Previoulsy standard weight was 450g and the 340g bottle was manufactured through a narrow neck press and blow process.
According to Nampak, this enabled the glass to be distributed more evenly during the manufacturing process. It added that annual volumes for the general trade for the first year are “modestly estimated” at 2m units for the 340g version, saving 60tons of raw material.
The first brand to use the new bottle is Douglas Green Bellingham’s (DGB) high volume Culemborg range.
“To illustrate its significance, consider that this brand was previously offered in the standard 450g bottle,” said DGB general manager of operations Pieter Marais. “The lightweighting therefore represents a 24% weight reduction in glass and the reduction in carbon dioxide equivalent emissions on the brand alone is estimated to be over 100tons a year.”
