Choosing a PET bottle is only one part of designing packaging with recyclability in mind. The label is part of the package, too.
For pressure sensitive labels, the facestock, adhesive, inks, coatings and other components can influence how the package behaves when it reaches the recycling stream. That means the question isn’t simply whether a label is “recyclable.” Brands need to consider how the complete label construction works with the PET container throughout its useful life and at end of life.
So how do you get the branding, functionality and performance benefits of a pressure sensitive label without overlooking PET recycling?
Why the Label Matters in PET Recycling
PET packaging is sorted, processed into flake and washed as part of the recycling process. What happens to the label during those steps matters.
The Association of Plastic Recyclers (APR) identifies adhesive behavior as one important consideration. Adhesives that wash cleanly from PET and remain with the label are preferred, while adhesive that stays on the PET or redeposits during washing can become a source of contamination or discoloration in recycled PET.
This is why a recyclable PET container should not be evaluated independently from its decoration. The label, adhesive and printed components are all part of the package design.
It’s Not Just the Label Material
A label film may get most of the attention, but recycling compatibility depends on more than the facestock.
Facestock
The label material needs to be evaluated based on how it behaves during the applicable PET recycling process. Film type, density and the rest of the label construction can influence separation.
Adhesive
The adhesive has two jobs that can pull in different directions: it needs to keep the label securely attached throughout the product’s useful life, while a recycling-aligned construction may also need to release appropriately during PET processing.
Inks and Coatings
Ink systems, varnishes, coatings, laminations and heavy decoration can affect the complete construction. They should be evaluated alongside the label film and adhesive rather than treated as purely aesthetic choices.
The Container
The same label construction may not be the right answer for every package. Container resin, product environment, application requirements and recycling objectives all need to be considered together.
The takeaway is simple: recyclability is a package-design question, not just a material-selection question.
How Wash-Off Pressure Sensitive Labels Work
Wash-off pressure sensitive labels are designed to address one of the challenges that labels can create in PET recycling.
Fortis Solutions Group’s RENEW™ RFP-02 pressure sensitive label solution uses a water-based wash-off adhesive designed to separate from the PET substrate during the water-bath stage at the recycler. Fortis offers the construction with clear, white and metallized film face materials.
The RENEW™ data sheet also lists an option for a liner made with 90% post-consumer recycled PET. That recycled-content liner is a separate sustainability attribute from the recycling compatibility of the finished PET package; both can matter, but they describe different parts of the packaging system.
Fortis’ current technical documentation identifies RENEW™ RFP-02 as recognized by the Association of Plastic Recyclers (APR). As with any package, the final construction still matters. Inks, varnishes, laminations and other additions can affect recycling performance and should be evaluated as part of the complete design.
Designing Pressure Sensitive Labels With PET Recycling in Mind
A better sustainability conversation starts with the actual package and how it needs to perform.
When evaluating a pressure sensitive label for a PET container, consider:
- What type of PET container is being labeled?
- Which facestock and film construction fit the package and recycling objectives?
- How will the adhesive behave during the recycling wash process?
- Could inks, coatings, varnishes or laminations affect the construction?
- What does the label need to withstand during use, such as moisture, refrigeration, abrasion or chemical exposure?
- Will the label work with the existing application equipment and production requirements?
- Has the complete package been evaluated against current APR guidance?
Fortis can help brands review these variables together, including wash-off or recycling-aligned adhesives, film constructions, ink and coating considerations, PET compatibility and relevant APR guidance.
What Does APR Compatibility Mean?
Terms such as “APR certified,” “APR recognized,” “recyclable” and “recycling compatible” should not be used interchangeably.
APR publishes design guidance and testing protocols intended to evaluate how packaging designs and components perform in plastics recycling systems. The appropriate claim depends on the specific construction and the recognition or testing it has actually received.
For example, Fortis’ current RENEW™ RFP-02 solution is recognized by APR. The same data sheet also notes that laminations, varnishes, inks and additives can affect package recyclability and recommends testing to APR guidelines.
For brands, that distinction is useful. Instead of asking only, “Is this a recyclable label?” ask how the complete label and container construction aligns with the relevant recycling guidance.
Performance Still Matters
A pressure sensitive label designed with recycling in mind still has to perform as a label.
Depending on the application, it may need to maintain adhesion through refrigeration or moisture exposure, resist abrasion, preserve print quality, withstand contact with oils or chemicals, or run efficiently on existing application equipment.
Shelf appeal matters, too. Brands should not have to treat sustainability and design as unrelated conversations. Materials, adhesives, inks, coatings and finishes can be evaluated together to find a construction that supports both the package’s in-use requirements and its end-of-life goals.
Build the Label Around the Whole Package
There is no single pressure sensitive label construction that solves every PET packaging challenge.
Fortis works with brands to evaluate the container, label material, adhesive, printing, decoration and application requirements as a system. For brands exploring PET recyclability, RENEW™ wash-off pressure sensitive labels provide one option designed specifically around PET container recycling.

FAQs About Pressure Sensitive Labels and PET Recycling
Are pressure sensitive labels recyclable?
It depends on the complete package. Facestock, adhesive, inks, coatings, container resin and the applicable recycling process can all affect recycling compatibility. A pressure sensitive label should be evaluated as part of the full packaging construction.
Can pressure sensitive labels be used on recyclable PET bottles?
Yes. Pressure sensitive labels can be designed for PET applications with recycling considerations in mind. Material selection, adhesive behavior, ink and coating choices, and the final package construction all matter.
What is a wash-off adhesive?
A wash-off adhesive is designed to release appropriately from the container during specified recycling wash conditions. For PET recycling, the objective is to prevent adhesive from remaining on or redepositing onto PET flake during processing.
Does APR certify pressure sensitive labels?
APR provides design guidance, testing protocols and recognition programs for packaging designs and components. Rather than assuming a label is broadly “APR certified,” brands should confirm the exact APR status of the specific construction and evaluate the complete package against current guidance.
