These defects directly resulted in product quality issues and customer complaints.<\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">The impact extended beyond product quality: responding to complaints consumed valuable time and placed a heavy burden on operators. As a result, improving the low-humidity environment became an urgent priority.<\/p>\n<div style=\"text-align: center;margin-top:2rem;margin-bottom: 10px\">\n            <img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/09\/hum-paper-003-002.webp\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><figcaption style=\"margin: 1rem auto 3rem;text-align: center;font-size: 0.85rem;color: #666\">Preventing paper warping and cracking had become an urgent priority<\/figcaption><\/div>\n<\/section>\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<section>\n<h3 style=\"font-size: clamp(20px, 2vw, 30px);padding-left: 14px;margin: 0 auto 2rem;border-left: 5px solid #0c9b6f\">Solutions Proposed by IKEUCHI<\/h3>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">The proposed solution was <a href=\"https:\/\/www.dry-fog.com\/en\/products\/sol-hum-airaki\/\" style=\"color: #00a273\" target=\"_blank\" rel=\"noopener\">AirAKI, IKEUCHI\u2019s industrial humidification system<\/a> designed to prevent production problems caused by low humidity and static electricity.

Humidifying the entire space would have required a large number of humidifiers, resulting in higher initial and operating costs.<br \/>\nInstead, IKEUCHI proposed <span style=\"font-weight:bold\">humidifying the packaging paper stock storage area<\/span> before processing, allowing the material to retain sufficient moisture before entering the production line.<\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">By increasing the moisture content of the packaging paper stock before processing, the material remained flexible even after being transferred to the production area, reducing the risk of cracking and warping.<\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">Because outdoor air could easily enter the area, IKEUCHI proposed installing vinyl curtains at the entrances to reduce air exchange. This allowed the system to be designed with the optimal number and placement of humidifiers for stable and efficient humidity control.<\/p>\n<div style=\"text-align: center;margin-top:2rem;margin-bottom: 10px\">\n            <img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/09\/hum-paper-003-003.webp\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/>\n        <\/div>\n<\/section>\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<section>\n<h3 style=\"font-size: clamp(20px, 2vw, 30px);padding-left: 14px;margin: 0 auto 2rem;border-left: 5px solid #0c9b6f\">Benefits Achieved<\/h3>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">Before AirAKI was installed, humidity in the target area had remained around 10%. After installation, <span style=\"font-weight:bold\">humidity stabilized at approximately 50% RH<\/span>, eliminating unnecessary work and reducing the burden on operators.<\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">With the packaging paper stock maintained at the proper moisture content, <span style=\"font-weight:bold\">warping and cracking during processing dropped sharply<\/span>. Complaints tied to defective products, once a persistent issue, fell to nearly zero.<\/p>\n<p style=\"margin: 2rem auto 1.5rem;font-size: 1.125rem;line-height:1.6\">Humidity control in the company\u2019s own warehouse now gives the customer greater flexibility in inventory management. The operation is less labor-intensive, and workflow efficiency has improved significantly.<\/p>\n<div style=\"text-align: center;margin: 50px 0\">\n            <a href=\"https:\/\/www.dry-fog.com\/en\/contact\/\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"background-color: #e67f00;color: #ffffff;font-size: 15px;font-weight: bold;text-decoration: none;padding: 15px 30px;border-radius: 5px\">Contact Us<\/a>\n        <\/div>\n<\/section>\n<\/section>\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<section>\n<h3 style=\"font-size: clamp(20px, 2vw, 30px);padding-left: 14px;margin-top: 0;margin-bottom: 0.8rem;border-left: 5px solid #0c9b6f;line-height: 1.4\">SDG Contributions<\/h3>\n<p style=\"margin: 0 auto;padding: 0 10px 20px 10px;text-align: left;max-width: 100%;font-size: 1.125rem;line-height: 2.1rem\">Relevant SDG goals for this case.<\/p>\n<div style=\"--col:4;width:100%;max-width:800px;margin:20px auto;overflow:hidden\">\n<div style=\"float:left;width:calc(100% \/ var(--col) - 2%);margin:1%;height:55px;min-width:100px;background-color:#4C9F38;color:#fff;text-align:center;font-size:13px;line-height:1.3;padding-top:12px\">3.
