The team started to focus on research and development of airtight zippers, watertight zippers, nylon interlocking zippers, smiley zippers (curved zippers) and other special zippers in 2013. Over the years, we have independently developed relevant production equipment, technology, and material formulas, obtaining a number of patent certificates in the field.
