Corona treatment pens, dyne pens, corona treatment pens, and plastic film surface tension test pens. Corona treatment pens are tools for measuring the corona density (dynes) of film surfaces and are specifically used to determine the effectiveness of corona treatment on films. Corona treatment pens are available in a variety of tensions, including 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, and more. These pens accurately determine whether the surface tension of plastic films meets the specified value. This allows users to clearly determine whether a film is suitable for printing, lamination, or vacuum aluminum plating, effectively controlling quality and reducing losses caused by substandard materials.
Corona treatment pen applications
Suitable for gravure printing, offset printing, and UV printing. Corona treatment pen specifications: 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60.
