I cutted this plastic wrapping with scissors, by pressing, not cutting, in one slide.
Can anyone explain me this shape?

All I see is a squiggly line in the middle..?

I tried to make a straight line, the scissor may have shaked or something, but thats wierd.

it looks pretty uniform so this isn't accidental.

these are the solutions that come to mind

1.you are bullshitting
2.you use scissors with a blade shaped like that
3.this was done at the factory so you can rip the package open without cutting it and you simply didn't notice it

did you pull it apart while you cut it?

It was on a 2l of coke, its how I was able to cut by pressing not cuting

cutting without cutting doesn't make sense.

did you stab it with the end of the scissors?

if so this is probably caused by the inward force deform the flat surface make it irregular shaped when it finally cut through.

I used to have Plastic Crayola Scissors that cut just like that

It start with a straith line then the wave begin with the non uniform part, after it look pretty symetric.
