The word "indentation" is generally used to decribe dents in hard surfaces. It is something you feel more than you see. Serration is a better word in this case because it decribes the wave shape cut edges.Source(s): jim

鋸齒狀（波浪狀）的邊 -- serrated edge (as master jim said)
缺口 -- notch

Can you find any indentation sided the package ? Just tear it, then it can be opened.

If you don't mind may I ask why the word of "identification" can not be used here as "serrated " ?
