Eco-friendly product development

Demand for environmentally-friendly packaging is growing as we strive to achieve a sustainable society. We conduct research and development of environmentally-friendly products from the perspectives of materials, design, and technology. Core product development is handled by the Packaging Laboratory and by the Materials Development Section. Packaging Laboratory is engaged in development, mainly in structural design of folding paper cartons and corrugated boxes, in cooperation with the company’s own plants, etc. The Material Development Section conducts research and development mainly in the field of materials and technology in cooperation with other companies.

We’ve developed paper trays to replace the molded plastic trays used to retain product shapes and prevent crushing. Their special design retains the tray shape by folding along the lines to hold the sides in position. These products have been developed for markets for snacks and other food products as trays for use with individually wrapped products.

Product features

• Paper trays can help reduce plastic use
• PSpecial design holds tray shape
• Highly cost-effective on initial costs

As part of the Craft series of paper-based film packaging seeking to reduce plastic use in film packaging, we’ve developed the fully film-free Craft Barrier^® HEAT SEAL GRADE, which has barrier properties and is recyclable.

Product features

• Fully film-free
• Oil repellent with oxygen and vapor barrier properties
• Recyclable when clean

We’ve developed paper food containers with fog-resistant windows to help reduce plastic use. The film window on the upper face of the container top features a proprietary antifogging treatment to prevent fogging due to temperature difference when a warm food product is placed in the container. As an alternative to plastic containers, paper food containers that make the contents visible will help promote switching to paper packages in the growing home meal replacement and takeout food markets.

Product features

• Paper food containers that make the contents visible
• Window prevents fogging when a warm food product is placed in the container
• Eco-friendly product with low plastic content
