At Zhejiang Gint, we specialize in manufacturing high-quality vacuum flask water bottles that cater to both industrial and commercial needs. Our products are designed with advanced double-wall insulation technology, which creates a vacuum between the inner and outer layers to significantly reduce heat transfer by conduction and convection.
