Individual Blue Pen


SKU: 17-05xx Category:


To make possible the printing and adherence of polymer plastics it is inherent that the surface be treated, so that the surface tension rises to a defined point.

Untreated PE and PP have a surface tension of about 30 dynes/cm. Well treated PE and PP should have a value of about 38 to 41 dynes/cm for printing.

Polymer plastics with a surface tension of less than 37 dynes/cm have binding difficulties. This is recognized in that the tape pull-off test has a negative result.

The value of treatment is tested by simply brushing the testing inks/pens onto the surface.
