Polyethylene is a non-polar material
,
and its film has low surface tension
.
Generally
,
the surface tension of the film can be reached by corona treatment
.
Better printing results can be obtained above 38dyn/cm
.
This development is to select appropriate raw and auxiliary materials and reasonable process formulas
