What is a “hexagonal cardboard box” to achieve both improved durability and reduced material costs?

Invented “hexagonal cardboard box” to reduce material cost

JA Zenno Nagano has devised a way to change the material and thickness of the paper in cardboard boxes to reduce the shipping costs of cardboard boxes. However, if the material and thickness is reduced, the carton will not withstand the vegetable load and will be deformed.

So I decided to review the shape of the cardboard box. I then consulted with Naganomori Paper Industry, a company I have been in for a while.

“During consultation, we proposed a cardboard box with the corners cut off. The amount of raw materials used for cardboard was reduced, leading to cost reductions and the possibility to print brand names and vegetable production areas on We recommend using it for fruits and vegetables as it can promote the area and product, ”Nakaji said.

Mori Paper Industry Co., Ltd. decided to develop a hexagonal cardboard box in cooperation with JA Zenno Nagano. Development started around July 2015. We asked six manufacturers of the Hakusai brand “Mitake Hakusai” from JA Kiso in Kiso-gun, Nagano Prefecture to test usability and test production. times.

“Our company has been delivering square cardboard boxes to JA Kiso for a while. At one point we received a request that we wanted the cardboard to be able to reduce costs and promote the brand.”

So I thought that the under development hexagon cardboard box might fit, and we suggested it to JA Kiso. It has a unique shape, is easy on the eyes, and the brand name can be printed on the cut corners. “

In November 2017, about two years after starting development, JA Kiso decided to officially use a hexagonal cardboard box. “The 15 km case of” Mitake Hakusai “was able to reduce the amount of substrate used, resulting in the price of the material, by about 3% by cutting two diagonal corners.”

Vegetables in hexagonal cardboard box

State of the corners when Hakusai is placed in a hexagonal cardboard box

The hexagonal cardboard box was developed for fruits and vegetables, but it seems that some vegetables are suitable for packaging and some are not.

“For vegetables with gaps in the corners when placed in the box, we recommend using hexagonal cardboard boxes. For example, round vegetables like watermelon and pumpkin. On the other hand, cucumbers. and onions, etc. For vegetables that do not have gaps in the corners, a common square cardboard box is preferable. “

Currently, hexagonal cardboard boxes are used to pack JA Kiso’s “Mitake Hakusai”, as well as Daikon in Ishikawa prefecture and garlic in Hokkaido.

At the same time contribute to reducing transportation costs and CO2

The strengths of hexagonal cardboard are not limited to strength and price.

By eliminating unnecessary gaps, even if the same amount of vegetables is packed, the size of the material can be small, so more cardboard boxes can be loaded on one truck, this will resulting in reduced transportation costs and CO2. Was.

Also, hexagonal cardboard boxes are easier to pack vegetables than square cardboard boxes. “Diagonal cuts are easier to fit when stuffing vegetables than normal square corners,” Nakaji said.

Currently, hexagonal cardboard boxes are mainly used in JA Zenno Nagano. Someone who actually used it said, “The corners are conspicuous and impactful. I feel it is very novel.” The response has been excellent, and recently, efforts have begun to use it in JAs other than JA Zenno Nagano.

The hexagonal cardboard box was patented in 2016. Currently, it is mainly used in the area under the jurisdiction of JA Zenno Nagano, but it is said that they will expand their proposals. for future nationwide JAs. “We are planning on releasing it to the public,” Nakaji said.

Indispensable cardboard for delivery and transportation. Of course, you can easily use the ready-made products, but why not review it while including the hexagonal cardboard box as an option?
