Coke Bottles Get Lighter

Posted on:


‘Coke taste better from a glass bottle’ is probably the most common phrase we hear from our fellow Friends of Glass. It’s no surprise really. Glass is inert and so doesn’t interact with what it holds, which is why it’s simply the best protector of flavour and freshness.


Glass bottles clearly have some brilliant advantages: they look great, they are better for your health and the environment, and are also getting much lighter too! UK glass manufacturer Ardagh has designed a new 330ml glass bottle for Coke weighting just 190g that is 26 per cent lighter than its comparable 2005 bottle.


Amazingly, the new bottle retains all the bottle’s trademark dimensions, quality and strength. Talking about the new and improved design, Carsten Berkau, Design Manager for Glass Europe at Ardagh, said:  “Lightweighting is an ongoing process through well-established design and manufacturing techniques. Our task is to keep the famous shape, whilst determining the stress points and the optimum weight of a glass bottle. State of the art technology ensures that when we are challenged, we can respond with even greater precision.”

Glass Bottles Get Even Lighter!

Did you know that current glass packaging is around 40% lighter than it used to be? Lightweighting of glass bottles and jars is an important strategy adopted by the glass industry and brands worldwide to ensure a lighter carbon footprint for glass. For example, Belu, the UK’s ethical bottled water brand, has collaborated with glass packaging specialist Rawlings to produce the lightest weight glass bottle for mineral water in the UK. This new bottle will help the hospitality sector make an important reduction in carbon emissions, while using less raw materials in the process – a win-win for all.


Fast facts:

- Belu’s new lightweight bottle saves 850,000kg of glass annually – equivalent to 2.1m wine bottles

- The new bottle is trademarked ‘Ethical Glass’ and is 18% lighter than the original bottle

- Belu will reduce its carbon emissions by 11% with the new bottle – equivalent to carbon associated with 7,000 nights in an average-sized UK hotel.



Malibu’s glass bottle has also been given a new lighter weight bottle. Glass manufacturer Ardagh used  advanced design technologies to achieve best in class weights of  450g for the 70cl version and 455g for the 75cl whilst retaining all the design features of the bottle. A new clear window around the bottom of the bottle is intended to maximise shelf-appeal by highlighting the fresh, clear spirit.


Beer bottles are getting lighter too! Ardagh also has produced a new lighter weight 660ml bottle for Innis & Gunn’s Original and Rum Finish beers. Moving to lower weight glass bottles will considerably lessen the brewer’s environmental impact. The combined weight reduction – the 330ml bottle now weighs 195g, down from the current 245g – will represent a saving of 2,000 metric tonnes of CO2 over the next three years.



Cheers to Belu, Innis & Gunn’s Original and Malibu from Friends of Glass!
