Easy to open and close
Our designs enables the user to open and close the SANZIP zippers with ease whilst maintaining a strong holding force from the inside. Our zippers undergo stringent quality inspections throughout our manufacturing process to ensure that uniform standards for easy opening are maintained. With outstanding compatibility with a wide variety of packaging machines, our zippers provide a constant opening performance for stand up, and flat bottom pouches to enable an easy filling process.
SANZIP zippers feature a strong internal holding force to prevent opening due to pressure from within the pouch. The pouch contents are protected from external pressure and a secure seal is maintained during the filling process. The zipper maintains a strong holding force even after repeated openings.
