The Zelsnap technology provides an unobtrusive, flush-fit butterfly hinge which facilitates the design of neater, more attractive dispensing closures and forms the cornerstone of the many and varied standard and custom designed dispensing closures produced at Norwich for a wide range of markets and applications for tubes and bottles.

With the significant rise in demand for closures that not only perform the basic closure function, but also provide convenient flip-top dispensing characteristics, Zeller Plastik has built a comprehensive range of dispensing closures to suit a wide variety of markets.  The addition of the ZelValve silicone valve dispensing closure system is a further development of this technology and provides consumers with a clean, non-spill dispensing system.
