Description

The history of Rengo can be said to be synonymous with the history of the development of corrugated board in Japan. In 1909, Teijiro Inoue, the founder of Rengo, established Sanseisha (predecessor of Rengo), marking the beginning of commercial production of corrugated board in Japan. The origin of the corrugated board business can be traced back to the moment when Inoue, after a long and difficult effort, completed a “corrugated (dan) board (boru-gami)” product that he called “danboru.” He thought that the name sounded good and was easy to remember.

Rengo Co., Ltd. is a leading Japanese company in the packaging industry, with a rich history dating back to its founding in 1909. The company specializes in manufacturing and selling a wide range of packaging products and materials. Its main business areas include:

  1. Corrugated Packaging: Rengo produces corrugated boards and boxes, which are widely used for shipping and storage.
  2. Paperboard Products: This includes containerboards, boxboards, and tube boards, catering to various packaging needs.
  3. Flexible Packaging: The company offers film packaging, labels, and cellophane, including eco-friendly alternatives.
  4. Heavy-Duty Packaging: Rengo manufactures heavy-duty polyethylene bags, kraft paper bags, and flexible container bags.
  5. Packaging Machinery: It provides machinery for e-commerce packaging systems, box-making, sealing, and more.
  6. Functional Materials: Rengo develops innovative materials like porous cellulose beads, antibacterial agents, and tinted films.
  7. Nonwoven Products: These include water-absorbent mats, cushioning mats, and shielding sheets.

Rengo operates globally, with numerous plants and offices in Japan and overseas, and is committed to sustainability and innovation in packaging solutions.
