The new 4020G grade offers up to 50% lower haze and reduced impact on the PET recycle stream compared to previous grades, while maintaining the same reli- able active oxygen scavenging performance, as the company states. Additives are often included in PET packaging to help protect contents and extend shelf life, but they can decrease packaging clarity. This in turn affects consumer perceptions of product appearance and brand value. To support the move toward a circular economy, govern- ments are legislating increased levels of recycled material in single-use packaging. For example, an EU directive for use of rPET in beverage bottles will increase from 25 per cent in 2025 to 30 per cent in 2030. As a result, brand owners need to ensure the oxygen scavengers used in their PET bottles maintain efficacy as increasing levels of rPET are introduced. Avient testing shows that ColorMatrix Amosorb 4020G is a robust oxygen scavengers for PET rigid containers, with negli- gible effects on efficacy for the rPET grades tested, while other competitive materials lost almost all oxygen scavenging ability with rPET content as low as 20 per cent. ColorMatrix Amosorb 4020G is available with applicable regulatory approvals. www.avient.com New application for trinamiX Near- Infrared Spectroscopy: plastic sorting trinamiX GmbH, a wholly owned subsidiary of BASF, announced it has developed a new application for its mobile Near-Infrared (NIR) Spectroscopy Solutions related to plastic sorting and recycling. Using trinamiX technology, the diverse compositions of different plastics can now be precisely deter- mined and thus distinguished via the simple use of a portable handheld device that combines trinamiX data analysis with a mobile app, states the company. NIR spectroscopy is a proven technology and used in laboratories around the world – the innovation is the port- able format of the spectrometer and the sophisticated data analysis that can now be processed in the field via wireless cloud uploading. Slightly larger than a mobile phone, the spectrometer has nearly universal use cases. With the help of trinamiX NIR Spectroscopy Solutions, all common plastics are said to be now identified within seconds. The spectrum ranges from classic polyolefins such as PE, PP and PVC to PET. In addition, technical plastics such as or PA can also be correctly identified in the field (especially in blends with other plastics). trinamiX can integrate additional materials according to customer requirements. The company states that wherever quick identification has an advantage, the trinamiX solution is a good decision aid. In recycling, for example, it is aimed at companies that do not need a large, stationary sorting plant, but a flexible and mobile solution. Examples include recycling yards and plants as well as manufacturers of recycled goods. The solution is also interesting for decommissioning companies and large dealers. www.trinamiXsensing.com
