“Copper Stopper™”, developed with Mitsui Chemicals proprietary technology, is a new material coated by vapor deposition nano-coating technology in the thickness of 10 to 100 nanometers. Use of alloy technology resolves the problem of corrosion to which copper is prone.

Ace Co., Ltd. collaborated with world-class designer, Oki Sato of Nendo to refurbish their key luggage brand, ProtecA, by reinforcing its high quality and high functionality with next-generation, high design. In line with their concept for ProtecA GENIO CENTURY, Mitsui Chemicals Industrial Products introduced traditional Japanese techniques used in making gold and silver threads for the copper alloy threads used in the luggage line’s innovative and next-generation interior fabric “copper jacquard”.

The Mitsui Chemicals Group will continue to pursue expansion of applications for “Copper Stopper™” to improve quality of life.

Reference 2) Superior Antibacterial Effect of copper

Copper, an essential nutrient to humans, is known to be highly effective as an antibacterial agent in inhibiting the spread of infections such as A -type influenza virus and MRSA (methicillin -resistant Staphylococcus aureus). It is also known to inhibit growth of fungi such as Trichophyton. Copper’s anti-allergen performance against cedar pollen and mite allergens has also been noted in recent years. In March 2008, the United States Environmental Protection Agency (EPA) approved registration of antimicrobial copper and copper alloys, the first and only solid materials to receive this type of EPA registration*1. As a result, antimicrobial copper alloys have received global attention and are being adopted in hospitals, health and welfare establishments, nurseries, and other facilities requiring hygienic environmental conditions*2.
