Nestlé Waters announces a new coating for its San Pellegrino PET water bottles
May 16, 2012
Nestlé Waters recently announced that an innovative silica dioxide coating added to San Pellegrino PET water bottles will reduce their weight, improve their carbon retention and increase their shelf life by three months.
The company said that it was the first global water brand to use the coating technology which delivers a weight reduction of up to 17% without changing the bottle shape or colour, and which has been approved by the European Food Safety Authority (EFSA) and the US Food & Drug Administration (FDA).
A Nestlé Waters spokeswoman told the media that the technology "allowed for a better capacity of carbonation retention and extended product shelf life from the current 12-month period to 15 months.”
“The PET bottles treated with the coating guarantee perfect carbonation of the water, despite temperature changes during transport, the time delay between the filling of the bottles and their consumption, and, finally, weather differences between destination countries”, she continued.
The company noted that San Pellegrino sparkling water packaged in 500 ml bottles had suffered from a faster loss of carbonation than the larger formats, and that the new coating solved this problem.
The technological advance has led Nestlé Waters to install two new coating machines within its 500ml bottle production lines located at the San Pellegrino Terme Plant in Bergamo, Italy.
