CPBR is the Japanese industry body responsible for promoting and evaluating the recycling of PET bottles. CPBR sets voluntary design guidelines for PET bottles and conducts thorough evaluations of new materials to ensure compatibility with Japan’s advanced recycling systems. Approval from CPBR is essential for any new material to be accepted into the Japanese PET bottle recycling stream, helping maintain the integrity and efficiency of the country’s recycling infrastructure.
Following a rigorous evaluation process, CPBR has assessed Avantium’s PEF, marketed under the releaf® brand, for use as a barrier layer in multilayer PET bottles. The CPBR report confirms that PEF can be safely and effectively recycled within the existing PET stream at concentrations up to 10% weight. The material met key tests for physical, chemical, and processability criteria, and complies with Japan’s Positive List system for food contact plastics, the Standards and Criteria for Foods and Additives issued by Japan’s Ministry of Health, Labour and Welfare, as well as FDA regulations. The overall recyclability rating for PEF-containing bottles was ranked “A”, indicating full suitability for bottle-to-bottle recycling. The CPBR approval in Japan follows similar recycling recognitions in Europe (by the European PET Bottle Platform) and the USA (by the Association of Plastic Recyclers). These endorsements empower brand owners and converters to confidently adopt PEF as a barrier layer, supporting the beverage industry’s transition to renewable, high-performance, and recyclable packaging.
