CAPS & CLOSURES 49 PETplanet Insider Vol. 21 No. 07+08/20 www.petpla.net Special thanks must go to David Chalmers of Coca-Cola Amatil who spoke to us from Sydney at ten o’clock in the evening. He highlighted the perspective of the user. Although the use of tethered caps is not yet mandatory in Australia, David wants to be prepared because it is only a matter of time until they are intro- duced there. Amatil is also developing new packaging of its own and prepar- ing case studies, in particular the challenge regarding lightweight bottles and closures. He also showed us how the process influences cap design. German Technology PETinars - specialist webinars created by and for the PET sector! We are bringing together experts and key figures from across the sector. Topics will be chosen based on particular PETplanet Insider focus themes, with participation free of charge for our readers. Using the example of caps used by Amatil up until now (PCO 1881, Hotfill PET 26/22 and 38mm aseptic), he showed us how they envisage the tethered cap. Based on the PCO 1881, which has been in use since 2012, the idea is to merely replace the slitting sides in the mould in order to produce a tethered cap. This would be the equivalent of around 10% of a new mould. This is different with PET 26/22 which needs completely new cavities and amounts to around 70% of the original mould investment. On the other hand, it is sufficient to change the slitter with the 38mm aseptic and 1881 Hotfill. Using the example of the 600ml Powerrade Hotfill, Chalmers showed us the speci- fications of the 1881 Hotfill. He also briefly explained the manufacture and assembly of the three-part closure, slider and overcap. He has no teth- ered solution for the overcap as yet.
