Before
Image captured by a normal optical system.
Due to the high reflectance of the film, it looks white overall, making it difficult to distinguish between the welded part of the film and the bottle.

After
Image captured by a special optical system.
Since only the flat part of the film is whitened, it is possible to distinguish the welded part from the bottle.
If there is a welding defect, it will not turn white, so it will be possible to detect the defect.

[Main characteristics]
A special optical system is used to inspect the film welding condition of the cream container.
When this optical system is used, the welded part looks bright,
so it is easy to tell whether the welded part is normal or there is a poorly welded part.
