How to distinguish PET twist film and cellophane?
Reply:
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 twist wrap films will shrink as the look of the plastic frit, but cellophane will turns to ash like the paper.
