Rengo Develops Delta Flute Corrugated Board on Concept of "Less is More"

Print Print this article | Send to Colleague

Rengo Co., Japan, this week announced that it has developed and will begin selling Delta Flute, "a new standard for corrugated board." The company notes that corrugated board is a type of architecture unto itself, adding that it has successfully created a product that is the further evolution of "less weight/less carbon" through the trinity of functionality, strong construction, and attractiveness—"the architectural design concepts that have been prized since the time of ancient Rome."

Based on the concept of "less is more," Delta Flute is a new innovation in corrugated board that creates great value with few resources, Rengo explains, pointing out that Delta Flute is a type of corrugated board with a thickness midway between B-flute, which has a thickness of approximately 3 mm and is used for purposes such as canned beer packaging, and E-flute, which has a thickness of approximately 1.5 mm and is used for purposes such as gift boxes. "This original product is a brand new standard that has never existed. Rengo will approach its users regarding conversion to this product as one effort to realize the widespread use of corrugated packaging that is more lightweight and more functional in order to further reduce impact on the environment," the company said.

Overview of Delta Flute corrugated board:

  • Thickness = approximately 2 mm
  • Number of flutes per 30 cm = 60 plus-or-minus 2
  • Offers greater transportation and storage efficiency than B-flute, accomplishing the further optimization and streamlining of packaging
  • Carbon dioxide emissions are reduced and impact on the environment is mitigated through further reduction of corrugated board weight
  • Has greater flat crush strength than B-flute
  • Because Delta Flute is stronger than E-flute, it can be used as outer corrugated packaging with the functions of inner boxes.

Production is scheduled to begin at all of Rengo's corrugated plants in Japan this spring.
