In 2009 and years prior to that, the Kinley 1 litre packaged drinking water bottle, used to have a neck finish weight of 3.90 grams and closure (cap) weight of 2.3 grams. Around that time, the Coca-Cola Company and its bottlers embarked on a Kinley lightweighting programme in India that was aimed at reducing the raw material –PET –abbreviation for Poly Ethylene Terephthalate, a petroleum derivative.

When the Kinley lightweighting project was completed, the neck finish weight was reduced to 2.4 grams and the closure weight to 1.3 grams, thus saving approximately 2.5 grams per bottle (40 per cent on neck + closure weight per bottle).

To further reduce the weight and PET content, the company began to use the nitro fill process which allowed more stable packaging with lesser quantity of material.

The lightweighting initiative even won the Global Innovation (Productivity) Award for The Coca-Cola Company in 2016.

Coca-Cola’s packaging process is minutely detailed and scrutinised to meet even the toughest packaging safety standards. Its quality systems require all suppliers to comply with the safety, environmental and quality standards. This includes the Food Safety and Standards Act and the Global Food Safety Initiative (GFSI) recognised Food Safety Management System Certification for all suppliers of primary ingredients and packaging material.

Coca-Cola’s efforts to create more sustainable packaging are expected to contribute to its overall goal of reducing the CO2 emissions associated with the “drink in your hand.”
