Suitcases and travel bags are mainly constructed of thick and hard-wearing fabrics. Therefore the threads incorporated into them must hold up to physical demands of constant packing, loading, and shuffling from place to place. It’s also important to consider UV and water resistance properties while choosing heavy duty sewing thread to make suitcases and travel bags that always exposed to UV and may encounter humid weather or even rains. Rongdu offers high quality filament thread for sewing that can withstand the friction, forces and even challenging weather conditions.

Rongdu bag stitching thread – specially designed for tough, heavy fabrics such as canvas, oxford fabric, PU, PVC, and more.
Heavy duty polyester thread like the tex 90 bonded polyester thread is recommended for suitcases and travel bags.
Polyester thread is hardly pilled, which means under no circumstance the thread frays at its edges and reduces the strength of the seams where the fabric is joined together. This is important because, in most bags, a seam will rip before the fabric does.
Bonded polyester thread is often used for superior brands since it has higher strength, produces firmer stitch and endures more challenging environment.
