In order to investigate the effects of different materials, structures and sizes of paper packaging zippers on the maximum tearing force (Fmax) and the consumers’comfort level in opening process, the angular paper packaging zipper，the arc shaped paper packaging zipper and the sloping paper packaging zipper with white cardboard and gray cardboard as the wrapping materials were prepared by the flatbed cutting machine. The Fmax were tested by changing the size of horizontal projection (a), vertical projection (b) of the front tilt part of the zipper monomer and the circular arc radius (R). The consumers’comfort level in opening process was measured by changing the zipper width of paper packaging fixed other variables. The results showed that the Fmax required for white cardboard samples was larger than that of gray cardboard samples. The Fmax of the sloping paper packaging zipper was the largest and had poor opening effectiveness. The Fmax of the paper package zipper increased with the increase in the size of structure variable a, b, R. If the size of a, b, R was too small, the paper packaging zipper would break down, while the size exceeded a certain value, it would not open smoothly. In the ergonomic test, the width of 17 mm indicated the highest satisfaction value for people.
