The surface of films used in food packaging, industrial materials, and medical applications feature various properties, such as transparency, gloss, waterproofness, antifouling, and non-adhesiveness. Surface treatment and processing are applied to add various surface functions.
To evaluate the quality of the surface treatment and processing on film, it is important to measure surface roughness. This inspection measures the roughness of fine irregularities on the film surface and quantifies it numerica
