How to detect the surface tension of plastic film?

Answer:

Use a pen and a ballpoint pen to draw lines or write on the surface of the film, and judge whether the lines drawn by ink or ballpoint pens are continuous. Lines can be printed continuously, otherwise they are not processed enough.
To judge the smoothness of the surface of the plastic film by hand, the more smooth the surface of the film is, the better the surface treatment of the film is.
A layer of ink used to bind a printed film with paper tape. The less the ink is stuck, the better it is treated. To peel off the bonded composite film, the greater the peel strength, the better the treatment effect.
