Designed for product premiumisation and revenue generation, the new patented BoostPRIME solution has been developed for the single serve market of juice, nectar, soft drink, isotonics and tea (JNSDIT).
BoostPRIME will help fill beverages in PET bottles of up to 1.2l at a temperature between 85°C and 88°C.
The new packaging solution will enable to avoid use of restrictive vacuum panels and additional gas into PET bottles generally required for the containers to resist hot-filling temperatures.
An active base inversion process will allow to create the final bottle shape and reduces the impact on the packaging manufacturing line layout.
The packaging design is said to require specific base geometry and specifications, while the base overstroke system (BOSS) enables supports the mechanical forming of the bottle base during the blowing process.
The inverter will extend support in the base inversion. It will happen after filling and capping, tilting and cooling and before labeling and enables to balance the negative pressure induced by the beverage cooling in the bottle from 85°C to ambient temperature.
Elimination of the technical constraints of the bottle vacuum will lead to freedom of shape, which will help create better PET bottles. It also helps to provide a uniform look for hot and aseptically-filled bottles.
As a result of an inner bottle pressure during label application, the labeling quality for both roll-fed labels and sleeve labels have been improved.
BoostPRIME packaging solution will also help decrease the consumption of PET resin, enabling to decrease the current heat resistant (HR) bottle weight by up to 30% compared against regular HR PET bottles.
The packaging solution will help producers to use less label material, as it supports to switch from sleeve to roll-fed label application.
The bottle lightweighting potential is estimated to be between 3g and 7g due to shift from regular HR bottles with vacuum panels decorated with sleeve labels to lightweighted BoostPRIME bottles decorated with roll-fed labels.
Once of the major beverage producers from Mexico has selected Sidel BoostPRIME packaging solution and successfully started industrial production.
