Why Does PE Material Printing Fall Off?

Nov 06, 2019

If the bottle of PE material is printed directly, it has no fastness and will fall off quickly. Because the PE material is oily, the screen printing ink is difficult to adhere to.

 

       The general solution is to melt the oil film on the surface of the bottle by heating at a high temperature. Printing must be completed within 48 hours after heating, and if it is exceeded, the surface of the bottle will re-form the oil film.
