Cost-Effective: 1-ply napkins are generally less expensive than 2-ply or thicker napkins, making them a budget-friendly option for restaurants, events, or personal use where high absorbency is not a priority. Sufficient for Light Use: For meals or settings where napkins are only lightly used, such as with finger foods or less messy meals, 1-ply is often enough and minimizes waste. Bulk Convenience: Since theyre thinner, theyre easier to store in large quantities. This can be practical for businesses or events needing many napkins without occupying much space. Overall, 1-ply napkins are chosen because they're practical, economical, and often provide the necessary function without added expense or environmental impact.
