Maintaining packaging integrity has never been more critical with the rise of sustainable packaging trends, particularly the increased adoption of rPET plastic in the food and beverage industry.
This blog provides comprehensive insights into sustainable packaging in the food and beverage industry. We define sustainable packaging, explore the rising popularity of rPET, and offer guidance on how a reliable leak testing solution can ensure every rPET product you manufacture is defect-free.
What Is Sustainable Packaging?
Sustainable packaging, also referred to as green or eco-friendly packaging, involves using materials and techniques in packaging creation that aim to minimize harm to the environment and conserve resources. This includes using more renewable or recycled materials, decreasing energy usage and emissions in manufacturing processes, designing packaging to reduce material consumption and waste production, and ensuring packaging is recyclable, compostable, or biodegradable once it's no longer needed.
The food and beverage industry is consumer-driven, and the growing customer demand for eco-friendly and sustainable products is motivating brand owners to explore sustainable packaging programs and options. Over recent years, there has also been an increase in government regulation requiring brand owners to use a certain percentage of sustainable packaging in their products.
Sustainable Packaging and PET/rPET Plastic in the Food and Beverage Industry
According to the International Bottled Water Association, people in the U.S. throw away more than 60 million plastic water bottles daily, most of which end up in landfills or as litter in America’s streets, parks and waterways. Fortunately, 78.8% of these plastic water bottles are made from PET, which is 100% recyclable when disposed of properly. When PET is recycled and reused, it’s known as recycled PET (rPET).
In recent years, some of the world’s largest water bottle brand owners have been able to incorporate rPET plastic into their packaging. For example, the use of rPET in bottled water packaging increased by 17.5 percent to 21 percent between 2008 and 2014, with many water bottle companies using 50, 75, and even 100 percent rPET.
Water bottles are not the only products being made from rPET. Numerous food and beverage brands are using rPET for their bottle and container packaging. This includes peanut butter containers, salad dressing bottles, jars for pasta sauce, bottles for fruit juices, and more.
PCR vs rPET: Understanding the Difference
The terms (Post-Consumer Recycled) PCR and rPET are often used interchangeably, although it’s important to know that PCR resin is an umbrella term that encompasses all forms of recycled plastic, including PET, PP (polypropylene plastic), and HDPE (high-density polyethylene). rPET plastic is a type of PCR material that specifically refers to recycled PET, which is most often used in bottles and containers in the food and beverage industry.

Benefits of rPET Sustainable Packaging
The following are the benefits of using rPET plastic in food and beverage packaging:
- Environmental Impact: PET and rPET products are 100% recyclable, and using more rPET reduces the food and beverage industry's carbon footprint by conserving resources, minimizing pollution, and decreasing waste sent to landfills or oceans.
- Consumer Preference: With growing environmental awareness, consumers are increasingly choosing products packaged in environmentally friendly materials, leading to higher demand for sustainable packaging options.
- Consumer Safety: rPET is a non-toxic material that does not react with food. The recycled material effectively preserves and protects the contents held within the bottles or containers, making it the ideal sustainable option for food and beverage packaging.
- Brand Image and Green Marketing: Companies that adopt sustainable packaging practices enhance their brand image and reputation by demonstrating a commitment to environmental stewardship, which can attract environmentally conscious consumers and investors.
- Regulatory Compliance: Governments worldwide are implementing stricter regulations on packaging waste and environmental impact, incentivizing companies to adopt sustainable packaging to comply with these regulations, including using a certain percentage of rPET in each container or bottle.

Future Trends in rPET Food & Beverage Packaging: Is It Here To Stay?
Brands across the food and beverage industry are embracing rPET packaging to reduce their environmental footprint and meet consumer demand for sustainable packaging products. Some examples include The Coca‑Cola Company, PepsiCo, and The Kraft Heinz Company.
However, implementing rPET plastic comes with its challenges, including:
- Contamination Risk: Ensuring the purity and safety of rPET can be challenging due to potential contamination from various sources, including residues from previous contents, labels, adhesives, and other impurities.
- Quality Control: Maintaining consistent quality standards for rPET packaging can be difficult due to variations in the quality and composition of recycled materials. Variability in rPET properties, such as color, clarity, and strength, may affect packaging performance and aesthetics.
- Supply Chain Constraints: Limited availability of post-consumer PET feedstock and competition with other industries for recycled materials can constrain the supply chain. The demand for rPET is currently outpacing supply, meaning securing a reliable and sufficient supply of high-quality rPET material may be challenging.
- Cost Considerations: While rPET offers environmental benefits, it may be more expensive than virgin PET plastic due to the costs associated with the collection, sorting, cleaning, and processing of recycled materials. Cost considerations may influence the affordability and feasibility of implementing rPET packaging, particularly for small and medium-sized businesses.
Despite these challenges, rPET plastic is expected to stay a topic of conversation in the food and beverage industry as more key industry players switch to 100% rPET plastic.
How fast the rPET trend catches on will depend on how much is invested in our recycling infrastructure, regulatory and government support for sustainable practices, and consumer education about its benefits. Addressing challenges such as contamination issues and ensuring consistent quality standards will also be crucial in cementing rPET's position as a sustainable packaging solution.
With the rise of sustainable packaging trends, leak testing will be more important than ever. Learn about the benefits of empty container leak testing in this blog post.
Importance of Leak Testing rPET Packaging
Ensuring the integrity of sustainable packaging, particularly those made from rPET, is important in maintaining product quality and safety. Every time a PET plastic bottle or container is recycled, cleaned, and processed, you run the risk of foreign material getting into the finished rPET product. This contamination may result in defects, such as pinholes and leaks, during the blow molding process.
Leaking food or beverage containers could lead to a reduced shelf life, bacteria overgrowth, spoiled products, and product recalls. Worst of all, defective packaging could damage the brand owner’s reputation and threaten the safety of the end-user customer.
Implementing a reliable leak detection machine into your production line is the only way to guarantee that every rPET container that reaches your customer is defect-free and meets your quality standards. Leak testing should be a priority in your production process to ensure the food inside the packaging remains fresh, safe, and free from contamination — ultimately keeping the end-user and customer safe.
