Weight reduction earns Coca Cola gold
Coca Cola took the 2008 Gold medal in the “Environment - Pack Optimisation category at the prestigious annual UK Starpack Awards for its lightweight contour glass bottle manufactured by Ardagh Glass. Judges were impressed by the 20 per cent reduction in weight to 210g whilst maintaining the bottle's iconic identity.The lightweighting project has been the result of several
years of work led by Coca Cola’s US based technical
consultants, and Ardagh. Ardagh chose the NNPB method in preference to the blow and blow used
by another manufacturer involved in the project.
The trademark “Contour” shape has been retained despite reducing the height from 218mm to
205mm and slightly widening the body. The new design saves 3,500 tonnes of glass raw material in
the UK alone - as well as an estimated 2,200 tonnes of carbon emissions each year. The new 330ml
Coca-Cola, Diet Coke and Coca-Cola Zero bottles weigh in at 210g, compared to the 263g original
The US based design team at Coca Cola and Ardagh worked with advanced software that can
determine the best weight for a glass bottle and point out possible weaknesses with any design.
“The technical achievements made by Coca-Cola and Ardagh prove that glass packaging can meet
the highest sustainability credentials without compromising the premium, iconic brand. ”
