Why Fabric Weight (GSM/Ounces) Matters
Fabric weight, measured in Grams per Square Meter (GSM) or Ounces per Square Yard (oz), is the single most important indicator of a cotton bag's durability and quality.
- 4-6 oz (approx. 110-170 GSM): Very lightweight. Best for simple promotional bags like calico or small pouches.
- 8-10 oz (approx. 220-280 GSM): Medium weight. A good balance of durability and cost for standard totes and drawstring bags.
- 12 oz and above (approx. 340+ GSM): Heavy-duty. This is true, robust canvas, ideal for premium retail products that need to carry significant weight.
Beyond the Buzzword: Verifying Sustainability
Any supplier can claim their products are "eco-friendly." A true partner provides proof. When sourcing organic or recycled cotton, asking for third-party certification is non-negotiable to protect your brand from "greenwashing."
At Ruixing, we believe in full transparency. We can provide all necessary certification upon request to ensure you are sourcing with confidence. Learn more in our guide to eco-certifications.
