The product information for reinforced cardboard "Naviace" and reinforced cardboard pallet "Navipallet" has been updated.

Reducing environmental impact, achieving SDGs goals! Completely in-house production, domestic production, and mechanization ensure reliable quality! (For export and one-way disposable use)

【Specific Details】 - Significant reduction in carbon dioxide (CO2) emissions is possible. - Costs are reasonable compared to export wooden fumigation pallets and plywood pallets. - Fully produced in-house, with a mechanized production line ensuring reliable quality. - Less susceptible to price and delivery time fluctuations due to international circumstances, as it is completely domestically produced. - Made of cardboard, so quality is more stable than wood. Many people are concerned about quality, but our cardboard pallets: - Are designed according to the strength requirements of the specific products (completely custom-made). - Ensure stable quality through mechanization of the production line (and pricing as well). - Have a proven track record of numerous deliveries to major companies. We hope this provides you with peace of mind. 【Disadvantages】 - Designing for your peace of mind takes time. - Not very suitable for repeated use (generally one-way, disposable). - Weak against water (if it weren't, it wouldn't decompose naturally). ↓ For more detailed information, please download and review the materials below ↓ *Since it is completely custom-made, we will assess whether "cardboard conversion" is feasible. We would appreciate the opportunity to hear about your situation first.

★We are minimizing the necessary materials as much as possible★ Achieved 1-ton suspended packaging with cardboard!!

[Development Background] Special films and metal foils (such as copper and aluminum foils) are generally not allowed to be bottomed out in order to protect the contents, and are packaged and transported in a suspended state with the axis held by supports on both sides. Therefore, they are often packaged in sturdy wooden boxes, steel cases, or boxes made from a combination of different materials. Using reinforced cardboard "Naviace" and reinforced cardboard pallets "Navipallet," we aimed to achieve an all-cardboard packaging solution that was previously thought impossible by leveraging our design capabilities. The development period was three years. After repeated trials and errors, we finally succeeded. ★ We spare no effort in solving social issues and our customers' challenges ★ At our company, which has this corporate culture, would you like to work together to solve your challenges? ↓ For more details, please contact us or download the catalog ↓

Proposal for increased productivity alongside CO2 reduction through all cardboard packaging! Do you think that SDGs and costs are in conflict with each other?

Many people think that "eco-friendly products are expensive." In reality, there is such a tendency. Therefore, even if you try to engage in SDGs aimed at reducing environmental impact, it often doesn't go as planned, and you may find yourself unsure of what to do. With our all-cardboard packaging (cardboard pallets, heavy goods packaging, collective packaging, functional packaging), we can provide benefits that are not only related to the environment, such as: - "Reduction of environmental impact CO2 emissions (achieving SDGs goals)" - "Improvement in productivity" - "Increased logistics efficiency" 【Examples】 - 90% reduction in CO2 emissions - 30% reduction in logistics costs due to improved transportation efficiency - 30% reduction in packaging time due to improved work efficiency - 30% reduction in labor costs due to improved production efficiency *It cannot be generalized as the packaging materials currently used vary by customer. 【Other Benefits】 - Packaging can be done by anyone (even women and the elderly) - Unpacking during recalls or re-inspections has become easier - Company logos and other designs can be printed, enhancing company promotion and image - If labels are printed, there is no need to stick them on separately Since it is completely custom-made, we will design it according to the customer's usage situation and requirements.

I summarized the features of the reinforced cardboard "Naviace" (its differences from other cardboard) using a positioning map, aiming to make it as "easy to understand" as possible.

What is the reinforced cardboard "Naviace"? In discussions with customers, we received feedback such as, "If I had known, I would have understood its advantages, but at first, I couldn't tell what was different from other cardboard." Indeed, the appearance of Naviace is the same as other cardboard, making it difficult to understand (and convey) what is good about it and what benefits it offers. Therefore, we created materials using analytical methods like positioning maps to communicate in a way that is "as easy to understand as possible." Specifically, we focused on: - Heavy - Complex - Seeking quality and aesthetic appeal, among others ★★ For more details, please download the materials below ★★ [Main Improvement Proposals for Reinforced Cardboard "Naviace"] ■ Environmental issue improvements (SDGs, carbon neutrality, Scope 3, decarbonization CO2 reduction, resolution of wood shock, etc.) ■ Reduction of cubic meters (improvements in logistics transportation, storage efficiency, resolution of export container shortages) ■ Anyone can pack and unpack (improvements in work efficiency, productivity, waste reduction, etc.) ■ Enhancement of corporate image (ESG investment measures, CSR measures, response to Scope 3)

The increase in costs is a hurdle for carbon neutrality. Achieve both carbon neutrality and a reduction in total logistics costs with reinforced cardboard "Naviace"!

"When addressing environmental issues and the SDGs, it often results in increased costs." By using reinforced cardboard "Naviace," it is possible to achieve both decarbonization and cost reduction. 【Environmental characteristics of Naviace and the concept of cost reduction】 ◆ Compared to wood, plastic, and metal, it emits less CO2 from production to disposal (recycling). ◆ The material is lightweight, which reduces CO2 emissions during transportation. ◆ Its easy design and processing allow for improved logistics efficiency through volume reduction, leading to a decrease in CO2 emissions. → Thus, it is an environmentally friendly material due to its material characteristics. In other words... ★ The lightweight nature of the material directly leads to cost reduction as a material. ★ The ability to improve logistics efficiency results in reduced shipping costs and packaging labor costs. For these reasons, "carbon neutrality and total logistics cost reduction can be achieved." ↓ If you would like to know more details, please download the materials below ↓
