Brook + Whittle has been granted a U.S. patent for its GreenLabel BlockOut innovation, a recyclable light-blocking shrink sleeve solution designed for PET packaging. This solution, identified by U.S. Patent No. 11,961,422, has attracted attention globally from major consumer packaged goods (CPG) brands striving to meet their 2025 recyclability goals with stakeholders and organizations such as the US Plastics Pact.
The GreenLabel BlockOut technology allows brands to transition from traditional problematic plastics to clear PET packaging, which offers advantages in sustainability and recyclability. It features a unique light-blocking coating, essential for products in sectors like dairy, beverages, and nutraceuticals, where light exposure can cause spoilage, nutrient loss, and flavor alterations. Previously, these products were often packaged in colored PET, which has limited recyclability and market value and contributes to a higher carbon footprint. The new technology supports the use of clear PET, which is more environmentally friendly, widely accepted by recycling systems, and can be recycled multiple times without contaminating the recycling stream.
Tyler Matusevich, Director of Sustainability at Brook + Whittle, mentioned that the development of this technology included eight years of research and development, incorporating de-inkable inks and a functional barrier coating. The company has conducted multiple commercial-scale trials to ensure the technology’s recyclability and functionality.
Daryl Northcott, Executive Vice President, expressed that the patent marks a significant milestone for Brook + Whittle and its clients. The company is actively supplying commercial-scale orders and collaborating with various brands to ensure a smooth transition to this new packaging solution, underscoring its commitment to leading sustainable packaging innovations.
