Brook + Whittle has been awarded a US patent for its GreenLabel BlockOut, a recyclable light-blocking shrink sleeve solution for PET packaging.
According to the company, the patented solution (US Patent No.: 11,961,422) has received worldwide interest from many large CPG brands as they push hard to find solutions to help them achieve their 2025 recyclability commitments to shareholders and NGOs like the US Plastics Pact (USPP).
Brook + Whittle’s GreenLabel BlockOut enables brands to shift from problematic plastics to clear PET packaging while protecting their products with a unique light-blocking coating. It is designed to be fully compatible with existing recycling processes, ensuring it does not contaminate the recycling stream.
“At Brook + Whittle, we’re committed to providing packaging solutions that balance aesthetics, performance, cost, and sustainability,” said Tyler Matusevich, director, sustainability.
“This solution does just that. After eight years of R&D, we have developed a patented solution that utilises a crystallizable shrink sleeve, our GreenLabel de-inkable inks, and a functional barrier coating. We successfully conducted multiple commercial-scale trials to ensure the correct sortation and recyclability of this light-blocking shrink sleeve.
“Alongside the recyclability benefits of this solution, we expect our customers will benefit from switching to clear PET and lower their extended producer responsibility (EPR) eco-modulation fees in the future,” said Matusevich.
Daryl Northcott, executive vice president, said the patent marks a significant milestone for Brook + Whittle and customers.
“We are currently supplying commercial-scale orders and are working closely with multiple brands to ensure a smooth transition to this product. Being first to market with this patented solution is a testament to our ongoing commitment to leading the way in sustainable packaging and driving the industry forward.”
