The evolution of packaging is supported
by the latest research and development capabilities.

Research & Development

Changing the future of packaging with unprecedented functions,
materials, and manufacturing technologies

  • As the first company in Japan to become involved in the corrugated business, and lead the industry as a pioneer, Rengo has continued to develop numerous innovative functions, materials, and manufacturing technologies which open up the possibilities of packaging. We support ever-evolving packaging with the latest research and development capabilities, including paperboard production technology that achieves lightweight containerboard; functional corrugated packaging such as water resistance, moisture proofing, fire retardancy, and low friction; and development of adhesives that improve production efficiency.

Developing a variety of functional materials
beyond packaging to make life comfortable

  • Materials and products created through Rengo’s research and development are also used widely in fields other than packaging. An example includes the high-function fiber Cellgaia with uses such as in antibacterial kitchen cloths. Gaiaphoton—a luminescent phosphor that does not contain any rare earth—is expected to be used in applications such as lighting, cosmetics, and anti-forgery technologies. In addition, we are also working on research into the practical applications of cellulose nanofiber which has gained attention from various industries.

Bringing innovation to packaging through research and development
in collaboration with design and manufacturing frontlines

  • To meet high-level needs, it is important to not only develop new functions, but also improve quality from various angles, such as planning, manufacturing, and design. At Rengo, we give birth to many innovative packaging solutions by carrying out research and development while sharing and collaborating on issues with various units.

Pursuing safety and peace of mind is also
the responsibility of a leading company

Rengo—which also offers many packaging products for food and beverages—conducts chemical analysis on material properties, product quality, impact on the environment, and so on. We believe that the pursuit of safety and peace of mind is the responsibility of a leading company, and also work on improving analysis technology.
