According to the brand, this change in packaging is a "response to consumers' desire for freshness." The transparent PET bottles to be used by Letti have a one-liter yield and are designed by [Amcor](https://www.trendhunter.com/trends/danone-yogurt-jar). New features include a simple new bottle cap system and for some products, like the Lettico A2 fermented [milk](https://www.trendhunter.com/trends/kiehls-x-milk-bar) bottle, the foil seal barrier is eliminated. In addition, the transparent PET bottles have some protective features to optimize the freshness of products. This includes a thicker wall to avoid deformation, as well as a 38-mm finish and an ultraviolet blocker to protect the contents of each bottle.
