[Japan Paper Corporation Collaboration] High-performance paper cushioning sheet 'Cu-TOP Wadding Paper' that reduces corrosive gases - Reducing the risk of metal discoloration and rust.

Are you troubled by issues during transportation and storage, such as discoloration and darkening of metal parts like copper and silver... or corrosion of circuit boards...? This product is a high-performance paper cushioning material that combines the copper ion-carrying cellulose material "Cu-TOP," developed by Nippon Paper Industries, with our unique wadding (multi-layer lamination) processing technology. In addition to cushioning and breathability, it also adds a function to adsorb corrosive gases. Thanks to the function of the copper ions contained in Cu-TOP, it contributes to the reduction of corrosive gases. Tests conducted by external testing organizations have confirmed a reduction of over 99% in hydrogen sulfide, helping to reduce the risk of discoloration and corrosion of metal products during transportation and storage. Furthermore, by laminating multiple layers of paper, it can be used as cushioning material that protects products from impact, vibration, and abrasion while utilizing the breathability unique to paper materials. It can also be customized in processing and shape to suit various applications, such as size cutting and roll winding. 【Features】 ■ Reduces hydrogen sulfide by over 99% with the power of copper ions ■ Reduces hydrogen sulfide from 4 ppm to less than 0.01 ppm in 2 hours in a test container ■ Adjustable thickness of the tissue layer for cushioning *For more details, please download the materials or feel free to contact us.

basic information

【Three Features】 (1) Over 99% reduction in hydrogen sulfide! Reduces the risk of discoloration and corrosion of substrates and metal parts. Tests conducted by external testing organizations have confirmed a reduction of over 99% in hydrogen sulfide. This next-generation cushioning material features an adsorption function that protects delicate electronic components from corrosive gases. (2) Excellent cushioning and breathability combined. Our unique wadding processing protects valuable products from shock, vibration, and abrasion. Unlike plastic cushioning materials, it offers excellent breathability and flexible processability unique to paper materials. (3) Contributes to plastic reduction and green procurement with paper cushioning material. This environmentally friendly paper cushioning material is based on cellulose. It can also be suggested as a switch from traditional plastic cushioning materials.
