Do you ever wonder how the basic material outside of a high-quality heat patch is made? Follow me, let’s see this video, which is Hanyao’s non-woven workshop and raw material warehouse.
We control the quality from the very beginning, that is we can produce non-woven fabric and composite film by ourselves. This part is very important for quality control, including the stable temperature and duration. Because the breathability of fabric will affect the oxygen-in and heating-release.
Partner with a manufacturer that controls the source. If you want to learn more about our factory, here is our official website: www.jshanyao.com
