Compostable labels and credible claims: How Sinclair -T55 sets the standard in a scrutinized market 

As sustainability becomes a crucial part of packaging innovation, so too does the scrutiny that surrounds environmental claims. A recent article in Packaging Europe¹ highlights how EU law continues to protect consumers from misleading sustainability claims, even as the proposed Green Claims Directive has been withdrawn. In this evolving regulatory landscape, companies must go beyond buzzwords and back up their environmental messaging with verifiable, transparent evidence.

This is where Sinclair – T55 compostable fruit label stands out.

The risk of greenwashing

The EU’s legal framework targets vague or deceptive claims such as “eco-friendly” or “compostable” without proper context or certification. For example, companies have faced backlash for labeling products as “home compostable” when they are only certified for industrial composting² (T55 has certification for both)

In this climate, credibility is key. Brands must ensure that their sustainability claims are not only accurate but also easily understood and independently verified.

Providing proof over promises 

Sinclair has taken a proactive approach to this challenge. The T55 ‘finished product’ certified compostable label is not just a claim—it’s an independently verified solution. The certifications are underpinned by internationally recognized packaging standards:

• EN 13432 (EU industrial composting
• AS 5810 (Australian home composting)
• NFT 51-800 (French home composting)

These certifications are issued by independent certification bodies who verify composting test results provided by independent laboratories.

The testing process must be completely independent and transparent. A recognized independent laboratory must be used with the test results provided to an internationally recognized certification body such as – TÜV AUSTRIA, DIN CERTCO, and the Australasian Bioplastics Association (ABA).

But Sinclair didn’t stop with certification of T55. To further reassure customers and consumers, an independent laboratory timelapse video of T55 composting on a variety of fruit in home composting conditions was created . Sinclair also provides customers T55 trials demonstrating the compostable class leading label application performance (equivalent to conventional label) in real-world packing environments applying up to 720 fruits per minute per lane—and its compostability in action. Duncan Jones commented:

“It’s been our passion for over 17 years, at one point we thought we might not get to where we are now as it has been a challenging journey to this point. We’ve gone out of our way to show that our claims are not just compliant—they’re credible. In a time where greenwashing is a real concern, transparency is our strongest asset.”

Why compostability matters for fruit labeling 

Fruit labels are a small, minimized packaging alternative, but their impact is significant for growers, retailers, and consumers. In a world of excess packaging, compostable labels are an opportunity to reduce packing, reduce cost (potential EPR fees) and increase operational efficiency.

Now, with a certified compostable label that performs at scale, Sinclair is supporting its partners—like Zespri, Baika and Index Fresh in the adoption of T55. Operationally it’s a straightforward transition, no change to the current Sinclair labeling system and exceptional label application performance.

In a world where sustainability claims are under the microscope, Sinclair’s T55 label is a model of what responsible innovation looks like: certified, tested, and transparent. Sinclair’s focus is on making them smarter, compostable, and more functional. Fruit labels are not just a convenience—they’re a sustainability enabler.
