The beverage industry is rewarding operating strategies of companies with solutions for making lighter containers . But that is not all; their strategic vision must include business models that provide significant cost reductions in all phases of the production process.
Over the last two years, SIPA has created bottles, production and hot-fill systems for cylindrical containers of various shapes which have a petaloid base, are panel-free, and can be labeled with a regular, wrap-around label.
Filling occurs at 85° – 87° degrees centigrade. A dose of liquid nitrogen immediately prior to capping results in 1.5 bars of internal pressure. After the beverage cools and its volume contracts, the internal pressure remains at 0.2 - 0.3 bars, ensuring rigid packaging and ease of labeling.
Advantages
This type of bottle reduces costs significantly:
• the container is more lightweight due to the elimination of the side panels which are no longer necessary because a vacuum is no longer being created.
• the wrap label costs approx 30% less than the typical shrink labels required in traditional hot-fill bottling.
This application was created by SIPA to meet the requirements of a particular customer that needed to considerably reduce the cost of their primary packaging (bottle-cap-label); at the same time they needed to use hot-fill technology to ensure their products were of the highest quality without resorting to preservatives (fruit juices, isotonics, teas).
