Inventor

Thomas Sutrina

The list of patents below shows the range of inventions that I have been involved in. The Zip loc patents were done under significant stress. If you choose to check you will find Dow Chemical Started building the sandwich bag plant and order equipment prior to my acceptance of the assignment to the group. I had 9 months to define a robust zipper and film extrusion process to go in the plant.
This case stands out, but it is not unusual.
