Cotton bags are environmentally friendly in terms of their raw materials. Material specifications for cotton bags are typically expressed in terms of weight (grams) and "ounce" (oz) ratings; for instance, a poly-cotton blend weighing around 300g is classified as 12 oz, while pure cotton weighing around 270g is also 12 oz. Custom production commonly utilizes 12 oz and 16 oz materials. Since the cost of cotton fabric is generally higher than that of non-woven fabric, organizations that choose cotton bags often place a greater emphasis on environmental considerations. While cotton bags are biodegradable, their actual environmental performance depends on production and usage conditions-for example, the use of non-eco-friendly dyes can affect the biodegradation process. Cotton bags are generally more durable than non-woven bags; quality standards include weave density-with a density exceeding 200 threads per square inch typically indicating high quality-which directly impacts the bag's strength and longevity. Cotton bags feature a fine texture, often yielding superior printing results compared to non-woven bags; the fabric is soft, making the bags easy to fold and carry, and they are also easier to wash than non-woven alternatives. Although frequently used as shopping bags, their widespread adoption is limited by higher costs and more complex manufacturing processes.
