T-rip / cookie bag

Sometimes it is difficult to open the cookie packages. Some packages with zigzag edge is easier to tear but the edge would not be the top and easy to spill cookies on the ground. If we want a nice and easy-made edge, is can only be cut with scissors.
So we tried to figure out an easy way to make a nice edge without tools. We make a cornor instill of a straigh line when it is sealing. T-Rip support an anlge when we rip the package and make it more easier to open and enjoy the snacks.
