Seamless Underwear
Invisible Comfort, Effortless Freedom

In intimate apparel manufacturing, fabric lamination must withstand daily challenges including high-frequency stretching, machine washing friction, sweat exposure, and body temperature fluctuations. Traditional adhesives often lead to issues such as hardening, adhesive failure, and visible glue marks. SINOHESIVE specializes in PUR (Polyurethane Reactive) bonding technology, delivering invisible yet robust lamination for ultra-thin fabrics like lace, modal, and spandex—enabling a truly seamless, zero-sensation wearing experience.

Core Advantages
Ultra-Thin yet Strong Bonding

A 0.01-mm-thick adhesive layer achieves molecular-level penetration, with peel strength >5.2 N/cm (ASTM D903). Resists over 10,000 tensile deformations without edge lifting or delamination.


Genuine Invisible Seamlessness

Precise rheological control eliminates glue marks, color bleeding, and grittiness. Passes light transmission tests for 20D ultra-thin fabrics (ISO 105-B02), preserving the fabric’s innate breathability and skin-friendly feel.


Safety and Skin-Friendly Certification

Biocompatible formulation certified by OEKO-TEX® STANDARD 100 Class I for infants. Complies with GB 18401 National General Safety Technical Code for Textile Products. Zero allergens added.
