When sourcing TNT fabric, the price is primarily driven by GSM (Grams per Square Meter), which typically ranges from 10gsm to 150gsm. You must specify the raw material composition, such as 100% Virgin Polypropylene (PP) versus recycled content, as virgin material offers superior tensile strength and uniformity. Additionally, consider the web-forming method (Spunbond, Meltblown, or SMS) and functional treatments like UV resistance, anti-static, or hydrophilic properties, which will impact the final quotation.
