The choice of material determines durability and cost-efficiency. For heavy-duty industrial use, prioritize high-denier polyester (600D or above) or nylon for superior tear resistance. For eco-friendly retail packaging, look for GOTS-certified organic cotton, recycled PET (rPET), or jute. Ensure the fabric weight (GSM) aligns with your load-bearing requirements; for example, a standard promotional tote should be at least 140-180 GSM to ensure it is not translucent and maintains structural integrity.
