BOTTLE MAKING 33 PETplanet Insider Vol. 23 No. 06/22 www.petpla.net BOTTLE MAKING 33 with dimension checking but also more specific tests, such as DSC and IV tests, both on the preforms available on the market and on those developed and injected in-house using Husky machinery. It all depends on the customer requirements. The European SUP directive stipulates that European companies should adopt the tethered cap so manufacturers will need to take action and implement this soon. This could also be the right opportunity to revamp packaging, reduce the weight or adjust those that are not performing well. Competek has developed a tool that allows the customer to evaluate their investments taking into consideration the line parameters, the type of packaging, and the modifications required, which then helps to understand the ROI. A win-win scenario for the customer: make your packaging more sustainable and understand from the outset when you will get a return on investment. It’s worth mentioning that Competek line conversion services have no brand limitation, therefore the customer with mixed lines can count on one unique supplier providing all the parts and the installation with minimum downtime. This is our value add: one partner, lower costs, quick delivery times. PETplanet: For rPET, you offer a protocol that customers can use to work through all open questions, from preform performance to the blow moulding process and legal compliance. In an earlier interview, you told us that customers were particularly concerned that the performance of a bottle could suffer from a conversion from virgin PET to rPET. Is this still the case or are there perhaps other concerns that have come to the fore? Olivier Serre: With our certified lab, we support customers in testing the performance of a specific batch of recycled material, therefore analysing also the quality, safety and performance of the final bottle and give the customer the correct blowing process. What we see right now is that manufacturers are worried about the uncertainty of the performance for sure, but they are also worried about the colour of the final bottle that could impact on the brand image and on the overall cost of the raw material which is higher than the virgin PET at the moment.
