New standards for tethered caps, lightweight necks and recycling will be exhibited by Sacmi at Interpack 2023, Düsseldorf, from 4 to 10 May, with the aim of providing solutions for seizing green transition opportunities. On the cap manufacturing front, Sacmi has already implemented the EU Directive that requires adoption of the new tethered standard from 2024 onwards thanks to a complete range of caps and profitable methods - such as post-process slitting and integrated quality control - to respond to market requirements and guide the green transition.
In recent years, few industries have focused as sharply on sustainability as packaging has. As the data clearly shows, container and cap weights have fallen by 50% or more since 2010. The latest developments in this area include the 26/22 mm (with the 25/22 variant) and the new lightened 29/25 mm necks, a set of standards on which the Sacmi Laboratory has developed ready-to-market solutions that can cut neck+cap plastic consumption by 30% or more. A concrete example is the new “tethered-friendly” caps for GME 30.40 necks and the 26/22 caps for water which combine increased height with considerable raw material savings. From a 3Rs (reduce, reuse, recycle) perspective, the PET supply chain is the one best suited to a circular economy approach, from resin recycling to finished containers for food use. That’s why Sacmi has long since ensured its preform injection presses are able to process up to 50% PET in recycled flake form, a figure that can rise to 75% with the latest developments being introduced.
