15 Aug 2019 --- Nestlé Japan is replacing the plastic wrapping on its KitKat candy bars with paper in a bid to become one step closer to its commitment of 100 percent recyclable or reusable packaging by 2025. The Japanese market’s material switch will occur across five KitKat multipack products from September 2020 and across all individual products in 2021. The switch to paper is unique to the Japanese market, where the popularity of KitKats continues to surpass that of other geographies.
