Dispensing and Coating Services Precise Gluing · Breathable Bonding · Custom Patterns
We specialize in irregular dot dispensing, strip coating, partial area gluing, and personalized pattern coating. Unlike full roll lamination, our process retains the original softness and air permeability of your materials. Fully compliant with international environmental standards.
Difference between dispensing coating and lamination & back coating services
Precision application that preserves material integrity while ensuring superior adhesion.
Laminating
Full surface tight bonding, resulting in complete multi-layer composite coverage. High strength but zero breathability.
Back Coating
Even full gluing on a single side with a sealed lamination effect. Adds weight and stiffness to the material.
Dispensing & Coating
Discrete dot & patterned gluing, partial area bonding. Excellent air permeability and soft texture preserved.
Dispensing and Coating Services Core Competitive Advantages
Engineered for precision and versatility. Our advanced coating solutions deliver flawless integration without compromising your material's inherent qualities.
Customizable Glue Patterns
Irregular dots, regular dots, strips, grids, and logo patterns are all available, produced precisely as per your design drawings.
High Dispensing Precision
Independent nozzle control ensures accurate glue output, eliminating overflow and missing spots for flawless production.
Preserve Original Properties
No hardening after gluing. Fabric elasticity, soft touch, and air permeability remain completely intact.
Flexible Processing Range
Support small-area partial gluing, narrow strip dispensing, and complex special-shaped contour coating.
Reliable Environmental Performance
Solvent-free formula with zero harmful emissions. Fully certified by RoHS, REACH, and California Proposition 65.
