Seeking Co-Creation Partners
Partners We Are Seeking
We are seeking companies that have product technologies such as the following and are interested in developing environmentally friendly products:
- RFID tags, labels, and inlays
- Sheet heaters and film heaters
- Other products, including simple signal lines and simple antennas
What We Can Offer
We can provide the following technologies:
- Copper foil for hot stamping
- Research and development of copper foil tailored to the applications required by our partners
Market Challenges We Are Addressing
Metal patterns made from copper, aluminum, and other metals are used in RFID tags, film heaters, antennas, and other devices. Many metal patterning processes use photolithography, a technology based on photographic development, and require multiple chemical solutions.
Our Proposed Solution
We propose a metal patterning process that does not discharge waste liquid by combining our peelable copper foil technology with a process known as hot stamping.
What Is Hot Stamping?
Hot stamping, also known as foil stamping, is a technology that transfers a desired design by applying heat and pressure to a special foil film using a raised die. It has long been widely used in Japan and overseas as a decorative technique for book covers, posters, product labels, and other items. Over time, its application areas have expanded, and it is now also used for decorating automotive interiors and exteriors, home appliances, and electronic devices. The special foil film consists of multiple layers. It is designed so that, when heat and pressure are applied by the raised die, the foil adheres to the target substrate and can be released from the carrier.
Advantages of Hot Stamping
Process Simplification
No pre- or post-processing steps such as masking or drying are required.
Compact Equipment
Depending on the equipment, desktop models are also available.
Low Environmental Impact
No chemicals, solvents, or liquid solutions are required.
Our Proposed Copper Foil Hot Stamping Process
Based on our peelable copper foil technology, we produced a prototype copper foil for hot stamping and transferred it onto a PET substrate using a hand-press-type hot stamping machine.
This process is expected to enable copper patterning without the use of any chemical solutions.
Because this dry process can also be used for patterning on paper substrates, it is also expected to contribute to reducing plastic usage.
Principle of Copper Foil Hot Stamping
Copper foil and the substrate are pressed together using a heated raised die.
As the adhesive layer on the substrate melts and cures, the copper foil is transferred onto the substrate, enabling pattern formation
