Our products are based on reliable technology. In the development process we try tons of different materials. The variation of the seal geometry can be of hundreds. After all the experiments on these numerous samples and parameters, we can accomplish the development of a closure.

As our lifestyles are changing, many situations have become dramatic. Food and beverages with various containers also play a role as well as the closures. Closures should provide good sealing function as a basic function. They should be outstanding as well as functional. In every life situation, closures play sometimes a supporting role and sometimes a leading role. Our technical development is not limited to the closure. Application of the technology to develop new markets is pursued for the future business. JCC is looking at both present and future and provides closures for any situation.

We also take care of environmental and resource issues that have been very important lately. We have developed non-PVC liner material and recyclable-caps that can be separated from a bottle after use. Our ideas are always based on recycling and reuse for production. Being friendly to the earth is another theme of JCC. The more the number of kinds of containers increases, the more the number of different materials and shapes. We have the Toyo Seikan Group Laboratory, where the basic technology is pursued. Then our R&D can develop new and proprietary products, looking at present and future business opportunities.
