Every day, we casually pick up products without a
second thought. The packaging of these products is, in fact,
custom-made and represents the culmination of
the knowledge and technology of many people, along with
the thoughts and aspirations of our customers.
As a general packaging manufacturer,
Rengo takes a holistic approach to everything from
planning and manufacturing to transportation,
in-store appearance, ease of use, and
environmental consideration,
creating packaging that helps solve social issues.

Basic Functions of Packaging

Protection of Contents

Packaging protects contents from damage and quality deterioration caused by various hazards and risks that occur during transportation, storage, and handling from producers to end consumers.

Therefore:

  1. Prevents contamination and allows hygienic transportation
  2. Absorbs impact and enables damage-free transportation
  3. Maintains taste, nutritional value, and safety

Handling Convenience

Packaging makes handling more convenient throughout production, cargo handling, transportation, storage, sales, and consumption.

Therefore:

  1. Allows many items to be transported at once, including shapeless items such as liquids and gases
  2. Enables efficient operations during transportation, storage, and in-store display
  3. Ensures safe handling and easy storage
  4. Allows designs that make opening, resealing, and recycling easier

Providing Information

Packaging provides consumers with various types of information about producers and contents through text, illustrations, labeling, and color design.

Therefore:

  1. Communicates product names, ingredients, usage instructions, and precautions
  2. Highlights product appeal through visual and structural design
  3. Differentiates products from competitors and reinforces brand image

Creating Packaging

Design and Engineering

The Customer's Product Is the Starting Point

Packaging is developed on a custom-made basis to suit each product. Based on customer requirements such as product characteristics and transportation and storage conditions, packaging is designed with the final product in mind. Packaging and environmental tests are carried out simulating the actual logistics conditions. Designs that communicate product appeal are then created and refined through repeated discussions with the customer.

  • Packaging design
    tailored to each product
  • Design creation that conveys product appeal

Development

Balancing Functionality and Design

Depending on the intended use of the packaging, various functional features are incorporated, including LossLess and RECYCOOL. Although it is not obvious just by looking, these features help maintain the freshness and taste of vegetables and other produce over extended periods and contribute to reducing food loss. In addition, easy-to-open and visually clear designs are actively incorporated, with consideration for universal design.

  • RECYCOOL, which delivers high performance
    in freshness preservation
  • LossLess bags and films with
    freshness preservation
    functions for fresh produce

Manufacturing and Quality Control

Predicting Paper Strength Through Digital Technology

By actively introducing DX, Rengo has established a quality control system that does not rely on experience or intuition. For example, in containerboard production at paper mills, a system capable of predicting paper strength in real time has been developed and implemented. Based on these predictions, prompt countermeasures can be taken on site, reducing defective products and enabling efficient, safe, and high-quality manufacturing.

  • Digital control of the corrugating
    medium manufacturing process
  • Achieving high-quality manufacturing

Packaging Machinery and Packaging System

Efficient and waste-free packaging systems

Rengo has extensive experience in developing automated packaging systems for e-commerce. These systems automate the entire process from forming boxes sized to each product, to packaging and palletizing. By minimizing wasted space and significantly improving packaging efficiency, they contribute to reducing CO2 emissions during transportation. A key strength is the collaboration between corrugated box design teams and machinery design teams, enabling the creation of optimal packaging formats and automated equipment.

  • Development of packaging systems
    capable of forming perfectly sized boxes
  • Significant improvement in
    operational efficiency through
    automated e-commerce packaging
    systems

Resource Circulation

Recovered Paper Usage Rate of 98% or Higher

Rengo is advancing efforts to increase the recovered paper usage rate for corrugated packaging and to utilize unused recovered paper. Also, plastic packaging is developed with environmental consideration in mind, from the perspective of 2R ＋ R (Reduce, Recycle, and Renewable). Through the entire life cycle from production to end of use, Rengo is committed to providing sustainable packaging solutions.

  • Used corrugated boxes are reborn as
    corrugated boxes

Rengo not only maintains manufacturing sites nationwide, but also ensures close collaboration among sales, manufacturing, and packaging development departments. Through this integrated approach, Rengo delivers comprehensive solutions to meet diverse packaging needs across all industries.
