Our Polyester Sewing Thread is specifically manufactured to maximize the performance of your bag sewing equipment. Enhanced tensile strength and linear uniformity means, consistent, stronger bag closures. Plus, you get longer shelf life with our polyester thread because it's not susceptible to the effects of moisture, mildew and UV light. And, our high yield format means you get more thread per cone. The sewing thread is compatible with most brands of industrial bag sewing equipment.
