Pressure-Sensitive Labels:
A Packaging Circularity Enabler
Breakthroughs in PSL technology significantly improve recycled packaging’s quality and the efficiency of the recycling process.

The consumer packaged goods (CPG) industry is at a critical juncture as consumers, retailers and regulators put increasing pressure on brands to implement effective and transparent sustainability programs. These market and legislative demands present CPG brands with both challenges and opportunities across the supply chain. Proactive brands are recognizing that packaging innovation isn’t just an option, but a strategic imperative to unlock new opportunities and meet their sustainability goals.
The momentum toward circularity
A convergence of trends is fueling the drive toward a circular economy. Governments at national, regional and even local levels are setting ambitious new packaging goals, aiming to lower manufacturing emissions, increase recycling rates and reduce waste. In North America, for example, we’re seeing the introduction of mandated minimums for Post-Consumer Recyclate (PCR) content and Extended Producer Responsibility (EPR) legislation, pushing brands to take greater accountability for their packaging’s end-of-life.
Consumer demand is equally influential. Consumers perceive packaging as one of a brand’s most controllable and visible sustainability elements. In fact, approximately one-third of consumers consider sustainable packaging among the top three ways brands can address their environmental concerns.1 This translates into strong purchasing preferences for products and packaging that demonstrates commitment to sustainability. Consumers are backing up this preference with their wallets, with data showing a willingness to pay approximately 12% more for packaged goods with minimal environmental impact.2
Retailers are also leveraging their influence. They are actively urging suppliers to adopt more recyclable or compostable materials, reduce overall packaging and, in some cases, leverage reuse or refill solutions to reduce waste.
Despite this collective push, challenges exist, particularly when it comes to improving packaging recycling. While nearly all global CPG brands have a goal of 100% recyclable, reusable and compostable packaging by 20303, over 80% of brands are falling short of their waste and recycling targets.4 This reality points to the need for deeper, more systemic innovation, moving beyond surface-level adjustments to create transformational change.

Packaging as a catalyst for circularity
As brands move toward a more circular economy, packaging’s role as a sustainability component is expanding. It now serves as a signal of a brand’s sustainability ambitions based on format, design and material choices and a key vehicle for communicating with consumers about recycling and reuse. Packaging’s environmental footprint is substantial, with roughly 3.5 trillion packages produced each year to contain food, beverages and home and personal care products.5 For example, global plastic consumption has quadrupled over the past 30 years, accounting for 3.4% of global greenhouse gas emissions and 350 million tons of waste — 40% of which comes from packaging.6
However, recycling can make a significant difference. Recycled rigid plastics like PET and HDPE are over 70% less emissions-intensive than their virgin plastic counterparts.7 To put this into perspective, a modest 1% increase in recycling rates can reduce approximately 2,000 tons of plastic waste annually for a beverage company producing 10 billion bottles.8 This is just one example of the potential offered by incremental recycling improvements.
Every package element has a role to play in advancing circularity. For instance, recent innovations in pressure-sensitive labels (PSLs) are helping position the technology as packaging circularity enablers.
The case for pressure-sensitive labels
Breakthroughs in PSL technology significantly improve recycled packaging’s quality and the efficiency of the recycling process. One key innovation is clean release adhesives, which improve the quality of recycled rigid plastics and can be made durable to allow bottle reuse. These highly sustainable decoration solutions are recognized by the Association of Plastics Recyclers (APR), RecyClass and other bodies to be compatible with standard rigid plastic recycling streams, such as HDPE and PET.

Digitally enabled PSLs, including those embedded with RFID and QR codes, can also support the shift toward circular packaging.
- Supply chain transparency and efficiency: Digitally enabled labels provide supply chain transparency, enhance inventory tracking, improve sorting efficiency and reduce waste.
- Enhanced consumer engagement for returnables: QR codes printed on labels can yield higher bottle return rates by providing consumers with clear, real-time instructions on how and why to return bottles.
- Optimizing reuse systems: RFID-enabled labels allow brands to monitor where bottles dwell, optimize collection logistics and reduce the total number of bottles in circulation by up to 10% — cutting costs and minimizing environmental impact.9
The strategic direction for brands is clear: Sustainability will become a key performance criterion and value-driver for brands over the next decade. Most consumers are increasing their scrutiny on packaging, and brands with sustainable packaging will increasingly be able to make differentiated consumer claims. Brands that consumers perceive as circularity innovators will enjoy a competitive advantage over businesses that lack a sustainability-leader reputation.
The imperative for future-forward brands
The global push for sustainability and circularity is poised to fundamentally transform the packaging industry over the next five to 10 years. Forward-thinking brands will be instrumental in efforts to increase recycling and reuse, which will ultimately reduce carbon emissions and waste across the global economy. As brands seek to advance their recycling and reuse models, recent innovations in PSL technology can be an important contributor to circular packaging. While the stakes are high in this transition, the potential rewards are even greater for companies that successfully incorporate circularity into their packaging strategies.
