely used for beverage bottles and food containers. HDPE also has strong food-contact approval, particularly in rigid packaging. PP is gaining recognition, while LDPE and LLDPE are newer entrants in food-safe PCR packaging, with mechanical recycling now enabling food-grade approvals in some cases.

‍

To obtain food-contact certification, PCR materials must come from controlled recycling streams, undergo strict purification processes, and pass extensive food safety testing.

Why Brands Should Prioritize Food-Safe PCR Packaging

With global packaging regulations becoming stricter and consumer demand for sustainable products increasing, ensuring that food packaging is both eco-friendly and food-safe is crucial.

• Regulatory Compliance: Governments worldwide are introducing stricter packaging sustainability laws, requiring brands to use certified recycled materials and meet extended producer responsibility (EPR) requirements.
• Consumer Expectations: Shoppers are more aware than ever of sustainable packaging solutions. They expect brands to use food-safe PCR packaging that aligns with eco-friendly practices while ensuring product safety.
• Long-Term Sustainability Goals: Incorporating certified PCR materials into flexible packaging helps brands reduce their environmental footprint, comply with emerging regulations, and future-proof their packaging strategies.

Food Safety Certifications for PCR Packaging

To ensure compliance with food safety standards, brands should look for recycled packaging materials that meet the following certifications:

• FDA Compliance (USA): Governs materials used in direct food contact packaging.
• EFSA (European Food Safety Authority): Sets strict standards for food-safe recycled plastics in the EU.
• ISO (Food Safety Management): Ensures best practices in food packaging production.
• BRCGS (British Retail Consortium Global Standard): Regulates food-safe packaging suppliers.

How does food safety testing work? 

At a high level, certifying PCR packaging materials involves rigorous migration testing to ensure that no harmful substances transfer from the packaging to food. Purity screening checks for residual contaminants, while process control audits verify that the recycling and manufacturing processes meet food safety compliance standards.

What does PCR stand for?

PCR stands for Post-Consumer Recycled material or Post-Consumer Resin. These are recycled plastics referred to as rPET (Recycled Polyethylene Terephthalate), rPP (Recycled Polypropylene Plastic) and rHDPE (Recycled High-Density Polythene).

What is PCR plastic?

PCR plastic is made from recycled plastic that can be widely recycled and then reprocessed into a resin, used to create new packaging. Giving packaging a second life, this process reduces the amount of plastic waste.

How is PCR plastic made?

Plastic waste is collected and colour-absorbed, then shredded into fine granules. These are then melted down and reprocessed into new plastic.

What are the benefits of PCR plastic?

Many benefits come with using PCR plastic. This type of plastic is less wasteful than new plastic, as a reduced amount of waste is produced and collected, creating less waste in landfills and water sources. PCR plastic also reduces your carbon footprint for a more positive impact on our Earth.

Does PCR plastic have disadvantages/limits?

During each recycling process, the materials can begin to lose their substance/quality, which is why there are high-grade recyclates and low-grade recyclates. As well as this, not all PCR plastic can be recycled, depending on its use.

Can PCR plastic be recycled?

Yes, PCR plastic is recyclable depending on how it is used. At Susanne Kaufmann, all of our PCR packaging is 100% recyclable.

How many times can PCR plastic be recycled?

PCR plastic is a circular material, so it can be recycled after use. You can safely recycle PCR plastic approximately seven-to-nine times.

Is PCR plastic biodegradable?

No, PCR plastic is not biodegradable. Biodegradable packaging naturally breaks down into non-toxic component substances once consigned to a compost heap. PCR packaging has already achieved the goal of sustainability before the consumer even purchases it, with no need for further reprocessing.

What is the difference between PCR and other eco-friendly packaging?

There are many different eco-friendly packaging options out there, such as recyclable packaging and biodegradable packaging. When looking at recyclable or recycled plastic, recyclable plastic needs to be a 'one material plastic' and not a mixture of different plastics to be considered 100% recyclable. For example, if you have a refill packaging with a cap-closure and this cap is made from another plastic, it would not be considered 100% recyclable. For this reason, we created our unique capless design, reducing the number of plastic materials needed and ensuring the packaging is 100% recyclable. Additionally, our secondary packaging uses 100% recyclable paper.

Our 100% Recyclable Refill System

We recently launched our 100% recyclable refill bottles for our best-selling 250ml cleansing products: Purifying Cleansing Gel, Hair & Body Wash, Invigorating Hair & Body Wash, Hand Soap, Soothing Cleansing Milk and Soothing Toner.
