Application Support

Non-porous substrates, such as polyethylene, polypropylene and foils, need to have their surface energies altered in order for the proper flexographic ink adhesion to occur.

There is no easy way to determine changes in surface energy on non-woven and woven substrates and we know of no official standards such as an ASTM method but there is a procedure.

What is the ideal distance between the treatment head and the surface to be treated? The answer depends on the surface treater you are using and your specific application. However there are some general guidelines that you should be aware of

We're often asked what dyne level do I need to print on a particular type of  film. Its a complex question that includes many variables beyond the material  type and method of printing or coating. We can however provide general  guidelines that you can use to start your own evaluations.

This method provides a fast and easy check of the treat level of a substrate using dyne test marker pens.

Precisely formulated wetting tension test solutions are available from Enercon Industries Corporation. Wetting Tension Test Solutions identify the ideal corona treat level setting for production of extruded film and for converting processes.
