Development of Packaging Containers Based on the 4Rs

In the field of packaging containers, we are working to develop technologies from the perspective of the 4Rs (reduce, replace, reuse, and recycle) with the aim of developing products that are friendlier to the environment.

From the perspective of reduction, we introduce various methods of container design to make bottles thinner and as light as possible while keeping them easy to use and durable. This in order to reduce the amounts of plastic used.

In terms of replacement, we are striving to solve technical issues while shifting from petroleum-derived plastic to lower-carbon, renewable plant-derived plastic and other sustainable raw materials.

Regarding reuse, we are actively promoting the development of refill and replacement products so that main containers such as bottles and pumps can be used many times over. We developed and are promoting the use of Raku-raku Eco Packs, which make it easier to refill containers, Smart Holder, with which you can simply replace the main containers, and Raku-raku Switch, which you can use by hanging a container of a product and using it as-is.

With respect to recycling, we are working to introduce more recycled resin in plastic packaging containers. Kao has developed technologies for recycling multi-layer refill packs made of various materials, and is striving to help bring about a society that actively recycles resources for plastic packaging containers.
