Haze/transparency
Method for quantification of the optical properties of transparent or translucent materials (not coulored opaque or metallized). The test method describes the hazing of a film caused by light scattering. A low haze value characterizes a low turbidity equivalent to a good visibility of details of filling goods or labels lying behind or under the film. By increasing the haze value, the "frosted glass effect" increases, i.e. details such as labels are ultimately only recognisable when in direct contact with the film surface.
ASTM D 1003 = calibration without compensation port, DIN ISO 13468 = calibration with compensation port.
The measured values differ slightly, but the measurements are basically carried out according to the same principle.

This test measures the optical clarity of transparent or translucent films by quantifying light scattering. The film sample is placed in a haze meter to determine how much light deviates from the incident beam, with measurements following either the ASTM D 1003 or DIN ISO 13468 standards.
The resulting haze value indicates the level of turbidity, where a low value represents high clarity and a high value creates a frosted glass effect. This data is used to ensure that consumers can clearly see the product or labels through the packaging material.
