Wettability and contact angle
Wettability and contact angle

Wettability is the ability of a liquid to spread out completely on the flat and horizontal surface of a solid. It is measured in dyne/cm.

Corona treatment for blown film extrusion lines
Corona treatment for blown film extrusion lines The blown film extrusion is one of the most common methods for obtaining plastic films from molten plastic materials.
Corona treatment for cast extrusion
Corona treatment for cast extrusion Technology is more complex compared to blown film extrusion but offers a series of advantages such as uniformity of the film thickness, greater flexibility in selecting the type of polymers to be used, high optical features (film transparency and clarity).
Why corona treatment?
Why corona treatment? The primary effect of the corona treatment is to activate the surface of the film, that is,to increase the surface energy measured in dyne per centimetre (dyne/cm).
Plasma treatment at atmospheric pressure conditions
Plasma treatment at atmospheric pressure conditions Often, materials used in the manufacturing sector need to have particular surface characteristics. Plasma treatment cleans and activates plastics, cardboard and metals.
Destructioning the ozone produced by the corona treatment
Destructioning the ozone produced by the corona treatment The corona treatment stations produce ozone (O 3  a polluting molecule) that does not dissolve in the air, increases the levels of photochemical smog and can be detrimental to human health.
