BOTTLING / FILLING PET planet Insider Vol. 20 No. 03/19 www.petpla.net 18 New patented technology for hot-fill PET bottles Active base inversion Sidel BoostPrime is a unique PET packaging solution, offer- ing an alternative for hot-filled beverages in PET bottles. This patented solution is addressing the single serve market of JNSDIT (juice, nectar, soft drink, isotonics, tea) filled in PET bottles of up to 1.2 l at a temperature of 85-88 °C. The BoostPrime packaging solu- tion removes the need for restrictive vacuum panels or gas addition into PET bottles normally required for the containers to resist hot-filling tem- peratures. The final bottle shape is achieved with an active base inver- sion and relies on three key features with minor impact on the packaging manufacturing line layout:  The packaging design requires specific base geometry and speci- fications.  The Base OverStroke System (BOSS) allows the mechanical forming of the bottle base during the blowing process.  The inverter contributes to the base inversion. This step takes place after filling and capping, tilting and cooling and before labelling. It balances the negative pressure induced by the beverage cooling in the bottle from 85°C to ambient temperature. Increased packaging appeal to stand out on the shelf The removal of the technical con- straints of the bottle vacuum offers total freedom of shape in order to attain premium and distinctive PET bottles. It allows a uniform look and feel for hot and aseptically-filled bottles for consistent brand image. Any iconic bottle shape with panels can be easily adapted without impacting the consumer perception. Besides that, it enlarges the brand- ing opportunities as the bottles’ labelling surface with no vacuum panel is smoother and contributes to a greater and more impactful look and feel. The labelling quality for both roll-fed labels and sleeve labels is highly improved due to an inner bottle pressure during label applica- tion. Filling Special
