Packaging design & various types of packaging
Tray-type corrugated packaging S-Lock Tray
This is a small tray with a crosspiece for small volume needs such as tomatoes. It holds 1 to 2 kg in weight, and significantly reduced the amount of corrugated board used. It has a locking mechanism achieved by just sliding the flap, making assembly and disassembly very simple. When used with a specialized forming machine (TTM-14S), it can also handle large demands.
Tray-type corrugated packaging L-Lock Tray
This is a medium-sized tray mainly for fruit and vegetables holding a weight of 3 to 4 kg. The amount of corrugated board used was reduced through the new structure which reinforces the four corners. The crosspiece was eliminated by using a stacking structure that does not crush easily, thereby also improving display performance. When used with a specialized forming machine (TTM-18L), it can also handle large demands.
Rengo's No-staple corrugated box
Rengo actively takes on the development of corrugated boxes that do not require sealing materials such as staples and tape. Through designs that maximize the characteristics of manufacturing facilities with almost no change to the amount of corrugated board used or cost, Rengo achieves reduced effort in sealing and unpacking as well as using fewer resources by reducing sealing materials. These boxes are widely used mainly for fruit and vegetables.
This is a no-staple lock developed for top sealing. It can lock boxes fully packed to the brim without damaging the products within.
This is a no-staple lock developed for bottom sealing. The crab-claw shaped flaps demonstrate outstanding performance in preventing the bottom from falling open. Depending on the product, it can also be used for top sealing.
Corrugated cushioning materials
From cushioning design for electric and precision products vulnerable to impact, to large assembly packaging for heavy components, Rengo responds to all of these with recyclable corrugated packaging. We developed various types of packaging in accordance with product characteristics, including the use of Rengo’s unique zigzag cut in design.
Rengo has an assortment of numerous flutes that allow the reduction of environmental impact and optimization of packaging for various types of products.
What is Delta Flute?
This is corrugated board developed by Rengo with a thickness of approximately 2 mm, between that of B-flute (approximately 3 mm) and E-flute (approximately 1.5 mm).
Compared to B-flute, the box stacking limit has been increased by approximately 30%, allowing transportation and storage space to be used effectively. It is also not bulky upon disposal.
Compared to B-flute, it is easier to assemble, can be formed better, and allows for even sharper printing.
Friendlier to the environment
Compared to B-flute, it uses approximately 8% less corrugating medium, and CO₂ emissions are reduced by approximately 3%. It has a higher number of flutes than B-flute, making it excellent for use in lightweight containerboard, and can be made even more lightweight.
Compared to E-flute, crush strength has been improved by approximately 35%. When used for inner boxes, it allows piling as it is has films for storage and transportation, allowing for the elimination of outer boxes.
