New patented technology for hot-fill PET bottles: Active base inversion

摘要

Sidel BoostPrime is a unique PET packaging solution,offering an alternative for hot-filled beverages in PET bottles.This patented solution is addressing the single serve market of JNSDIT Quice,nectar,soft drink,isotonics,tea)filled in PET bottles of up to 1.21 at a temperature of 85-88 °C.The BoostPrime packaging solution removes the need for restrictive vacuum panels or gas addition into PET bottles normally required for the containers to resist hot-filling temperatures.The final bottle shape is achieved with an active base inversion and relies on three key features with minor impact on the packaging manufacturing line layout: ■ The packaging design requires specific base geometry and specifications.n 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.
