Since the beginning of our firm , in 1983, we have been working to find a solution to the problem of welding or tieing the stems of balloons by hand. The way to solve it was to use a self-selling laminate valve from which existed several types, which once exami-nated they seemed to us to be not very sure and antique. Mainly what it refered to the application of these valves to the balloon.

For this reason we developed a new system which consisted of welding the valve within one of the films of the balloon, where a hole had been made previously. In this way the valve can be placed in any part of the balloon and not only in the stem. Besides it has an internal strangulation in the body of the valve characteristic of our valve, which gives a perfect self-selling.

To protect this job the following patents were realized:
