What SEALON does

SEALON Co., Ltd. (주식회사 실론) is a South Korean specialty manufacturer founded in 2002 that produces seam sealing tapes, adhesive films, decorative (deco) films, and specialty tapes for the global apparel industry. Its core technology addresses waterproofing at stitch points in 2-layer through 3.5-layer garments, enables seamless construction via double-sided adhesive films, and supports design customization through deco films available in 300+ colors and variants including reflective, silicone, texture, and specialty films. The portfolio has progressively expanded into recycled (EF series, EF3060), recyclable (RS301, RCA 5376), and bio-based (BBA 3030W) variants, with a July 2024 patent for ECOFIX pressure-sensitive adhesive (PSA) deco film that eliminates the pre-pressing process.

The company operates a B2B direct sales model serving global apparel brands across four vertical segments: outdoor and sports apparel (primary), workwear and safety, functional/activewear, and down/insulated apparel. SEALON monetizes through hardware sales of manufactured tape and film products at non-publicly-disclosed prices set via direct inquiry, with customers including a Technical Studio testing service and direct field engagement. Distribution is executed through eight regional offices in South Korea (Seoul Guro-gu HQ, manufacturing in Yangju, Gyeonggi Province), Hong Kong, Hanoi, Ho Chi Minh City, Shanghai, Taipei, Jakarta, and Madrid, supplemented by participation in 50+ global trade shows including ISPO Munich, Techtextil, Functional Fabric Fair, DTG Bangladesh, and FTS Shanghai.
