In recent years, the electronic components industry has been accelerating supply chain-wide efforts to reduce environmental impact, driven by tightening environmental regulations and growing interest in ESG investment. At manufacturing sites for factory automation (FA) and consumer equipment, demand for environmentally conscious component supply is increasing, and the transition from plastic to paper-based packaging materials is advancing. This switch to paper reels is a response to these societal demands.
Regarding the company's paper reel rollout for its photocoupler lineup, the <PC817X series> and <PC357N series> have already entered mass production and shipment, while the <PC123X series> is scheduled to begin mass production in October. This transition to paper reels maintains quality and cost equivalent to plastic reels while reducing CO2 emissions by approximately 35% across the full lifecycle of the packaging material—from raw material procurement through to disposal.
SSIC will continue to expand its paper reel packaging lineup to support ESG compliance and green procurement for customers in the FA equipment and consumer equipment markets, while contributing to the realization of a sustainable society.

*1 For the CFP (Carbon Footprint of Products) calculation, CO2 emissions from paper reels and plastic reels were compared over the full lifecycle of the packaging material from raw material procurement to disposal. The usage process varies by customer and is not included in this calculation (as of September 25, 2026). Based on Sharp research.
*2 A device used primarily to provide electrical isolation between circuits, serving roles such as separating the high-voltage and low-voltage sides of a power supply unit and transmitting signals between telephone lines and telephone equipment.
