When B2B buyers search for garment bags with polished finish or glossy surface treatment, they're typically referring to bags with smooth, reflective exterior surfaces achieved through specific coating processes. However, the term "polished" in the context of fabric-based garment bags differs significantly from hard-shell luggage terminology.
Surface treatment for garment bags encompasses several distinct technologies:
Surface Treatment Types for Garment Bags: Technical Comparison
| Treatment Type | Visual Appearance | Water Resistance | Breathability | Durability | Cost Index |
|---|---|---|---|---|---|
| PU Coating | Smooth, slight sheen to glossy | 1500-10000mm HH | Good (500-10000 g/m²/24h) | Excellent | 1.5-2.5 |
| PVC Coating | High-gloss polished look |
| Non-breathable | Very High | 1.0 |
| DWR Treatment | Minimal visual change, matte | Water-repellent only | Maintains breathability | Wears off over time | 0.1-0.2 |
| TPU Lamination | Premium smooth finish | Excellent waterproof | Moderate breathability | Superior | 2.0-3.0 |
| Waxed Canvas | Rich patina, semi-gloss | Good water resistance | Breathable | Requires maintenance | 1.8-2.2 |
For garment bags specifically, polished finish typically means either PU coating with higher gloss level or PVC coating. The choice affects not only aesthetics but also functional performance including water resistance, cleanability, and long-term durability. Industry data shows polyester accounts for approximately 70% of travel bag materials, with nylon commanding a 20-40% price premium depending on denier and coating specifications [2].
