Current work and context

I currently work on product development for DIAMIRON™, a co-extruded multilayer film. By simultaneously extruding and forming multiple resin layers, we create a single film with various functionalities. For example, we can tailor it to specific applications by imbuing it with essential qualities like gas barrier properties that make it difficult for oxygen or water vapor to pass through (thus keeping food fresh), or heat resistance.

This film is used in a wide variety of fields, from food packaging for items such as ham or sausage found in convenience stores and supermarkets, to packaging for medical devices.

Tackling the issue of waste reduction through food packaging

Addressing resource and waste issues has become a major challenge. To tackle this issue, we are working on developing thinner films that maintain performance, as well as utilizing biomass materials. We also aim to reduce food loss and waste by enhancing the gas barrier properties of our films.

At the same time, recycling remains a difficult area. In Japan, recycling systems are not yet fully established through the market. Furthermore, the multi-layer structure of films, which combine multiple materials, makes them inherently difficult to recycle.

Toward easily recyclable materials without compromising on functionality

DIAMIRON™ previously was comprised of multiple layers of materials with differing properties, such as polypropylene and nylon. Therefore separation was difficult, making the product unsuitable for recycling. To address this, we are now exploring ways to improve recyclability by converting it into a mono-material (single material structure) using only polyolefin-based resins such as polyethylene or polypropylene. As demand from society and our customers is growing every day, the hurdles for development have reached unprecedented levels. While the path forward is not always smooth, we remain committed to seeing things through and never giving up. By meticulously analyzing challenges and approaching them from every angle, we strive for breakthroughs.

Creating a future that balances waste reduction and consumer convenience

I believe that the development of products such as resealable films, which can be closed again even after opening and that reduce plastic usage while improving convenience for consumers, is an important theme that will lead to the creation of great value. While food in conventional packaging can dry out after opening, resealable films allow users to take out only what they need and repeatedly open and close the package, eliminating the need to rewrap leftovers with plastic wrap. We seek to keep developing new films with such advanced features that add value and grow our business into one that enriches people's lives while reducing waste.

What KAITEKI means to me

For me, KAITEKI is hope. It means leveraging the knowledge I　have cultivated as an engineer to bring to life new solutions through DIAMIRON™ that are both resource-conscious and conveniently useful. I believe that each step we take will lead to a sustainable future brimming with hope.
