Nestlé Waters says new coating on its 50-ml San Pellegrino PET water bottles reduces weight, increases carbon retention and shelf life by three months; company installs two new coating machines at bottling plant in Bergamo, Italy

LOS ANGELES , April 5, 2012 () –

Nestlé Waters indicates that a new silica dioxide coating on its 500-milliliter (16.9 ounces) polyethylene terephthalate bottles used for its San Pellegrino brand reduce weight and increase carbon retention and shelf life by three months, reported BeverageDaily.com on April 5.

To develop the technology, Nestlé Waters worked with an unnamed partner that had supplied the coating to brewers for years, said Valeria Norreri, Nestlé Waters international marketing manager.

The Switzerland-based company, which is the first global water brand to use the coating technology, has installed two new coating machines that run at the rate of 24,000 bottles an hour, on its 500-ml bottle production lines at the San Pellegrino Terme Plant in Bergamo, Italy, BeverageDaily.com reported.

Nestlé Waters focused on the 500-ml size because there was a faster carbonation loss from this size than from larger formats, the company said. Currently, the supplier technology is not available to work on bigger sizes, said Norreri.

The new silica dioxide coating, which is applied in a thin film to the bottle’s internal surface, has been approved by the European Food Safety Authority and the U.S. Food and Drug Administration, according to Nestlé Waters, reported BeverageDaily.com.

The coating results in a bottle that weighs 17% less without changing the bottle’s shape or color. Beverages packaged in the bottle have carbonation retention and product shelf life that lasts for 15 months, up from the current 12 months, said a Nestlé spokesperson.

San Pellegrino packaged in the new bottle is already on the market but consumers have not seen a price increase, said Norreri, noting that although production costs are higher for the new technology, it allows for lightweighting the bottle and adds value in terms of eco-benefits, BeverageDaily.com reported.
