Gloss measurement
Reflectometer measurement to determine the degree of gloss. The measuring angle depends on the surface of the sample (measuring angle: high glossy: 20°, medium glossy: 60°, matt glossy: 85°).

The gloss measurement determines the surface reflectivity of flexible packaging materials using a reflectometer. A light beam is directed at the sample at a specific angle—20°, 60°, or 85°—depending on the expected gloss level, and the intensity of the reflected light is measured.
The resulting value indicates the visual glossiness of the material, ranging from matt to high-gloss. This measurement is used in practice to ensure consistent surface quality, verify the effectiveness of coatings, or maintain brand-specific aesthetic requirements for packaging.
