Identifying Defects in Film

Bright, high-definition imaging

Polypropylene (PP) films are produced by applying heat to plastic to melt and extend it.
Sometimes, foreign particles mixed in raw materials and non-fused matter cause defects called “fish eyes.”
In many cases, however, these defects are difficult to see clearly due to their poor contrast.
