What should I do if the blister box is welded and the edge can't be torn open?

1, first of all, the blister box is welded and the edge can't be torn open. It is opened with a blade and requires highly skilled technicians to operate it.

2. Find something that conducts heat, heat the screw with an iron, and when it cools down, you can unscrew it.

3. Finally, dip a little 502 glue in the top of the small screwdriver, stick the small screwdriver and the screw together and unscrew it.
