Packaging Technology
We solve packaging issues by
optimizing packaging design.
Pursuing and proposing the best packaging taking into consideration
product characteristics and distribution flow
Various functions and qualities are required of packaging to deliver precious products safely to consumers while protecting these products. Rengo designs packaging and selects materials taking into consideration various factors, including the characteristics of products; strength and shock absorption based on transportation, storage, and other logistics conditions; and stacking efficiency on palettes. Furthermore, we pursue and propose the best packaging that meets conflicting demands such as straightforward assembly, effortless opening, ease of disposal and recycling, and cost performance.
Experience accumulated over more than a century gives
rise to the difference in quality
Rengo has a history of over 100 years as the leading company in corrugated packaging and other packaging, accumulating a vast amount of precious experimental data and knowledge not found elsewhere. Package testing—such as compression, vibration, and dropping—and environmental testing recreating temperature and humidity during the logistics process are also conducted under conditions as close to actual conditions as possible. In addition, we also carry out design with various ingenuities taking into consideration the psychological aspect of people handling parcels, such as using structures where the products within can be seen to encourage handling with care.

Designing numerous innovative packaging that transcend existing mindsets
From RSDP—an innovative packaging which has drawn attention for bringing together all the functions of being easy to transport, display, and sell—to the S-Lock Tray for fruit which balances significantly reducing the area of corrugated board used while improving workability in assembly and disassembly, and our rich lineup of no-staple corrugated boxes and cushioning materials. We use our strengths—such as diverse human resources with different specializations, and collaboration between the Packaging Machinery Department and design departments—to bring forth many products changing the history of packaging.
