How to distinguish PET twist film and cellophane?
When we knead PET twist film, it sounds more sonorously and clearly. And we knead cellophane, it sounds more steadily.
The direct method is lit, lit with a lighter. PET films will shrink as the look of the plastic frit, but cellophane will turns to ash
like the paper.
