Coca Cola and Pepsi changed 600 milliliter (ml) bottle to 500 ml recently, along with changing the smaller pop can from 355 ml to 330 ml.

Coke said they're using smaller sized bottles as part of a global campaign, while Pepsi said they found Chinese consumers prefer smaller bottles following an 18-month long market survey.

Local beverage manufacturer Master Kong has also changed bottle package from 500 ml to 450 ml.

The report quoted marketing expert Zhu Danpeng, saying there might be more beverage companies minimizing their packaging since high inflation has made raising prices a very sensitive issue.
