AD CleanFlake Technology from Avery Dennison Corp. looks unspectacular on a supermarket shelf, but you notice the difference when you crush a PET bottle and hear the label crackle instead of smearing. The whole construction is designed to let go in the recycling wash. That small moment in the kitchen bin is where the product quietly earns its keep.
How AD CleanFlake works
AD CleanFlake is a pressure-sensitive label technology built specifically for PET bottle and tray recycling, using an adhesive that releases cleanly in hot caustic wash. The label then floats while the PET flakes sink, keeping the recycled plastic clear for bottle-to-bottle reuse, according to Avery Dennison’s own product documentation. The concept sounds simple, but getting adhesive, ink and film to cooperate in industrial recycling plants is where the engineering starts.
The construction is typically made up of a printable film face, the CleanFlake adhesive that debonds in the wash, and a backing material compatible with standard labeling equipment. That means brand owners do not need exotic application machinery and can often convert existing labels to CleanFlake specs with limited process changes, which has been a clear selling point in industry presentations.
Designed around recyclers’ reality
One important detail is that AD CleanFlake is tuned to the industry-standard PET recycling process, not a laboratory ideal. In commercial facilities, shredded bottles run through hot caustic baths where labels and glues can contaminate the plastic stream, and Avery Dennison built CleanFlake to separate specifically at those temperatures and chemistries, as highlighted in technical case studies with PET recyclers.
When the adhesive releases, the label matrix floats to the surface and is skimmed off with other contaminants, while the heavier, now relatively clean PET flakes are recovered. Operators report that this separation reduces discoloration and haze in recycled PET, which directly improves the quality and value of the resulting rPET pellets for new bottles and trays.
Background on Avery Dennison shares
Label innovations like AD CleanFlake are part of Avery Dennison’s wider intelligent labels and sustainable materials strategy that investors follow closely.
What brand owners gain
For beverage and household brands, the promise is straightforward: meet tightening recyclability guidelines while keeping strong shelf impact. Global FMCG companies have committed to using significantly more recycled PET in packaging by 2025 and 2030, and label contamination is a known bottleneck in hitting those targets, as industry reports from packaging alliances have underlined.
AD CleanFlake is certified by recognized recycling and packaging bodies for compatibility with PET bottle recycling in Europe and North America, which helps sustainability teams tick off compliance checklists efficiently. It also allows packaging engineers to keep using high-opacity, full-wrap labels and bold graphics without sacrificing recyclability scores.
The numbers behind the material
Avery Dennison offers AD CleanFlake across several film constructions, including clear, white and metallized options with different thicknesses, to cover everything from small water bottles to large detergent containers. Product data sheets list options such as 50 µm films combined with the proprietary wash-off adhesive, allowing converters to dial in stiffness and conformability for specific container shapes.
In trials shared by the company, PET recyclers have reported higher yields of food-grade rPET when CleanFlake labels are used compared with conventional pressure-sensitive labels. Exact percentages vary by stream and facility, but the direction is consistent: fewer specks, less yellowing and a smoother pellet output, which translates directly into economic value for the recycling chain.
Where it still has limits
There are, however, practical limits. AD CleanFlake only delivers its benefits in systems that use hot caustic wash and density separation, so in regions with less advanced recycling infrastructure the effect can be muted. And if labels are oversized or poorly applied, they can still trap residues or cause mechanical handling issues in sorting lines.
Printing and converting also need attention. Ink systems must be compatible with the wash-off concept, and converters have to follow Avery Dennison’s process guidelines to avoid things like heavy varnish build-up that could affect separation. That is where the experience of label partners really matters for getting consistent performance.
A human face to the project
Deon Stander, president and CEO of Avery Dennison, has repeatedly framed solutions like AD CleanFlake as central to the company’s sustainability agenda, telling investors that design for recycling is now a core pillar of product development in the materials group. On the technical side, product managers in the Label and Graphic Materials division have worked with major beverage brands and recyclers in pilot programs, fine-tuning the adhesive behavior based on feedback from real sorting lines rather than solely lab tests.
Walk through a modern bottling plant, and you can see the result: reels of CleanFlake-based labels running at full speed on standard labeling machines, indistinguishable to the consumer’s eye yet engineered to behave very differently once they enter the recycling loop. That quiet shift is what executives highlight when explaining how materials science can make mass-market packaging slightly more circular.
Context and share listing
Avery Dennison focuses broadly on labeling and functional materials, from pressure-sensitive labels and graphic films to RFID intelligent labels that track goods through global supply chains. Solutions like AD CleanFlake sit alongside those higher-tech offerings and show how incremental material tweaks can support large customer sustainability goals without a visual overhaul on shelf.
Avery Dennison shares (ISIN US0536111091) are listed on the New York Stock Exchange in US dollars, and recycling-friendly label platforms like AD CleanFlake form part of the company’s narrative around long-term demand in packaging and retail.
