700ml bottle is Rockware first

Packaging News, 01 December 2006

 

Rockware Glass claims to have produced its first 700ml spirit bottle that weighs in at less than 300g.

 

The company’s design and production team have spent 18 months developing the bottle, which weighs 298g and was created using the narrow-neck press and blow technique.

 

 

The lightest 70cl bottle previously created by Rockware weighed 340g.

 

Spokesman Simon Morgan attributed the reduction in weight to a more even spread of glass over the shape of the bottle but without weakening the overall structure.

 

The company said the lightweight bottle could be mass-produced but retained the strength and impact characteristics of a heavier bottle.

 

Morgan said the company was confident that the light-weight bottle would help glass maintain its position as the premium packaging material for spirits.
