CAPS & CLOSURES 31 PETplanet Insider Vol. 27 No. 01+02/26 www.petpla.net SACMI advances sustainable rigid packaging Ultra-light tethered caps and new standards CAPS & CLOSURES Lightweighting and new standards Lower cap weight is still a key innovation driver. Intelligent lightweighting does not just remove weight, it enhances the entire cap-preform system. The growing popularity of the 26/22mm standard is becoming the new global benchmark, with a comprehensive range of caps for water, CSD and hot fill that maximise sustainability. The SACMI UniAqua 25/22 and 26/22 family delivers a short-neck closure solution that features a shared upper mould. This approach lets producers make different cap types with the same upper mould. SACMI says that this solution offers high manufacturing flexibility, lower investment costs, fast size changeovers and appropriate aesthetics and functionality. This range also includes SACMI UniAqua 26/22 Tethered Ready, designed to meet regulatory and market requirements regarding tethered caps. The AB26WT2 model is designed to be compatible with all major tethered patterns, including TCHO (ThisCap HoldOpen), which is known for its flexibility and ease of use, states SACMI. Tethered: a simple and sustainable transition Adopting the tethered standard - already mandatory in Europe and increasingly in demand worldwide - is a significant technical and industrial challenge for manufacturers. SACMI provides ready-to-use solutions to the market. An example is the AB26CSDT5 GME 30.40 26/22mm cap, which allows manufacturers to transition to tethered operations while maintaining high levels of productivity and quality. Towards a complete packaging ecosystem In parallel, the transition from the still widely used PCO 1881 standard to GME 30.40 continues. It reduces the use of virgin raw materials and is fully compatible with state-of-the-art bottling lines. By taking a systemic approach that integrates cap, preform, mould and process technology, SACMI claims to provide customers with close support throughout the process. Solutions for ultra-light, tethered-ready, high-performance caps are part of a comprehensive system that integrates product development, process technology, and quality control. This approach aims to help brand owners and converters in meeting regulatory, environmental, and competitive requirements by focusing on efficiency, sustainability, and consistent product quality. www.sacmi.com In the rigid packaging sector, caps continue to play a crucial role in reconciling sustainability, industrial performance and consumer experience. Against this backdrop, cap and preform technologies are evolving rapidly, driving the market towards lighter, more flexible solutions that meet new international standards.
