As before, I'm going to try applying heat to a different kind of aluminum deposition material with about 500 watts in the microwave.


Compared to the packaging of the chocolate pie, the amount of heat that passed through the Ramune pouch this time was higher, perhaps because the ratio of the amount of laminated aluminum material was higher.




probably because it also contained more resinous acid, it retained more heat.

The cause of the cut line in the shape of the A is unknown, but it may be a difference in the shrinkage rate.

In other fields, cracks appear in special paints due to differences in the shrinkage rate of the ink, but what triggers these changes is a phenomenon that can be applied to other materials.
