Haze can make transparent packaging appear cloudy or dull, affecting product visibility and perceived pack quality.
Measuring haze can support material comparison, specification and quality requirements, and investigation of changes in optical performance.
Transmission haze results from light scattering as it passes through a material. Testing can also be used to evaluate the effects of weathering, surface abrasion or other environmental exposure by comparing haze before and after exposure.
Smithers measures haze using the spectrophotometer method in accordance with ASTM D1003, Procedure B.
